Young Autos on 12/12. Will they fower?

Autos flower when ever they like. U can put it in the dark for 3 days then go 12/12 and it still wont flower until its ready. Keep lights on 18/6 for Autos the whole way thru for best results.

Yes it will flower. As an autoflower it has a set genetic schedule that will flower regardless of light schedule.

It should flower, just dont expect great results chop harvest time. If you have no other choice then you are gonna have to do it, if you can avoid it and can instead give it 18/6 or 20/4 then do that ;)

Since it’s an auto it will flower no matter the light schedule. Everyone runs autos different, I personally always do 20 on 4 off with autos. But again that’s my preference. I would recommend more than 12 hours of light , at least 16. But again that’s just my personal recommendation, good luck! Happy growing!

It’s an auto flower. Let it decide what it will do. Keep it at 18-6. No point in 12-12. Keep a longer day for fatter buds.
