In a nutshell, the house is relatively cool (65-72 degrees) and from what I've seen, the humidity is a little low for many species of tarantula (53% last I checked). Anyways, right now I own a G. Rosea and a C. Cyaneopubescens, both which I've heard are very hardy and fare very well in dry conditions. Because I doubt the conditions are going to change any time soon (well, not the humidity at least) I was wondering which T's do well in dry, cool environments. (Something relatively cheap and common would be nice; I don't want to have to end up paying a bomb)
