AutoMazar grown under Super Helios 6 led grow lights from ledhydroponics

AutoMazar grown under Super Helios 6 led grow lights from ledhydroponics

This weeks blog is an incredible Dutch Passion AutoMazar grow. Two AutoMazar’s were planted by ‘LEDbud’ with LED grow lights, who is a Central-European legal grower specialising in maximising the harvest potential of his plants. The AutoMazar’s were grown in large 30 litre airpots containing BioBizz coco mix and were grown under LED grow lights. The result was quite incredible, the AutoMazar’s grew large numbers of huge blooms. Results like these are some of the best you will see – most home growers dream of producing plants like these. All the photographs of AutoMazar come from LEDbuds special grow.

This was an unusual grow in many ways.
•Firstly, the AutoMazar’s produced an exceptionally heavy yield and really looked like Xmas trees at the end. It shows what is possible from premium quality auto genetics in good conditions. The plants were held up by a cane-support system to prevent them collapsing under their own weight. The 15-20 largest side blooms all grew to a really good size, this is key to delivering XXL harvests in home growing.
•Secondly, the AutoMazar’s were grown in 30 litre airpots filled with coco fibre, an unusual combination. Often we see airpots being used to great effect with compost rather than coco. Coco fibre is a naturally well aerated growing medium which produces good results even in traditional plant containers. So seeing 30 litre airpots combined with coco fibre grow medium was an unusual sight. Airpots are similar to traditional plant containers, but they have hundreds of airholes around the side to allow extra root oxygenation, and airpots have a dimpled inner surface which prevent roots from clinging to the side/bottom of the pot. In this grow LEDbud showed what a great combination coco, LED grow lights and airpots make.
•Thirdly, LEDbud used a 600W Helios 6 from ledhydroponics above each Dutch Passion AutoMazar, offering a huge amount of light for 20 hours of daily photosynthesis. We see an increasing number of home-growers using LED grow lights to produce great results.

Enjoy the photographs, the following comments and pictures are from LEDbud himself.

“I had 2 plants, I called them Mary and Jane. I had to cut Jane down on 100 days because of mold and got 343g dry. Mary was 107 days and 407g dry. They were grown in 30l air pots with BioBizz Coco-Mix and fed with Canna Terra Vega in veg and canna coco in bloom.
•Day 67-90: Atami Bloombastic at 1ml per litre, the P/K (Phosphorus/Potassium) ratio is 20/21 for Bloombastic.
•Day 90-102: Advanced Nutrients Overdrive at 2ml per litre and flushed for 5 days.
•Day 52 to 66 day: Canna PK13/14 was used at 1ml per litre
•Day 66: EC 2.2 and this increased to EC 2.6 on day 90

I also used Canna Rhizotonic (root stimulant) until day 80. Canna silica and Plant Magic Magne-Cal + was used on alternate feeds, the pH was 6.2 to 6.3 from start to finish.”

“For the first 52 days I used one Helios 6 over each plant, from day 40 I used an additional Photon Pro 84 as a side light, one for each plant. From day 52 until finish each plant had its own Super Helios 6 (600W power draw). AutoMazar was very easy to grow, they love extra light and extra feed.”

“This my first grow with air-pots, I think they are almost as good as DWC, but easier.

Roots were plentiful, I don’t think I will grow in DWC anymore. I recommend airpots and coco.”



everyone wants to grow like this

generous levels of bud production is an under statement

“AutoMazar is lovely smoke, a taste like haze with a lemon fruity smell, she has an ‘up’ buzz.

It smokes very nice, even after just 2 weeks drying. I have only been growing autos since Feb-2013, I tried growing a few autos and was going go back to growing photoperiod varieties. Then I tried Dutch passions Think Different and AutoXtreme, I was happy with the plants and I started this AutoMazar. Now I am an Auto convert, flowering at 20 hours a day they get 8 hours more light than photo varieties. You get a better yield in same grow time.”

Congratulations to LEDbud on two very special looking plants, it was also great to see large airpots used with coco fibre and LED, we like to see home growers experimenting with new ways to push cannabis genetics as far as they will go.

AutoColorado Cookies review in coco fibre with HPS and LED lights | Dutch Passion

This weeks grow review comes from Captain Beefheart who grew a great looking AutoColorado Cookies in coco fibre using a 400W HPS and a 200W power draw Skyline LED .  Nutrients were Canna coco nutrients, plus CalMag (calcium and magnesium) additive from vitalink.


AutoColorado Cookies is a feminized auto seed variety, the parent genetics came from Dutch Passion Blueberry and a very special Girl Scout Cookies line from Colorado.  Its a sweet tasting variety, with fruity aromas and is one of the strongest indica dominant auto genetics we have ever seen.  When grown in optimum conditions she is an XXL yielder of very tight, dense sticky buds.  The genetics on this variety come from stable and top quality parents, so the offspring is equally potent.  Multiple blooms form, each bloom can produce 20-30cm of buds.  This is a variety that can take a lot of light, the more the better, especially from week 5 onwards.



AutoColorado Cookies, easy to grow home grown cannabis

AutoColorado Cookies is indica dominant, with just enough sativa genes to allow the blooms to stretch far enough to allow for a good final plant size.  Hybridising the Blueberry and Girl Scout Cookies genetics produced a vigorously growing offspring.  The pictures from the grow show the AutoColorado Cookies has grown into a strong bushy plant with 20 or more blooms.  Final harvests tend to be well above average mainly because there are so many blooms which can form in good lighting conditions.  This variety also responds well to side light, its a variety that does well for beginners but can deliver very special results in the hands of expert growers who can carefully optimise grow room conditions and nutrients.


Fast growing varieties such as AutoColorado Cookies often benefit from Calcium/Magnesium supplements in addition to the normal nutrients.  Modern autos are often grown under 20 hours of daily light.  Dutch Passion autos are better quality than most, they can even take 24 hour light from seed to harvest, under these demanding conditions the plants never stop photosynthesising and this can sometimes require Calcium/Magnesium supplements.  Magnesium plays a critical role in photosynthesis and is a key mineral in chlorophyll.


Coco fibre has become extremely popular with autoflower growers, autos generally grow slightly faster and larger in coco than soil.  Auto’s grow particularly well with good levels of root aeration, coco fibre has an open structure that allows high levels of essential oxygen to reach the roots.  Many home growers get great results with airpots in combination with coco fibre.  For maximum growth rates in coco fibre consider putting an air-stone at the bottom of the plant container, the roots love the extra oxygenation and will respond with explosive growth.


This AutoColorado Cookie was grown in an 11 litre container, which contained 7 litres of coco fibre.  In mid bloom she was being fed twice a day, with 3.5 litres of feed solution each time.  In coco fibre with optimum conditions a good quality modern auto can grow almost at the same rates as it would in a hydroponic system.  But coco fibre is, for many home growers, a much easier system to work with than hydroponics systems – e.g. deep water culture.  Hydro systems such as DWC can place demanding requirements to carefully control pH, temperature, electrical conductivity (‘E.C.’) and various other issues.


THC-rich home grown cannabis using coco fibre

Growing THC-rich cannabis in coco fibre can be simple and easy.  In many cases its simply a 2-part feeding solution, Canna Coco is one of the most popular feed solutions and comes in a ‘Part A’ and ‘Part B’ solution.  Of course, there are plenty of supplemental coco feed materials but not all are absolutely necessary.  Perhaps the most useful additional feed supplements are a pK boost for bloom, and perhaps a Calcium/Magnesium supplement for fast growing autos that are being pushed hard under 20 hours (or 24 hours) of daily light.

Note how the AutoColorado Cookies produced a large framework and plenty of blooms.  Sometimes a large auto can take an extra couple of weeks to finish if the auto has taken the time to grow a big, branchy structure.  The extra time is required simply because the plant genetics are working overtime to produce the necessary biomass to fill every branch with resinous buds.  The last 2-3 weeks of an auto growth cycle is normally the time when bud and resin production has reached maximum.  Allowing the auto the extra time to fully ripen can be the difference between a large harvest and a very large harvest.  AutoColorado Cookies uses some of the latest USA genetics which were selected for the XL harvest potential.


Any home grower looking for an easy and predictable way to get fast XL harvests of strong cannabis should consider a top quality modern auto combined with coco fibre.  At Dutch Passion we see lots of customers become entirely self sufficient cannabis growers with minimum effort and complexity.

Hi-Tech COB LED Clusters

sh 64 x 3wAll models utilise an advanced 200W, Chip-On-Board [COB] technology, full spectrum cluster unit. This provides a huge power density and excellent spectrum blending across the grow area. These High performance Integrated LED’s are the centrepiece of our latest high power LED Grow Light, a next generation set-up providing high power and efficiency whilst greatly improving reliability

Integrated LED’s

Integrated LED’s are functionally the same as their traditional counterparts, but rather than individually cased LED’s they are miniaturized and combined into single, multiple-spectrum arrays. This brings considerable advantages in thermal dissipation, creating a positive effect on lifetime; reliability and allowing us produce lamps that enter the next power-factor.

The High Powered 3 Watt LED’s are carefully selected from LED Manufacturers such as Bridgelux, Cree and Epistar and thoroughly quality checked before leaving the factory

The spectrums we use are 440nm, 460nm, 630nm and 660nm, UVB & IR. Even though this spectrum is the currently the best we are always looking for new discoveries in fine tuning wavelengths and spectrums which could mean more newer spectrums may be available in the future. These units are fully upgradeable as well.

Heat Management

Helios Pro Heatsink – image

Whilst being hugely more efficient than other methods of turning energy into light, 100% efficiency is impossible. Therefore LED’s do generate some heat output and this needs to be adequately dispersed away from the LED chips themselves. Note also that LED’s spectral output is affected by the chip running temperature. The bottom line is : the better the heatsinking and thermal management, the better the long term stability and reliability of the LED grow light.

Each Helios module has the mixed array LED hand soldered onto a metal core printed circuit board [PCB], These are the best component boards you can get for LED’s, specifically designed and produced by our own team of engineers.

Mounted On top of these are dual core, double plated heat sinks for superior cooling.

The efficient heat transfer paste is also carefully selected and tested thoroughly for its best heat dissipation from the LED diode to Heatsink

The whole internal components & Heat sinks are kept cool by high speed quiet ball bearing fans.
The only slightly warm air that comes from this unit is generated from exhaust from inside the unit from the heat sinks which are designed to transfer heat away from the rear of the LED diodes themselves. The fronts of the lights are slightly warm to the touch. So heat generation is almost Zero. This also helps the

Residual Humidity inside the area.

From Germination to Flowering, this LED is very capable of creating BIG yields, Big dense flowers and fruit and has been proven over and over again.

Very quickly rising to the top of our hot list, the Skyline is a masive performer.  The combination of stealth-bomber looks and large surface area of powerful LED point sources set the scene and follow up with explosive results in the growing phase, huge flowering and unbelievable yields of rock solid sticky buds.  With the high yielding varieties, or anything for that matter, this lamp can really drive them beyond expectation.

Real-world results are important to us, and this lamp definately is a massive move in the right direction.  But of course we’ve also put the final setup through the usual barrage of tests to characterise its performance and give you the figures you’ll want to know.


! Liberty Haze Cannabis Seeds | Official Barneys Farm Site

Liberty Haze is a strain created from a crossing of G13 with a fast flowering ChemDawg 91. This strain has both Indica and Sativa characteristics, and has a fast flowering time of 8-9 weeks, where it grows to a medium height. This plant has a substantial girth, and performs excellently both indoors and outdoors. The long dense colas start to fatten up in the last few weeks, producing dense buds in a beautiful red and purple calyx. The buzz is immediate and long lasting, creating a euphoric cerebral effect. This strain has a distinct lime taste and fragrance. Lab tests rate the THC content at up to 25%.

The Ultimate & Helios 6 led grow lights


The Ultimate is one of Dutch Passions heaviest yielding varieties, she is a balanced 50% indica/50% sativa variety with a reputation for being easy and trouble free to grow. The Ultimate is also a customer favourite, the heavy yields are probably the main reason why repeat growers choose this variety.

This grow is with Evader 300w and Helios 6 led grow lights.

This weeks strain review comes from medical marijuana campaigner Clark French who is lobbying the UK Government to legalize cannabis for medical purposes. Clark recently formed the United Patients Alliance who are meeting with UK Government ministers in an attempt to change UK law. Here is his strain review.


LED grow lights runs cool and in last few weeks you can get light close to top of plants, love this led grow lights from ledhydroponics.

The following text comes from Clark:

“Appearance. Very elongated and huge bud formations. This bit (image below) is from one of those huge buds – quite dense with a very liberal covering of trichomes. Deep green leaf and a nice nearly lime green buds that have a hit of the foxtail calyx form. Loads of plumes of deep orange hairs erupt out of every calyx it looks really great.”


“Aroma. Has quite a limited palate in comparison to some other Dutch Passion strains before you break it up smells musky and earthy. Though this really changes after you grind it and a real sweet almost tropical fruit comes out in the high notes and those low earthy tones become much more pronounced.”


some final views on the smoke/vape quality:

“Effects. I like The Ultimate’s effects. It was great for smoking in sessions with my friends in social situations. Its not as effective as a CBD rich variety for my MS symptoms but I can definitely feel the difference. After medicating I can feel the pain and spasticity begin to go down and in general I feel better physically. The thing I think I liked most about the effect though is that it has a very calming feeling to it, I think that this would be a great strain for someone with anxiety as I do have problems with this from time to time and the ultimate sure feels like it would help in that situation. I haven’t had any anxiety problems for the short time I had a little of the ultimate in my life – this may be a coincidence or maybe because I was smoking it? who really knows.

Comments. Definitely a strain which I would like to try again – I’d like to keep a little then use it when I have problems with anxiety and really test how effective it is for me.”


Above and below: The blooms are heavy and long, adding up to harvests that are well above average


Thanks to Clark for the strain review/smoke review of The Ultimate.. Since The Ultimate is one of our customer favourites we also produce an automatic version, AutoUltimate, also a heavy yielder with a lemon taste.

Orange Hill Special & Photon 189 led grow lights

Orange Hill Special
Orange Hill Special is a recent traditional photoperiod variety from Dutch Passion. She was introduced following many years of requests from our customers for a new member of our ‘Orange’ family. Orange Hill is a cross of our famous 1980’s classics Orange Bud and Californian Orange and was stabilised over 6 generations of breeding. This is a really strong variety with THC levels of over 20% and a balanced indica/sativa effect. Orange Hill Special is one of our best received new photoperiod varieties, and because she is such an important variety we sell her in regular seeds as well as feminized. Regular cannabis seeds only account for 2-3% of our sales these days, meaning that we supply them as a service rather than as a business. But regular marijuana seeds are still important to many of our old-school customers and we remain committed to them.

The pictures and words in this weeks review come from Autoburry grown with Photon 189 led grow lights from ledhydroponics.

Comments from the grower: “It was a superb journey with the Orange Hill Special, the average yield was 117g dry. The 109 day grow period is inclusive of 12 days flush with pure reverse osmosis (RO) water, since RO removes salts much better than tap water. The average height was 1.3 metres from soil at 109 days. The tallest in range, was 1.6m. I found the Orange Hill Special a pleasure to grow, the germination rate was 9 out of 10 within 8 days. They were very vigorous in 18/6 light, more so in 12/12”

Used Photon 189 led grow lights on full power from start of grow.

“Smoke Report: 21% THC, wow its a superb melodic, sativa-creeper cerebral, serotonin, thinkers high. The high lasts 3hrs+ before dying back to a post-steak meal satisfaction. This fills your chest cavity. The bouquet, when re-entering the room, is of the old school ‘Orange’, that Bulldog coffee shop perfume of 1990’s Amsterdam”

oranghill 6






















Here are some final remarks from bugger

“Its a 50% Sativa 50% Indica, with 21% THC, cured out to the max. This gives me a balanced stone. Sativa head dominance is balanced out with indica which comes through in the satisfaction with a calm psychoactive trait of the sativa lineage. This one delivers the bouquet and flavor of zesty citrus of pungent Seville Oranges, with tropicana overtones and very sticky. To smoke, its like smoking “Orange Hash”. The trichome loading, as mentioned, is thick & heavy. Some colas were still bent over even though they where supported with 10mm canes.”

“All in all, a top bit of ‘Orange’ from this Dutch dame. Orange Hill Special, and special she is, for Orange Lovers. For new growers, it is a trouble free journey to the harvest fruits. But start on medium strength nutrients, then work up to around EC 1.2-1.4 in flower. Leaf tip color change happened above 1.2 in flower, in veg no issues where found at 0.9 Ec.”









Orange Hill Special is the first new member of our original Orange family for 2 decades. She is so good we made her available in feminized and regular seeds, she comes with our highest recommendations. If you are looking for a top quality photoperiod variety with the original legendary orange-family heritage then look no further. Orange Hill Special is

Photon pro power switches

Each Photon Pro lamp has its own power switches on the unit. This allows you to switch the lamp on and off in a convenient way but also provides a useful feature – As there are two swtiches, each controls half of the clusters so you can run the unit in half power mode when plants are younger and need less light, and change it easily to full power mode as you need.

Its a great way to avoid overkill with young plants as beyond some threshold, throwing too much light at them is both wasteful and non-productive. Save energy and take control with Photon Pro!

The Ultimate

The Ultimate & Super Helios 6 led grow lights

The Ultimate is one of Dutch Passions heaviest yielding photoperiod varieties on a par with varieties such as Power Plant and OutLaw.  It’s also one of the strongest and most potent varieties in our collection.  Not surprisingly it’s an established customer favourite with many repeat growers and a solid reputation amongst home growers.

blooms as thick as your forearm

The Ultimate is a balanced 50% indica, 50% sativa variety.  It gives a fast hitting high thanks to the indica component.  Those that do not have a high tolerance to cannabis should note that this is a strong high which continues to climb in intensity.  Even experienced smokers have been caught out by the strength of this variety, this is definitely not a day time smoke.  It has a strong cerebral and physical effect, its a great variety for relaxing or for medical use.  The variety was discovered by Dutch Passion several years ago after we came across a unique phenotype that delivered special quality levels combined with great production, taste, aroma and resin levels.  The original parent genetics were never disclosed, partly because we wanted The Ultimate to be recognised as a variety in her own right.

If you want to grow your own cannabis easily then this is a variety which comes with our best recommendations.  Not only is ‘The Ultimate’ one of our best yielding varieties but it is also an easy variety to grow and produces exceptionally strong cannabis with a long lasting high.  The pictures and comments of The Ultimate this week come from LEDbud, a European home-grower who specialises in growing under LED, he uses lights from Quantum LED.

bulging blooms


dense nuggets

Here are a few comments from LEDbud, who has also grown our AutoMazar with great results.

“This variety is fast growing for both veg and flower.  During flowering this variety initially didn’t seem too fast, but within a couple of weeks she was producing large amounts of flowers all over.  The buds kept filling out and didn’t know when to stop, this was the only time I have seen a variety behave in this way.  In the end I chopped the plants down, but I could have just left them to see how big they could have got.  However the plants were already collapsing under their own weight and I didn’t want to risk leaving them to fall over”

blooms everywhere

LEDbud continues his description of the grow:

I been growing with LED grow lights for few years and i change fron HPS to led grow lights because HPS was getting to hot in summer months, with led grow lights i can grow even in the hot summer months.
also in last few weeks of grow i can use more led grow lights and my plants love it.

“I used  Canna Terra Vega & Flores from Canna Nutrients.  Atami Bloombastic helped maximise harvest weight.  I used Budlink Silica to help with plant growth as well as a Calcium/Magnesium supplement and Overdrive from Advanced Nutrients.  In the end I averaged over 130g per plant without any real problems or difficulty.  The buds were great looking, a combination of heavy trichome production and red hairs reminded me of some old school skunk that blew my head off in a Dutch coffeeshop back in the 90’s.”

rich resin layers
a home growers dream

LEDbud concludes with his views on the smoke quality.  “The smell is sweet and fruity, however it’s a very strong aroma in the last 4 weeks, anyone thinking of growing this variety should make sure that their carbon filter is working well.  The taste is similar to the aroma, very skunky but sweet as well.  The best part of this variety is the high – POTENT!  It’s strong and powerful in the head, watch out.  For me its an energising and creative ‘up’ buzz.  The plants were grown under 2xQuantum Photon 189 and 2x Photon 84 which produced uniform and dense nugs.”

The Ultimate is something of a favourite variety of ours, so we are biased, but this is a really special photoperiod variety which generates a lot of great feedback from very happy customers.  If you want to grow your own weed easily, if you want quality without compromising quality then The Ultimate is one variety which you should definitely try yourself.

Desfrán is a new pure sativa variety based on the award winning ‘Destroyer’ genetics which have been so popular in South America in recent years.  The Dutch Passion version is a specially selected cross of Destroyer x Destroyer, this is one of the most resinous varieties we have seen and will be highly appreciated by the sativa lovers.


Desfrán is a stretchy variety which may try to outgrow the space in your grow room, watch out if you have limited space, or consider growing this in a SCROG system to keep the stretch under control.  The word and pictures in this weeks blog comes from Automaster,

Automaster starts by explaining some basics about the Desfrán grow.

I grow in seedling soil with added lime-free sand perlite & vermiculite and a small amount of coco fibre to aid drainage.  My main light is Photon 189 LED grow lights..  from ledhydroponics, on average  used 350-360W of  power   I used Greenair genesis 3 part nutrients, air extraction gave 15-20 changes of air in my grow room each hour.”

“The Desfrán is truly a light feeder, by that i mean, she also drinks low volumes and does not need high nutrient levels. I watered every day discrete amounts up to 500-600ml per day. She makes the best of a small amount of nutrient, she does not need a great deal to get full bud production going. High sativa’s such as this strain are light feeders and drinkers, and the Desfrán especially so.”

“Desfrán has a wide heat tolerance – I noticed that the stoma on the leaves did not close even at 31-33c…….in fact she thrived. My ‘lights-out’ temp averaged at 21-22ºC, the same as the soil temperature. You will need to support the Desfrán with at least 4 long canes per 15 litre pot because the blooms are long and heavy.


Above and below.  The long heavy resinous blooms make Desfrán a good yielder.  Growers should note that this variety can easily reach 2 metres+ and needs a tall growroom.  Watch out for stretch.

Automaster adds more about the growth of Desfrán:

“Do not let the Desfrán sit in soil which is too wet, she will not like it because it blocks oxygen and gases getting in and out. I used ‘RootGrow’ Mychorrhizal root fungi beneficiary granules at root base, this helps healthy root formation with rhizotonic fed separately from reservoir.  The starting pH was 6.2 rising to pH 6.8 at the end of bloom.  Water was RO (reverse osmosis) which was allowed to stand for 36-48hr before use.”


Automaster has two main tips to future growers.  Use tall canes to support the long blooms and use minimum amounts of water and nutrients.

“To future growers I recommend you use 2.5m canes, I used around 10-15 ties per plant (using string) to keep it as upright as possible.  On the lower part of the plant, cut off any small branches, this redirects the energy into the main plant.  Controlling stretch is important, I tried every trick I know to control stretch, including low nitrogen in veg, and even nitrogen lower in flower. I managed to limit the stretch to the 6 to 6.8 feet (2-2.5 meters) at end of flower.

Some closing remarks from the grower

I had a first smoke test after 8 day’s in air tight cure at RH 62.5%  at 8 day’s it is the strongest delta 9 I have ever had. I could not finish the first few smokes of a 0.5g joint.  As it hits the chest a delicate envelope of euphoria envelopes you, like a warm late Autumn breeze,  animated, exhilarated, elated   All whilst trying to remember to breathe……… think i put to much in the joint !!  Desfrán is everything a good sativa should be,euphoric, moving to utopia and then the CBD & Bichromenes kick in and your gone.  Great quality sleep follows with a feeling of well being in the morning. The aroma is complex to say the least, but, a cross between a super crystal hashish and a Tropicana refresher candy chew.  The deepest, fruitiest, soothing floral, thickest, richest, most intriguing, rewarding bouquet of a sativa i have yet to cultivate…………. goes into my top 5.

Photon Pro 189: 567W LED Grow Light


Critical Jack Auto & Chronic Ryder under helios led grow lights


this grow is by ledhydroponics customer teetee.
Lights are 2 X Helios 2 & 1 x Helios 6
grand total from harvest was 19.4 ounces
Welcome to my latest grow, 3 plants in total, just as a test grow before I grow some Dutch Passion Auto strains, and then perhaps some Southern Star regulars in the New Year.

There’s a bag of buds on the table over there, knock one up, and come have a look at my set up….

I’m growing in a 1.4m x 1.4m tent with 6″ air exhaust and 4″ intake, running 24/7… no carbon filters yet.
I feed them the House and Garden Coco 2 part nutrients with the full range of H&G additives, and they have 1x Helios 6 and 2x Helios 2’s, 28″ above the plants on a 18/6 schedule.

The plants:-
2 x Critical Jack Auto – This strain by Dinafem has genetics from all sorts… Critical Mass, Jack Herer, Shiva Shunk, Northern Lights #5, O Haze and Lowryder. It is a high CDB strain, and takes 70 days from seedling to harvest. It reaches up to 2 or 3 feet high under appropriate conditions, with lots of light, warm temperature, and an aired substrate. But it doesn´t grow much if the conditions are not perfect, yet quality is always good. The quality of the final product is what makes the difference from less enhanced strains. I should look forward to hard tight buds, strong odours, completely covered with resin, and intense sweet flavour, with hints of lemon and frankincense.

1 x Chronic Ryder Auto – This is another strain from the Joint Doctor… a cross of Lowryder #2 and Chronic, taking 65 days to harvest. It can pack on a lot of weight due to its dense, prolific budding, producing very large, resinous nuggets with 12-14% THC.

I planted the seeds direct in 100% Coco each in a 22L airpot, covered them with clingfilm, and 3 days later they germinated and popped their little heads through. I gave them a 0.6EC feed and the next day 0.7.

They stayed on 0.7EC till day 6, and on day 7, I upped the EC to 0.8, which they stayed on until day 9. Today on day 10, I have increased the EC to 0.9.

As well as the H&G Coco nutes. they are getting the following H&G additives….

Drip Clean 0.1ml/L
Roots Excelurator 0.2ml/L
Amino Treatment 0.1ml/L
Nitrogen 27% Boost 0.1ml/L



Helios led grow lights

….plus they get a little CalMag (I use 0.1ml/L as an additional buffer in my 0.2EC tap water), and I use Silicon as a pH up. The plants also receive silicon from the Amino Extract, and I understand the Coco is enhanced with CalMag as well as being buffered.

I hand water them 0.5L pH 5.8, 3-4 times a day to get a semi-hydroponic effect, and they seem to be lapping it up…
I chopped the Chronic Ryder on he 30th Dec, but I was taking buds off from her from 26th Dec. The decarboxylation worked great… I know it’s a sin to use buds before proper drying and curing, but we just cannot score very easily at the moment, and the smoke is good, so why not? Both strains are good, but I mainly stole from the Chronic Ryder, simply because she had been flushing for longer. No cracking, no choking my guts up… nice and smooth! Looking at the trichs with a USB microscope is easy, and I saw all trichomes had gone proper milky. I didn’t see many ambers, but I realise this is a strain specific finding, and I believe a lot of other growers’ ‘amber’ trichs are actually brown trichs that show the THC is degrading. Very milky is good for me, and the curing process will make the most of the cannabinoids. Already she’s a strong, clean smoke, but when cured…. mmmm I can’t wait!

Lights are 2 x Helios 2 & 1 Helios 6 FROM LEDHYDROPONICS
I like to manicure my buds when wet, so I remove all leaves, keeping the trich laden sweetleaf aside for making either cannabutter or bubblehash…. that’s all bagged and in the freezer…. waiting for the landlord to piss off so we can get cooking one night soon.

The buds were sorted according to size and brown paper bagged for 6-7 days until they reach a stable RH of 65%. Towards the end of the 6-7 days, I put them in glass jars for a few hours, to even out the humidity within the buds, and then brown paper bagging them if the RH rose from 65 to say 70ish. Slowly but surely I get them to 65% stable, checking with a Caliber III cigar hygrometer, and ‘burping’ the bags or jars one or two times a day.

Once at stable 65%, I put the buds in some Violet glass screw top jars, with a Boveda 62 humidipak added to bring the RH down to 62% and leave them for a further 2 weeks to cure.

The Chronic Ryder is almost at the curing stage, most bags are stable at 65%, one or two are still a few days away. Dry weight is 100.5g, and I estimate we smoke around an ounce a week (approx 28g), and we’ve been smoking her for a week and a half so lets say the total dry weight was around a conservative 140g… just under 5 ounces! I’m well stoked.

The Critical Jack 2 had a massive harvest, so I decided to keep the large buds and cola intact and hang them upside down in a cardboard box to slow the initial drying process down a little. I have about 30 big tops drying this way, and about 10 brown paper bags with manicured buds in them. The buds are really hashy and sticky 😀 I think she might give me well over 7 ounces all in all.

Critical Jack 1 is on her own now, and she has the whole tent to spread out in now, so I have tied down and pulled apart her branches to get the most light…. she will probably give me over 5-6 ounces as well by the look of it. She still needs a couple more weeks though.

I’m now gonna roll a nice home grown spliff, and I’m gonna add some of that lovely scissor hash that I patiently gathered during the chop….. yum…. everyone’s asleep or occupied, and I have the day off!

I’m gonna plant some more seeds this week. Probably 3 Blue AutoMazars, or I might do 2 BAM’s and one Auto Think Different.
I don’t see the point of growing anymore than 3 plants in this tent, there’s room for 4 but space gets really tight during flowering, potentially reducing the yield for each plant. I believe the tent size plays a bigger part in determining the final yield, not the number of plants.



Anyways, here’s some pics from the final few weeks…..
So the Critical Jack 2 finally dried and is curing now….. the RH of the bud is now at 62% and is Kilner jarred with Boveda 62 packs, stashed away for a while.

Final weight is 173.49g, which is approx 6.12 ounces.
In total the Critical jack 1 gave 8.8oz, Critical Jack 2 gave 6.1oz Chronic Ryder 4.5oz, making a grand total of 19.4 ounces….. that should be enough for me and the Missus to use till the next crop, as we get through an o a week, maybe more now that we are elbow deep in the stuff.

I’m so glad we don’t have to drive 3 hours to score $1000 worth of chokey, un-flushed bud every 3 weeks, risking my family and career getting busted by a nosey traffic cop.

Thanks to everyone who came to visit, and I hope you enjoyed the grow as much as I did.

Thanks also to M and the team at LED Hydroponics, I can honestly say these lights do the job perfectly, I have no affiliation to the company, so this is an independent grow.

LED Lights Used in Plant Growth Experiments for Deep Space Missions

What kind of food will astronauts eat and what is the best way to grow it during deep space exploration missions? A group of plant biologists is seeking the answers as it works on one of NASA’s Advanced Exploration Systems (AES) Habitation Projects at Kennedy Space Center’s Space Life Sciences Laboratory, one in a series of projects taking place at the agency to forge new approaches to rapidly develop prototype systems, demonstrate key capabilities and validate operational concepts for future human missions beyond Earth orbit.

Gioia Massa, a NASA Postdoctoral Fellow in the Surface Systems group of Kennedy’s Engineering Directorate who works on this AES habitation-related project, said they looked at the responses of a red leaf lettuce called “Outredgeous” and radish plants to different light sources—broad spectrum fluorescent lighting and solid state red and blue LED lighting.

“LED lights are efficient and versatile,” Massa said. “Because of their durability and long life, they are ideal for space missions where resupply of things from Earth is limited.”

According to Dr. Ray Wheeler, lead for advanced life support activities in the Engineering Directorate, using LED lights to grow plants was an idea that originated with NASA as far back as the late 1980s.

Some of the first NASA-funded tests were done at the University of Wisconsin and at Kennedy using wheat and just red LEDs. Wheeler said the wheat plants were very leggy and almost bleached out.

“Blue LEDs weren’t very good back then, so using blue fluorescent lights helped correct those problems,” Wheeler said. “Today’s LEDs have vastly improved in their efficiency.”

Dr. Matthew Mickens, a graduate of North Carolina Agricultural and Technical State University and recipient of the NASA-sponsored Harriett G. Jenkins Predoctoral Fellowship, followed the plants’ growth during his tenure at the center.

During a recent harvest of the plants, Mickens measured the plants’ shoot length, the shoot diameter, total fresh mass or the weight of the plants at time of harvest, total dry mass of the edible plant matter accumulated during the growth cycle, and the leaf area index.

He used a chlorophyll meter to measure chlorophyll content. Then Mickens flash-froze some of the plants in liquid nitrogen and ground them to a powder in order to perform a new test, an adenosine triphosphate analysis, which measures stored energy in the plant tissue.

“One of the objectives of the study was to understand the effects of green light on plant growth,” Mickens said.

For the test, he compared the growth responses of the lettuce and radishes grown under a treatment of red and blue LEDs, and a treatment of broad spectrum white fluorescent lamps with green light present.

“I discovered that there were considerable physiological differences between the two treatments,” Mickens said.

According to Mickens, results showed darker red color under the red and blue LEDs, which indicates a higher concentration of anthocyanin, a powerful antioxidant that can combat some of the effects of cosmic radiation. Additional replications of the crop cycles are currently ongoing to further confirm these observations.

“Even subtle changes in light quality can potentially increase antioxidant properties of crops such as the lettuce used here,” Mickens said. “The nutritional quality of the vegetables meant to feed our astronaut explorers can be controlled by proper selection of lighting used to grow these crops during long range space missions beyond low Earth orbit.”

There is evidence that supports fresh foods, such as tomatoes, blueberries and red lettuce are a good source of antioxidants, according to Wheeler.

“How they are grown and then consumed in space could have a positive impact on people’s moods and could protect against radiation in closed environments,” Wheeler said.

“As we learn more about different light sources we can better configure the lights to more efficiently product plants that will produce food for the crew, recycle the atmosphere and help to recycle water,” Massa said.

“Ultimately, we would like to develop closed-loop bioregenerative technologies that are self-sustaining,” Massa said. “Our current supplemental food production system is a step towards this future goal.”

blackjack auto & Photon 84 led grow lights from ledhydroponics

blackjack auto Hi all, I’d like to share with you all this fantastic Auto Grow one of my test growers had completed with this fantastic LED from LEDHydroponics, Heres the LED used; Photon Pro 84 http://www.ledhydroponics.co.uk/photonpro84.html And now for the setup; 50x50x180 cm Stealth Drobe Large Diamond Point Mylar Interior Seedling in 1L Airpot first Then moved into 20 L Airpot BioBizz Medium Mix Soil BioBizz Grow & Bloom Feeds 1 Ml of BioBizz Grow per Litre of Water was used throughout the grow Bloom was adjusted according to the BioBizz Feeding chart throughout the grow. Seed : Black Jack Automatic from Sweet Seeds This was run under a 20/4 Schedule. Chopping her on Day 77. Main reason for chopping her at this stage is Over 90% of Trichomes are now Milky, as I wanted to get the THC at peak levels & hardly any CBN CBD will remain at constant levels through-out plant degradation but THC will degrade into CBN, which will taint the effects of true CBD. All in all, 145 Gr Dry. (with the popcorn aswell) Not bad for a little cab grow. Wicked little light aswell love this lights from ledhydroponics. My test grower had no problems whatsoever with it. Fans kept nice and quiet throughout. Unit kept nice and cool in that small area.



  1. I am growing over 24 years and always use sodium and metalhelid to grow lovely big buds.
    every summer I stop growing for 3 months but this year my friend got me into led from ledhydroponics.co.uk.
    and this lights fucking works. managed with ok and buds was not bad.
    I an going try this led in winter to see how they do.
    I will say they worth it even if just for 3 months in summer.
    I will update how they grow in winter.

  2. I got skyline 800w you told me they use 400w.
    that what you recommended to replace my gavita 600w.
    i might buy few more next month, just waiting see what i get from this grow.
    they looking ok but wont know till i take them down and see what weight i get.

    • they my best led grow lights mate and yes they only use 400w electricity.
      email me when you want more and i give you discount.
      happy growing karma.

  3. Admin
    what discount if i want buy 4 units skyline 400w.
    this just for test if it works i will buy 20 more units.
    thanks in advance.

  4. Hi
    i got 2 led grow lights and the fans are so loud but you say your led are silent.
    i have to change better quality fans but they still loud. how is your led silent.
    my wife hates noise they make, they keep her up at night.
    i will buy if your fans are silent.

    • Hi Tim
      most led grow lights has fans and when you got few led grow lights in one room they are loud.
      at ledhydroponics we have led grow lights with out fans so they are silent.
      we use loads heat-sink to replace fans. the new Skyline series LED Grow lights Silent & Powerful. Waterproof & Modular. Built to last the wars. The Skyline grow lights are the latest development from LEDHydroponics.co.uk. Bringing together the best in high-tech materials and LED chips to deliver a new range of modular LED grow light systems. Each module has a blend of LED types (CREE XTE) to create a powerful spectrum that at the bottom-line does wonders in the grow room.
      you wife will get good nights sleep with this led.

  5. was looking for led grow light for 1.2 x 1.2m tent, what light will you recommend.
    I want something that works in growing and flowering.
    I bought mars hydro led but not happy with them, my friend has use your lights and he loves them.
    I also like your youtube videos and how dose your 90 days money back works.
    thanks in advance.

    • hi James
      you can go with skyline 800w that only use 400w or super Helios 6 use 600w.
      skyline 800w is a cost a bit more as it is waterproof and has no fans.
      its silent and has more heat sink, its about 12kg.
      if money not problem i will go with skyline 800w you also save 200w power compare to super Helios 6.
      they bought work.
      the 90 days money back, if you return your lights within 90 days we will refund 80% money.

  6. Hi
    good information on led and weed plants.
    I am new to growing and glad I found this website.
    do you ship to USA and if so how much will it cost.
    I just want grow 4 small plants so what is best led grow light for me.
    was going buy 4x4x6ft tent.

  7. Keep up the excellent work, I read few articles
    on this site and I believe that your site is rattling interesting and holds bands of great info.
    i will be getting skyline end of this month.

  8. I have used skyline 400w and actual power used was 210w and I got back 328 grams dry buds.
    that better them my old HPS 400w. that over 1.5grams per watt used.
    finally led that work and not having fans is a added bonus. I going get 1 more after charismas.
    thanks for all your help and advice Muddy, you are absolutely mint mate.

    • Hi Adam
      glad you like the skyline 400w, i have many happy customers. the Cree led is amazing.
      just email or call when you ready to buy your next unit, i will work out discount for you.

  9. Quality bit of kit
    My new Skyline 800w has just been delivered. First impressions: This is a sturdy, well manufactured unit. Meanwell HLG-240H-36A drivers, Cree XT-E, passive cooling. All cabling, connectors and fasteners are of a high quality. Extremely robust frame. If I dropped my old MarsHydro reflector 192, it would likely be in multiple pieces and non operational. This would put a hole in the floor. Obviously can’t comment on how it performs, I’ll get back to you on that..
