I don't have much experience but from what i understand smaller plants don't need THAT MUCh light. if it's just one plant you're raising then a 26W cfl will be fine for the first couple weeks, but i would gradually upgrade to 3 of those. also, try to find CFL bulbs that say "daylight" or "full spectrum" on the box, because those are best for the first weeks of the plants life. of course, if you can find 42W CFL's those are even better, as they give out more LUMENS than a 23 or 26 W CFL. good luck.
