Tap water in a 20 gal container with air rocks inside. We got fresh air coming in through another room of the house and a exhaust stright out of our chemney. What temp should we be looking for and is 75 a bad thing?

Buy a small T5 flourescent, 1000 watts is way to much for plants that size. Little plants don't need anywhere near that much light you are just wasting energy and your running 24hrs. At the very least cut back to 18/6 with the light.

Other than wasting money are the lights actually hurting the plants?

Yer lights are fine, he's right about cutting back to 18/6. No, ya arent hurtin the plants w/that, but ya are waistin electricity.
Didnt realize ya were hydro, cant take the time fer imageshack to load.
Mine are almost all goin thru a yellow tip phase, but I know they'll be fine.
And 75 is IDEAL temps, I'm just shocked ya have the temp that low w/that 1KW that close! You are taking the temp from @ the plant canopy, right?
