Purple Punch: The New Beginning

Don't worry about what week, what is written on the packets usually resembles fairy tales and not real life. Start a 7-10 day flush once your plant has about 95% brown pistils and harvest when there are around 98% brown pitils. This will put you in the "10-30% amber" zone without having to look too hard and give you buds with peak THC levels. Hope this helps, Organoman.

Don't do the darkness thing, it is BS. A plant in extended darkness will have an almost stopped metabolism, meaning there will not be enough metabolic activity to prevent THC breaking down. The whole myth is rubbish, it is not repeatable, does not work on every strain and was ONE flawed experiment that due to the magic of the internet turned into ghetto science and a supposed "fact", which it clearly isn't. 2 days without water is plenty, and this is another myth, it is botanically impossible to super boost THC levels by witholding water. THC levels are controlled by genetics and genetics only. There is no way to get a plant to produce more THC than its genetic map will allow. Through experiments that I have done over the last 35+ years, I believe the best time to harvest is an hour or two after sun up/lights on and with everything else being absolutely normal, no stress, no darkness, no extended thirstiness, nothing. This seems to produce the tastiest buds and with the highest amount of terpenes too. You want the plant to be as happy and as normal as possible, then whamo - chop it down before it knows what is going on. Why anybody would purposefully stress their plants with strange "techniques" after months of careful growing and right before harvest, is beyond my comprehension! Hope this helps, Organoman.
