I read they will double in size of what they are when you change to 12/12 by the end of flowering and may grow larger if Sativa
ProjectEight Reviewed by ProjectEight on . Changing to 12/12 My plants are at about 15", My question is when changing to 12/12 will my plants double in size? When changing to 12/12 should I drop the times slowly to get to the 12/12 cycle or should I go straight from 18/6 to 12/12? Rating: 5
