Should i start flowering?

Should i start now or later. they are about 4weeks in veg

its totally up to you and how big your grow area is. I waited until my plants were 10 inches tall then put them into flower and they should get about 38-40 inches when done.

It is completly up to you. All depends on the grower, basically the longer you veg the bigger the yeilds going to be. If I were you I would veg for at least another month then put it on 12/12, at least if you have powerfull enough lights and not just a few cfls. hope that helps.

I would get them alot bigger!! But it is totally up to you. you can do whatever you want. right now it wouldnt be much of a harvest but if you got them bigger it would be much bigger

right now there under a 250w/mh for veg. and i got a 150w/hps and going to add another for flowering.space is 3'x3'x5'
