You can flower anytime. When growing from seed, your plants are mature when they start showing preflowers.

Good Luck
crabbyback Reviewed by crabbyback on . too small to flower? I'm growing a few plants and I was wondering if they are still too small to start on their flowering cycle? They are all about 12-13 inches tall and the strains I chose do not bush out much. My roomate is kinda freaking out because his daughter is going to be moving in with us for school this year and he would like me to have them done b4 she gets here or at least shortly after. They are about 2 - 2 1/2 months old and have had preflowers on them since they were about 4" tall, even under 24 hrs Rating: 5
