i havnt grown since last season, but if i remember right, the dark is the time they use for maturing and "growing". were the light is the time when they get all there energy.

so if that is correct, the 4 hours might shock them.

were the 36 hours of darkness will just let them mature a littlemore.

((also, dont forget to flush a week or 2 before. you look very close to harvest )) :hippy:
