How long can a turtle go with just UVB, and no heat? The way I have my tank set-up, there is a turtle log under a florescent tube light, and then there is a basking spot that has a T-rex MVB over it.
My smaller RES has not gone up in the basking spot yet, he only basks on the log. Is this ok? Or should i "dry dock" him under the heat everyday for an hour or so? Or should I take the log out, and upset him even more? The basking temp under the MVB is 90 F, and the water is 76-77 F.
Here is the log, and the basking spot, I have since moved the tube light up, so the is is about 8in. away from the log...
