So, I have four tanks (glass w/ plexglass lids) housing a normal, a spider, a corn snake, and a hogg island. I'm looking for thermostat to control temps, but I'm wondering what my options are. If I must get the herpstat 4, then I'll have to save. I was wondering if I have any other options, or if people have other ideas? I have done a fair amount of research, so I guess I'm looking for some tips or insight! Thanks!
