During, germ and veg. instead of using one type of spectrum of cfl lighting would it be more beneficial for the plant and make it stronger if i gathered a variety (Daylight, Cool, and Warm, Spectrum) of bulbs taht are placed on a horizontal piece of wood abouev the plants. about 4-6 lights?

Ive been kinda curious about this but from all i can gather about CFL's you use the 6500k ones during seedling and vegetative cycle and then you want to use the 2700k ones. What im not shure is if you take the 6500k ones out when you enter the flowering stage or just leave them in there with the others.

If you can leave them in there AND use the 2700k ones, well sure, that'll help. If you're asking whether you should buy three 2700k's and three 6500k's, and you want to use six lights for flowering, then no, get six 2700k's. But if you already have some 6500k's laying around that won't be used otherwise, and you can keep your temps under control, throw them in there too!

I don't know that you can really go too overboard in terms of lighting with CFLs for flowering; the more the better. I just packed 500+ watts (real watts) of CFLs in a tiny closet (2 big bulbs, 12 smaller bulbs), and I'm trying to figure out if I can get more in there without tripping a breaker. I'm not even bothering to worry about the spectrum either - I'm just putting every bulb I have laying around in there. I'm hoping I can squeeze another eight bulbs in there, bring it up to 700 watts. Lol, pretty crazy, I know.

hey, my flower box consists of 4 48'' flo tubes 40w 3400 lum 3000k, and 16 23w 1600lum 2700k cfl's! the more the merrier!

Do you mean 700 cfl watts or like each 26 w cfl puts out 100 watts? So you have seven of those?
