Lowes and Home Depot have 42 watt Spiral CFLs for $10.98 each, plus the socket and reflectors are $7 to $11 each, depending on size. That is the smallest wattage to consider. You need an equal amount of RED and Blue Spectrums, or the Bright Whites and Cool soft whites mixed to give a full spectrum. Blue Spectrum, high Kelvins (BRIGHT WHITE, 5500 to 7000 range) are for VEGGING. The low Kelvins, sift white (cream colored bulbs) are for FLOWERING.
