That depends on if you want to start flowering or if you want a vegetate for a while if you're going to start flowering then a 12-hour days is what you want right. But if you're going to vegetate for a while then you got to extend that day to at least 14 hours so if you're going to bring them in are you going to put a light over top of them for a couple of hours that's probably all it would take 2-3 hoursYep. I got same one bro, thanks. I guess im just gonna put the girls to bed at twilight times right?View attachment 1044296
