i've had my critical jack on 12/12 basically from seed. I let it veg for maybe a week. I'd like to know a couple of things: 1) How long does it take mj to flower when grown 12/12 from seed? 2) How long does it usually take for mj to flower after switching to 12/12?
You did just ask the same question twice and you have 384 post's...? Please tell me this is a joke!? I would like to know a couple things also... 1- Do you think you're funny? 2- Are you a funny guy?
Marijuana can take anywhere from like...6-20+ weeks to completely flower, so this question isn't possible to answer. Most the varieties will flower from like 8-10 weeks, plus add the 1-2 weeks to induce flowering after bringing in 12/12 lighting. It really depends, you won't get the right answer on here.... but you will get answers.
Thanks for your answer. I wasn't wondering about "completely" flowering, though, just how long it takes before they begin to flower considering the two circumstances (if different).
20-45 days till sprout is sexually mature( will not flower B4 this), after that it is up to strains genetics.
