I have heard from friends, and read about, a technique that is supposed to stress the plants in a way that they produce more crystals, like the maximum amount, but im not sure if it works. They said to turn the light either off completely or down to 8 hours on instead of 12 durring the last week or two of flowering, then I met a guy who said he shuts the light off the last 3 days before harvest... does anyone have some insight into this? anyone practice this technique or any variation? Does it really add resin?
