Flowering

Working under time restraints, whats the minimum height you would start flowering at to get some what decent yield, there about 13, 14 inches tall right now.

Plenty big right now. Go for it. I flowered at 6-7inches and my plants are at 24 and 20inches. There only on day 17 of 12/12. Still some growing to do.

plants will double in size while flowering, so use that as a guide when to flip the switch to 12/12
