Ready or not....

I have 2 lemon skunk plants year have been on 12/12 flowering since 1st May, (approx 9weeks), I also have some cheese in tent that ain't ready, if I leave my light off for 20 hours before taking my lemons out then my cheese plants will still be OK, they won't hermie will they?

You're rollin the dice if you do, I wouldn't do it. You're gonna have to get creative and figure out a way to get the girls in the dark, if you feel that it is really necessary. Perhaps relocate them...if you can.

Wby do you want to leave your light off?
