I was wonder what I should do. I left my lights on overnight by accident. im in my third week of flowering. how will this affect my flowering cycle. will it reset? should I leave the lights off for an extened time say 36 hours?...please help. thx
Just adjust your lights back to 12/12. At the worst you may have added a few days to your flowering time, but it won't ruin you.
No doubt. I wouldn't chance it. If you mess with flowering light cycles you are taking a big chance of getting a hermie plant which sucks.
I've had plants go hermi, gods, not fun. Can laugh about it now, but back then I was so pissed off! Lol. Due to heat stress, AC broke in my house, took 3 days before I could fix it. Had temps of 95F some times.
I luck out with my climate, as long as I've got a window open it stays 75 in there . Ive got one on a timer and one I turn on and off manually because im cheap and don't have a timer. I'm also interested in if its better to step up and down to darkness. Usually the second light goes on 45 minutes after the first one, or whenever I wake up, and the same At night the other way around.
