Can you put a clone into 12/12 right after it roots? Cause i read that this 1 dude cut 2 clones and put them right into 12/12 and ended up with like a bud on a stick that grew, had pictures.... kinda wanna grow a little 1 for the hell of it. i don't have much room in my grow room, so a little 1 would be perfect.you can grow any MJ plant on 12/12 from seed.
IMO it is best to use blue spectrum lighting for around 2weeks at the start. During the first 2-4 weeks the plant will continue to veg , then the plant should begin to get alternating nodes and pistils. Then budding will begin.
With the right environment/care you can easily pull +15g when going 12/12 from seed. Generally with around a 15inches tall plant come harvest time .
