eh if u got a home depot near you or lowes go there any general lighting store/hardware store carrys CFL's spiral are cooler i believe CFL's when used right = good grow decent yield etc
use CFL's for veg and maybe to flower keep the light no more then 2 1/2 inches away from the top of the plant no more strechting i hear LED light sucks for bud
i have t-8 daylight simulation lights 32watt each im going to attempt to flower with them. Money is tight dont think i can afford a HPS at the moment :( or t-5's
i think its a differnt strain maybe sativa dunno they are taller then the more mature plants still bag seed
i am thinking about getting some auto seeds less work ;) either lowryder #2 or auto kush/ak47
move the light closer bro you want your plants to have close nodes HPS should be 1-2 feet away floresent lights should be no higher then 1 to 3 inches away from the top of the plant
Good Luck
