really need a controlled study on it to really find out if true or not. like clones from same plant, then EVERYTHING the same till chop, except for the splitting of course. I do it, but my grows usually have something wrong with them to notice really, lol..
Brain storming in the past about it, you have to think, the reason is for more resin, so I think the best way to get the most would be to do 3 days before 48 hours darkness, and Low light intensity, maybe 25% of your flowering watts. Heat and light destroy the trics, and Ive seen more frost in lower light conditions, ala bottom buds furthest away from light, then top colas that bathe in the light. So, at this point, we are trying to protect the trics from melting off and getting light damage. So keep that idea in mind if you try it.
Not saying it the best way to do it, because i dont know really, but the thought is, Build more frost, and protect it from excessive heat and light. Also, during the last 3 days before the 48 hour darkness, Use 5000K if at all possible, or the highest K value u have. On my final week before chop, I use just my 4000K, but looking to upgrade to higher value in the near future, just to finish off the buds before chopping.
Just some input for the thread, food for thought.
