I've been reading on this forum alot about racks, and to me for the most part it seems like people just use them for breeding. My friend and I are both BP owners, but are interested in getting a few more. We were looking to getting a small rack system, maybe 4 tubs, with flexxwatt and all that stuff. It seems to me that this is a good and easy way to house the snakes and keep them happy too! Can racks be used for general housing? If so, what is a small one that everyone would recommend? Thanks in advance.
