total 208W / 12800L in my 2' x 3' grow space in the closet. These lights are about 1" above the plant tops. At bud time I add 2 ea. 42W CFT 2700K 2660L for a total of 290W / 18120L.

These are all screw in "twisters" avail from Home Depot, Lowe's. Save-On, etc.
that's because the wattages posted are all wrong. where it says 150wat i'm sure it means 42watts, you see what i mean. what's your yeild with all those cfls? i had a 354watt cfl grow that yeilded about 4 1/2 oz continually. just curious what others are yeilding with cfl grows, i could only get 1/3 gram/watt or a bit more with them and i have no prob getting 1gm/watt with the hps bulbs.
