I let mine range from 18"-24". Keeps them manageable in the area I've got (height) and their not crowded so there's plenty of light to go around.

Have a good one!:thumbsup:
Psycho4Bud Reviewed by Psycho4Bud on . Vegg state theory. Hey.quick question....how long do you guys usually let your plants vegg for? I know it's totally up to the grower to decide when they want to start flowering, but i just want to get a feel from some experienced people out there. In theory....i i were to start flowering after my babies were only 2 inches high...would they still flower? maybe enough to get a joint or something? I"m not doing that...but its just theoretical..
