need input on cfl?? advice please

my clones look like shit i had about 15 of them off the mother i made the mistake by giveing about 13 of them a lil nut n fried all but 2 of them. thes last 3 i had been giveing them sunlight and 2 100w cfls for about 4 days now.. i later found out that giveing them half sun n half cfl is not good... i am going to use cfl lights and i got two 100w cfl bulbs per clone.. how far should i keep them from n how many hrs should i give them light a day ??

I don't see why sunlight would be bad for a plant, ever.

CFLs need to be an inch or two away from the plant to be the most effective. I'd give them 24 hours of light until you're ready to flower them.

I have mine going outside for the daylight hours and back under cfl's at night. I just started doing this a week or so ago due to hot outside temps. so far no problems at all. as a matter of fact they seem to like it alot.
