I have 4 4ft flourescents going in vedge room.
Its a hydro sys with grow micro bloom from advanced NUts.
In the flowering room its 4oowt hps, I try to alternate 400wt mtl halide for first weeks blooming to increase growth. then the rest is done with a single 400wt hps
my bloom room is 5ft wide x 9ft high x 6ft long. blooming grow tray is 4x2ft 8-9 inches deep
basically 2 cycles of veg, 4 cycles of flower. clones are rooting, while another set of clones is two weeks vegged, another set 4 weeks veg, another set 2 weeks into flower, another set 4 weeks into flower, 6wks flower, 8 wks flower..... make sense??....
