yeah, in that case I would definitely recommend release (or that they let you keep them). I use a 40 breeder tank for my babies so I can get a proper heat gradient set up, then I use a thermostat hooked up to a dome fixture with a ceramic heat bulb at one end set to 81 or so. That is the hot side. The whole thing has a flourescent UVB bulb (I use reptisun 5.0 or iguanalite 5.0). Substrate is usually 3-4 inches of bed-a-beast mixxed with soil. I scatter some grass or clover seeds around on top, plant a houseplant or small fern, make a rock cave, put in a glazed ceramic plant saucer (really shallow), and that's it.
The light is on a timer, the heat element is on 24/7 with the thermostat. Keeps it warm at night.
With this setup, I feed daily by removing them and soaking them for 20 minutes in a few mm of lukewarm water. Then I feed them in a nother bin for 20 minutes (no water in this bin). While they soak and eat I clean their water dish (EVERY DAY! this is a must!), check the plants in their tank, water where needed, and mist the whole thing. THen I return them home and sometimes put a butterdish lid in there with a few fruits/veggies on it to snack on.
I move the feedings to every other day after about 4 months. At 9-10 months they move outdoors permanently.
Works great for me now that I've figured all this out, but it's kind of a lot of work each day (about an hour every evening you feed), and if you don't have the supplies, a thermostat, heater element, uvb bulb, uvb fixture, dome fixture, tank, and the misc extras can add up fast.
