a couple of cfl's wont work on six plants. you would need 2 or 3 42 watt bulbs for each plant. when you add up the price of all those lights and the cost of electricity, you'd be a lot better off getting an hps light. for six plants, a 400 watt light should be good. just keep them pretty close together under the light. htg supply is the cheapest place i know of to buy an hps light new. they put out a lot of heat though. if you can put your plants and light into a closet and leave the door open with a decent fan blowing air around under the light, you should be ok. definately though, six plants are way too many to bother with cfl's. i only use them on flowering plants that i cant get as close to the hps as i would like. even just using them as supplemental lights, i use one 42 watt light for each plant. also, when someone says that 6500K, is best, they are talking about the light spectrum, not the lumens. you want more blue in the spectrum for vegetative plants, and more reds/yellow for flowering.

The key is to KEEP THEM CLOSE TOGETHER under the HPS light! My biggest mistake was transplanting my plants into massive containers and not bunching them up under my 150w HPS light.
