I've done it and yeah man it works. Right now tho, I use CFL only at the seedling stage and swap to a 150 HPS after a few nodes. Add LED later on in flowering. But I only grow 1 or 2 plants. You might also consider COB led. I have a hankering to try it myself but all in all what I got works great. Keep in mind CFL is almost as hot as HID. And u can get a 150 HPS for $65 shipped on eBay. A dimmable 400 for under $150. I'm not sure about the COB. Seems most build there own. Lots of choices. To be honest, CFL is at the bottom of my list but I know it works.
