I grew 12 plants with 1 150 watt red cfl,2 100 watt blues,and 1 regular white cfl, in clear cups with half peat moss and half miracle grow slow relaese(ran out of reg soil) . I did however use a organic fish emulsion fertilizer(which u can find @ walmart n local stores)and those basterds looked like little cabbages, dense thick green foliage, so ur doin pretty good
