When I have to adjust my schedule like that, I give them a little extra dark, instead of a little extra light. My thinking is: if you give them too much light, you can set them on the road to re-vegging, which, if they're flowering, you probably don't want to do. A little too much darkness won't ever send them on the path to re-vegging.

I also had a power outtage for nearly 3 days, and they got virtually no light during that time. (I used flashlights, to hopefully make them think it was daylight, and basically just keep them on their established schedule.) Surprisingly, after almost 3 days of high heat (peaked at 99.5 degrees F), no ventilation, and virtually no light, they had sustained very little damage. Cannabis plants are actually more durable and tough than I had thought.
jamstigator Reviewed by jamstigator on . question about 12/12 so my timer is busted and i havent been able to get a new one because iv been sick and iv just been switching by hand. i turn them off around 830 in the morning and turn them back on at 830 at night. tomorrow night i have to leave my house at 8 do you think it would be better to let them get 11and a half hours of dark or 12 hours or dark and 11 and a half of light. and then will it be ok butting tham back to 830 again after that?
