Question regarding our Greek. We live in the central valley of california. I built Tommie a pen in our yard that is approx. 6' x 4' with three small bushes and a small rosemary plant. On the suggestion of the guy at the pet store (who said he has had sulcatas all of his life) I set Tommie up with a 100w Exo Tera Infrared heat lamp. Right now it is positioned above a makeshift hut made from a few 2x4's and some plywood. The roof is open only enough for the heat lamp to shine through but the rest is covered by a folded towel. The guy said the tortoises can't see the red light so it won't mess with their sleep cycle. A guy at our Zoo said that's bologna and that a heat pad is what we need. Any thoughts or improvements on our setup?
