    Daylight are the best ones to use, because they have the broadest usable spectrum.
    Some folks will say warm white are better for flowering, and in one way they are right. The plants prefer more red spectrum when flowering. But if you use ONLY CFL's, watt for watt, the daylight bulbs will give your plants more usable light.
    All other factors being equal, more lux on the plant will give you better growth than more red spectrum from less lumens. Understand?
    If you have two 25 watt bulbs, one warm and one daylight, the daylight bulb will give more light from the part of the spectrum the plant can use for growth, even though it would prefer more red in the spectrum.

    You forgot to mention the wattages, so I'm assuming they're about 25 watts each, in which case you have enough lights for significant budding. More will definitely improve your yield, but that's your call.

    Here's a link to some T5s for ya: High Tech Garden Supply

    avg temp im not sure but the space is maybe about 3 feet wide, by about 4-5 feet deep and i can walk in it. the lights are relatively close to the tops and sides, and they have reflectors

    i am trying a grow with 2-200 watt compact fluro's 36000 total lumens for 4 sq. ft. will post pics soon. i saw a website from uk that has hoods for sale that take 4 and 6 large cfls 125-300 watt ones, the 6 bulb one is approx a sq meter. they have 150 watt bulbs rated at 18,000 lumens also(mine 18000 l for 200 watts). so that 6 bulb hood would be 900 watts and produce 108,000 lumens(approx 12000 lumens per sq here), heat would no longer be an issue in this grow. what you guys think?
