I would think that your better yields would be with the HPS all the way. Use your CFLs for the seedlings. Or run all bulbs all the time... ???

What CFLs do you have?

::::::
Mylar vs white paint.

Yes, use Mylar if possible. There's a very good explanation in the FAQ section.

Correct pH water will give you better results... IMO.

As to the fans::: You've got to do some testing man... test, experiment, and test some more.

Try out different setups... until you find out what works.
