you wanna put them under the cfl's as soon as they sprout, but before that, no light at all. keep a fan blowing on the cfls so you can keep them close to your plant. they sell a 43w cool watt at HD and wal-mart i think, 2 or 3 of them would be alright for the first two or 3 weeks and u dont need any special socket to use them. keep us updated man looking forward to see what will happen with your grow.

peace.-n-smokeallday
