I am using a mix of CFL and LED. It's almost LED on one side and CFL on the other. Using a 240 watt LED and 12 23 watt CFL. I think they both work well, in my short tent I am beginning to think the LED may be a bit bright. Not much help... But the CFL side, the plants are nice and green and doing as well as the LED.
Ya, options, oh boy, options. There are lots!!One thing not an option is pH control. I have found in my short growing history that it is key to success and critical to the health of your grow. Especially with hydro as you have no soil to buffer with. I am using soil and started my second set of plants (can't count the first I am lucky she is alive!) on 1/4 strength nutrient on day 13. I started using supercharger, at day 3. I am a fanboy for Rock Nutrients and think they are great. You can check out the Q&A in the fert section. Detroit Haze is a member here and is from Rock, he is an invaluable resource.
Keep it up and keep asking questions!! You'll get great info here and it's a heck of a community too.
