Soooo.... For your problem I would say turn on the lights, 16 hours a day, which will help with heat, and start using the peroxide/water mix, 10:1. I'm not strictly accurate... 1 quart, 32 oz, 3 oz peroxide. One gallon, 128 oz, 12 oz peroxide. But I always measure, be careful, stronger mixes are use as a weed killer!

And use cinnamon. I keep it in a salt shaker near the trays, and sprinkle it on whenever I smell something a little musty or if even a single gnat shows up. It doesn't bother the babies at all.

Good luck!
