I use 240 watts of sidelighting CFLs with my 400, and my average yield is 10-12 ounces of buds, plus 2-4 ounces of leaf (including good trim leaf), with two or three plants. I have never hit the 1 gram/watt/grow point, and probably never will, but I do keep trying!
jamstigator Reviewed by jamstigator on . well winters here and i want to grow still so im thinking about growing in the space under my staircase. i've got a spare clamp lamp that i use for my lizards. Now i've heard about "cfl" and hps" lighting... but i have no idea what this stuff is. could anybody give me some info on what kind of a bulb i need to buy for a standard grow, and where i could buy it? i hope this is a reasonable question to be asking thanks:) Rating: 5
