I have tried that, and found that a 10/14 light schedule did in fact speed up the finish of the plants, but I am uncertain what this did to the overall quality and potency of the product. I am attempting the opposite this time, and instead of running less hours of light, I am running more (13.5/10.5) and with so little darkness that they are in danger of reverting back to veg. More light per day would logically seem to be advantageous, but few have tried it, because it doesn't work without the accompanying trigger lights. I presently have 6 different varieties involved in this experiment, and so far it looks like flowering is being accelerated. The true test for me is going to be a very well known and often run strain, the White Widows. They consistently finish in 8 weeks to the point that they could be harvested, and typically running them for 9 or 10 weeks provides for a very impressive and extremely frosty finish. I am waiting to see if anything new happens in those last weeks since I have already seen advanced bud formation and development in these plants as a result of the lights. The questions will be how to interpret what we are seeing during this grow, so that a proper White Paper can be written at the end of this, documenting the results.
Deeewwwwwd....! You`re kicking a$$ vis a vis these overview articles! Two thumbs up.. hope you and yours are well @danishoes21, the xenomorphs too. I recommend to everyone who is a fan of growers who elicit body-horror tropes as a part of their horticultural repertoire to check out your journal. Why a cannabis company has not snapped you up is beyond me, but that`s me assuming you`d want such a job.If I understood correctly two stages of flowering take place; the flower initiation where the plant structures itself to build flowers (this stage needs a certain demand in photoperiod and photon flux) and once the flower is set, stablished and grown the second stage takes place; flower or fruit ripening (this stage needs a certain demand in photoperiod and photon flux).
If you have time to read this, its very science based.

Thank you sweetie! I am indeed enjoying this!Good morning Emmybird
Congratulations on the winS.
You deserve the accolades. You put so much time and work into both your teachings and your journal.
Congratulations.
I’m super proud of you.

Thank you Love for both the nomination and your congrats! I kept thinking that there was no way the folks would let me win 2 major awards in the same month and I was surprised at the end. I was convinced that the competition would stage a rally for the finish!Congrats on your duo wins, Emilya! I'm especially happy about the GJOTM win since I'm one of the people who nominated it.
Which plant has the big colas?Veg Room 1
This room is now empty except for the Dynomyco experiment, being covered in a dedicated thread, click here.
Veg Room 2
The Tangies got fed and watered yesterday after going way too long between waterings, but I needed them to reach for the bottoms of these tall containers. The plants have become massive and I am glad there are only 3 of them going over to bloom in 10 days.
Bloom Room
This room amazes me every time I open the door. The White Widows are doing that foxtailing thing that they do when the buds start expanding out horizontally, and as a result these buds continue to get bigger, taller and fatter. I am not hurrying this harvest, despite what it is doing to my room rotation, and I fully intend to let these Widows go for 9-10 weeks for full trichome coverage. This of course is under normal lighting, and so far I don't even have a guess what these are going to do, other than I am putting a small wager on them finishing a week earlier than they normally would, due to the lighting pattern.
In the new bloom section, I think we are done with stretch now at day 15, with two of the plants growing right up to several inches away from the light. I have seen several plants over time get this close to the big @NextLight MEGA, and I am always amazed as bright as it is, that the buds don't burn up here. Nevertheless, I moved the light up a few inches just to be cautious. Ghost Train Haze and Strawberry Lemonade have both taken the lead in the stretching, at 34" above the soil. The other strains held back quite a bit, and I will get the percentages of total stretch in a future posting, but these two came very close to 100% stretch. Since these are unknown varieties in my garden, I don't know how much they would have stretched natively, without the trigger lights, but I suspect that both of these girls could get very tall if not carefully managed, but as a result I can not tell if the red lights had much of an effect in keeping them short this time. Looking at the height of the other new plants, I tend to think that the lights are indeed effective... but maybe not so much on all strains. More experiments need to be done, but I am still convinced that the trigger lights are effective to a point, but in these strains that seem intent on producing foot long colas, maybe there is nothing we can do about that other than enjoy the outcomes of their genetic inclinations. At any rate, even at 34 inches, the plants will be perfectly safe in my 6'6" attic grow room, with plenty of room to spare.
In the older plants? The white widows for sure..
Variety | Original Height in inches | Height after 16 days | Percentage of Stretch |
| Green Crack | 16 | 31 | 112% |
| Ghost Train Haze | 18 | 34 | 88% |
| HulkBerry | 19 | 30 | 58% |
| Strawberry Lemonade | 18.5 | 33 | 78% |
I consider supercropping to be a last ditch effort to fit vertically into the grow space. Sometimes its the only thing to do, when that one aggressive plant stretches to nearly 3x its veg height. Sativas are known also for their dramatic stretch and are problematic for me in my 6'6" ceiling height. Since using these rooms I have only had to supercrop two plants, but it seems there are times when it is necessary.
