wich tent to flower in? considering...

Wich tent of a 5*3 and a 3*3 to flower or bloom in?
I would say flower in the biggest expect in this case I want to keep at least three moms and veg at least three plants to ready for a perpetual flower and at somepoint I will want to breed as well and have a smaller space for starts

Whatcha running for a light?

600w hid dimable and about 180 w mixed cfl to start will upgrade

I'd run the 780 watts in the larger tent... if you ran just the 600 in the 3x3, you'd have PLENTY of light, could dial it down to 450 or whatever its next setting down is.

If some of that lighting needs to go for vegging, I run the 600 in the 3x3 to flower, and veg in the other with your cfls, maybe get a t5 fixture too...

Im still learning, but thats what I would do with that equipment. Good luck!
