good call Invision. Harddon, you can offer a lot to this site but that last comment didn't do shit for anybody except angrify some people. And on a personal note, i very much so prefer the walmart bulbs over "real" CFL. they're cheaper, you can space them out, and they veg better than my 400 watt MH for the first month after potting. I have the warm white (~6500 K) ones too. to each their own though.
