blackout bags to stimulate 12/12

Hey fellow stoners, got a quick question.

I have 25 plants spread out through...150 acres, and was wondering if i could use blackout bags (close to body bags) for stimulating 12/12.

My plants are mini-beasts right now, they've got their 5s, but im waiting another 30 days from april first to stimulate flowering. Theyre probably big enough to flower right now, but id rather wait another month to see them get bigger, and to see if they get their 7s.

ive always wondered about using blackout bags to stimulate 12/12, just never tried. and didnt feel like asking around. so if anyone knows if it works or not lemme know. ill fedex you some pot if it works. lol

Oh yea it sure does work. I've grown indoors but what I did was follow this thing here :

which is just like your method. What you have to do is though to make a good seal so that no light gets in that area and bob's your uncle you're good to go.
Good luck!
