also, im thinking of buying New Wave High Output Fluorescent Plant Grow Light Fixtures by Sunlight Supply at Home Harvest Garden Supply a 4 foot ballast/fixture with 2 bulbs, but im not sure which bulbs i should use. The 3500K (daylight) ones, for a total of 10,000 lumens, or the 6500k (cool) ones for the same lumen count, or should i mix it up? I mean i just want to make one purchase, and I already have a decent number of cool lights from the cfls, Do you think i need more light? keep in mind i have atleast 3 more cfl's im waiting to add on. I also added a 200w incandecent bulb, just because i had a lamp with a 200w bulb laying around, might as well use it.
