im growing with CFLs, you need A LOT of them. reflectors + mylar/flat white paint on walls helps.
MH is the shit. i did that last time before i moved and couldnt bring them along =(
Now the cfl jihadists are going to be on your back. I know this isn't PC but all light bulbs aren't created equal. Some are just naturaly brighter than others!people get sooo touchy when you diss on CFL bulbs. But in all honesty, they suck ass for growing purposes. Even supplemental lighting..you get soo little bang for the buck.
