You could, however you will see reduced yield, autoflowers do best with 18-20 hours of light a day. Happy growing.

Lighting, to early, flowering, can I stop this or no. New grower
Might be dumb but eh ohwell 1st time grower. Need to know for my next seeds I plant.. So I messed up by putting my plants to early on the 12/12 schedule, now they are starting to flower. Super short! No way I can stop it right? To get more out of my plants?

Should I Scrog? Confused!
My garden seems healthy despite me. Guys I'm confused as to what I should do. Plans are to ScrOG at 18" (which I have never done) with a screen that is 3' x 4'. This screen would cover the entire container area plus about 4" over around the edges. Should ScrOG or just let grow?

Sexing Seeds
What is the best way to identify seed sex? Flower and switch back to veg or take a cutting from each and flower those? I ultimately want to end up with a Mother from the seeds.

Putting back into veg before pistils and sexual maturity?
Can you veg even after a 12/12 from seed has been in flower room 3 weeks shes just not big enough and would also like to top her so I really am considering it, the reason being is I can't see one pistil yet which means she's not mature, I don't see why it would make a difference

Auto wouldn’t flower until 12/12, switch back?
So I have this cream mandarine auto that would not flower. I had it at 12/12 for he last two weeks and it finally started. Should I just keep it at 12/12 until harvest or can I switch it back to 18/6 to speed it up? Will it re veg? Relative noob...

Oops- might have messed up and have wrong lighting???
I might have confused the two strains I’m growing and have been treating a photo period as if it was an auto (18/6). In week 5 lots of preflower but no real top buds formed yet, I’m wondering if I screwed up with too much light. Should I switch to 12/12? Will 18/6 hurt a photo

Weird Autos (RQS NLA, same strain) still vegging day 50. Only some preflower, but nice plants. WHAT would YOU do?!
This is the most unpredictable auto flowers I've ever had. It will be 50 days soon and only preflower on one plant. Ive used a 12/12 light schedule on autos before. Should I try this on these plants? If, so keep it 12/12 untill the end? No turning back to 20/4 when they go?
