I think rhizome is saying that if you do the light trick, you may be able to spot males a couple days earlier than normal, and you do this at the cost of a slightly smaller yield. So... are you trying to weed out males? If not, then there is no need. Just go to 12/12.
Opie Yutts Reviewed by Opie Yutts on . first 3 days of 12/12 ive read that for the first 3 days of your 12/12 cycle that you should give the plant 3 days of complete darkness before re introducing light. this somehow sets the internal clock of the plant to let it know to start flowering more efficiently or something. does anyone know?
