Like title says I screwed up photo plants grew big fast my autos 2ft tall around if I switch to 12-12 will it really screw me up? 3x3x6 grow tent 600 watt hps 600 viperspectra real watt 275 I was hoping that much light I won't hurt to badly can't you also do 13-11?!
 
Are you trying to flower photos at the same time? If so, you need to go 12/12 or something similar. If it's all auto, no need to shorten the day. It will cost you a little weight on the autos.
 
You can finish your autos on 12/12. It isn't ideal but you'll be fine. Contrary to popular belief, your autos will not just up and drop dead like they are on a life span timer. They will just chug away @ 12/12 until they are done.

I don’t recall the yield being off really. Years ago in college i used autos because they were fast and short. I’d run em next to my photos and switch to 12/12 after a month, harvest the autos when they were done and let the photos finish off for a semi perpetual harvest lol.

When pressed for space it worked.

Couple oz per plant under a 400w sounds about right.
 
Thanks for answers I'll let you guys know what happens I'm switching to 12-12 now n a couple of oz under your 400 watt? I would be more then happy with that yea they got about a month under 20-4 n one of them is 3ft for a auto lol things r getting good now :)
 
I meant to say yes you can. It dies hurt yield. It just depends on when you go 12/12. I grew some from seed at 12/12 and only got a few joints worth. Same seeds under 20/4 the whole time got 3 feet tall.

If the stretch is done on it then it won't hurt yield as much.
