Not a secret. And not the choice of real growers anywhere....The whole idea and the spreading of this crap,,,makes my head hurt - Just like mackdx.
Run your veg at 24/0, You should have a 24 dark period before flipping, and don't forget to defoliate. Then 48 hrs of darkness before harvest and don't forget to use molasses in your flush, or just molasses with your feed for the last weeks....I'm sure I left some other wonderful questionable to down right BS things out. So feel free to try Mountain Dew on them and don't forget the spooge foliar! Like when a worker was picking his nose in the old op. "Hey, Jeff! You know what? Put that under the leaves at the top of the plant. That'll keep mites and molds away!" He looked at his finger and then the plant and said, "Your kidding, right?"
