Hey guys, so this is my first grow and I had a question about dark periods before harvest. My plant has been in the dark for 36 hours now, and sometime between now and Thursday morning I'm gonna harvest. How long is the longest I can leave my plant in pitch black? I've heard a lot of people say the most you can do this form without stressing the plant too much is 48 hours, if so I should harvest tonight. Anyone?

The reason I'm trying to leave the plant in pitch black is because I need to be able to leave town friday morning. I gave my plants a 10 week period to flower, but unfortunately my ak-48s didn't like the cfls too much, I only had 100 watts total, and the plant still needs another week probably.

Awesome, thanks blade.does anybody know what the limiting factor is for leaving a plant in the dark? Stored energy?

As far as i'm aware the plant will put all its energy into the flowers/buds in prolonged darkness which is why i allways do this for 2-3 days before harvest. Not sure on the herme thing. Sorry.

Good luck
