FIM them now, wait about 2 weeks and flower. You should really wait about 4 weeks after FIMing to flower, but it wont hurt that bad to do it in 2. After 12 inches a plant, grown from seed, is mature enough to flower. They will get about 36 inches tall when done depending on the strain if you flower around 12 inches tall. If you FIM you will more than likely get a larger harvest. Are you using flos? or HIDs? laterz..
Megatron Reviewed by Megatron on . When to FIM? Flower? Hello all. My plants are almost 7 weeks into the vegetative phase and are roughly a foot or so tall. I was wondering if it is too late to try to FIM the plant and secondly how much longer should I leave them in veg before beginning flowering? Ignore the droopy leaves, the cabinet was hot as one fan burnt out, it has been replaced and they are happy again. Thanks for the help. Rating: 5
