can people please post recorded tortoise temps taken while basking and then the ground temps under same light.it is my understanding that a tortoise sitting under a heat source being of greater mass than the surounding air and substrate can absorb and hold more heat.this is why a rock under the light can get hotter than the substrate.so if you take a reading of the substrate and it is 95 degree's,what is the temp of the tortoise and how long did it take him too reach that temp?if he needed too bask longer too achieve an optimal temp would he not benefit from the longer exposure too the uv?or is this exsposure detrimental?
