Going back to Tegus...Need new ideas

[jclaiborne]

Ah I gotcha. I'm actually really interested in the 4x2x2 metal troughs. I think j could fashion a wood/mesh lid. I could then just have the heat lamp/uvb over the screen part?

That could work, however metal will transfer heat faster than plastic. So I guess it depends on how much your ambients fluctuate. The plastic will insulate better so if you were to do a fixture with the bulb inside the tub you could get away with a lower wattage and maintain temps better, metal will act like a heat sink and draw heat away since it wont be filled to the top with substrate.
