Thanks Guys,
I painted myself into a corner this Feb. by cracking a bunch of UFO bagseeds a friend gave me along with my usual tomato, pepper, squash, herb seeds for my garden & ended up with 75% females & a cramped stairwell to grow them in. Oh ya... and no fancy HID's or any of the basic grow room supplies (+ zero dollars). Couldn't bear to chuck the girls out so I've got 'em crammed in there. Tried some spiral cfl's in round reflectors - PITA, so the Fluorex's have been working out good so far. Did a reverse Spectra-Max design by using grow-lux & warm white T12 bulbs on either side & my pole-vaulting girls have been growing some buds.
Being an unemployed artist, I didn't have much to work with, but I can tell you that these "security lights" beat the pants off lotsa small twist bulbs & all their extra wiring. A lot cheaper too, with replacement bulbs at HD around $15. After I get thru building my diy exhaust/carbon system, I'm going to strap 3 Fluorex's end to end on a 1x4 & use them for the main veg lights in my separate rack system.
