So I am getting my first beardie in about two weeks, he will be about 8 weeks old when I bring him home. I've been doing my research for a while now, and collecting all of his supplies. I want to make sure I have everything for him to thrive, this is what I have so far- 40 gallon terrarium, tile for his substrate, two thermometers, hydrometer, shallow water dish, food dish, 100 watt basking bulb, Reptisun 10.0 UVB, a hide away, hammock, and a piece of driftwood for his basking spot. I've also been temping his terrarium to make sure its ideal, at the highest point of his basking spot it is 115 degrees. the heat around his basking area is about 85-90, and the cool side is about 75. Should I get a heat lamp for the cool side too, to get it up to around 80 at least? I feel like 75 is too cold. Any advise is greatly appreciated!
