if you have them home made mostly,post them please and your heating solutions.I think alot of ppl want to build them but feel dumb asking about the heat source.It seems very pricy to buy a heat pad for every tub and alot of cords everywhere.Is this heat cable a good way.Ive been looking for a cheap way to build one for a handfull of boas,mainly rosy and sand boas.Is one rope of this stuff good enough to keep them warm.I figure i could buy some wood shelving and some tubs that fit good enough,i dont mind having lids on them,and i guess you could run this stuff under each tub and your done?http://lllreptile.com/store/catalog...and-rocks/-/zoo-med-39-foot-repti-heat-cable/
