You may consider getting reflectors on those CFLs. It looks like that you're wasting a lot of light by not having a reflector. It'll make a big difference in terms of yield.

Home Depot or most hardware stores will have these clip on work lights with reflectors that would work well in your situation. They are highly efficient with the 23 watt bulb size. Get the wider reflector, not the more narrow one, if you get them.

I hope that you continue this thread with updates; I've always wanted to see how these little Aerogardens do.
