Hey guize, I have just come home with my Chilean Rose Tarantula... I was wondering if anyone knows a practical way to heat up her tank? The internet reckons the optimum temperature is between 22 and 30 C, but I can't seem to get it higher than about 19 at the moment... I've blocked out the light and got the heat-mat on the right side of the tank and she's just hugging that side. I am a bit worried.

Any thoughts on other ways to slightly warm it up? Thanks in advance.
