So i have a tank 29 gal. I had to get it since it has a stand. Filled it with sand and calci sand mix.... gonna get an adult ... have place for him to hide and rock for him to rub against...everything....however main problem is i bought these temp and humidity gauges ...but even for their price they seem cheap. And i bought a porcelain exo terra glow light lamp so it has light at night as well. So far Ive had the cage on for a few hours and it seems that the temperature hasnt risen inside the cage its staying at 75 and i live in a central air house so i cant make my room warmer. I just dont understand why the lamp isnt working and heating the cage. the light is hot but the cage isnt getting hot. I would get a a UTH but the cages stand has no top. The tank sits on the edges so I would have no place to put it. Is there any way i can keep the tank warm.. I would cover the top to keep heat in but that would make it loose ventalation..please help
