Sunlight + CFL's?

Hey guys.. Got another quick question that I am hoping one of you pro's can answer.

I Have 3 girls that I have been growing in 5 gal buckets in my backyard since clone. I got a late start on them, and have been messing around with their sun time.. Only allowing them to get 12 hours of light everyday, in hopes they will finish before the end of OCT.. Anyways, its going good so far, been getting up at 7am every morning to take them out, and putting them where I know they will get the sun as soon as it hits my yard.. but this isnt until around 10:30 am. Then its sun right till 7 pm.

I am wondering if it would harm the plants at all, to leave them in my shed from 7 am till 10:30 am under a few 2700K Lumen cfl's, until I can get the sun in my yard. I know they are probably getting more than enough sun every day as it is.. But there can never be too much right? So I guess my question is.. Can you mix up the type of light a plant gets (Sun + CFL) without stressing it?

I think you should stick to what you're doing and not do any cfl mess.

indirect sunlight is a lot more powerful than some cfls

Aloha Bigboy I agree with poplars as far as the indirect sunlight goes. And yes you can mix up the type of light. I take my clones outside during the day and in at night they get 24/7 light. Once you have a good strain of plant it will not herme on you when you do this. I get my plants about 3feet then take them out. But I also live in the tropics.
