Just my 2 cents...

I'd take off the reflectors/hoods from the CFL's and get the lights to within an inch of the plants. Eh, after repotting them into their own pots. What doesn't unscrew, I'd cut off (after unplugging, of course).

Foil is good to use on things like black electrical cords and unevenly shaped pots. I use it to wrap books to use as booster seats to raise the plants. I wrapped the clothes rod in my grow room and used it to hang CFL's.

Sometimes the best reflective material isn't the easiest to use.

I do have a dissenting opinion about misting, though...I sometimes mist three times a day, right up until the buds begin clumping, since I don't want to create mold. I do this even with CFL's almost touching young plants, as well as with flowering plants under HPS and MH. It's an easy way to offset transpiration that's especially bad in hot, dry weather, or when you are growing in winter and use a dry heat for your home. It's instant humidity, though I don't really use it for any 'cooling' factor. Fans do that...in fact, I use a fairly warm water to avoid any shock.

I know that some plants such as the Japanese Cut Leaf Maple can have it's leaves burned off by misting---or getting garden hose water on the leaves when watering outside. The leaves are sensitive to the magnifying quality of the water droplets.

I use a bottle meant for misting and keep the nozzle set on the finest spray.

But MJ?

I'm a perpetual growing newbie and only know what works for me, but misting is my favorite thing to do to my girls.
