Have to keep the veg and flower seperate. 18+ hrs for veg and 12/12 for flower and the light height has to be even or the plants will reach and stretch for the light.

Thanks for the info I've been lurking for quite a while now just reading everything I can. I already plan on vegging under a 400w MH in a seperate area. I suppose I could move the new plants higher to equal the height of the old plants.
