so I searched around before posting, my question isnt really 'what should I get', its more of a how do you guys have your tanks set up. I know most people have racks, and I've looked into going that route myself (display cages, not tub/breeder type racks). I know tstats regulate temps, shut down power when its at the temp you want and stuff, but I was trying to figure out if all these products only came with 1 probe. I was looking at the Johnson Controls Thermostat but I have a few tanks in the room, which is all I have in that bedroom so figured a space heater would be easier. I have UTH on all my tanks (exo's I think), so I'd have to get a separate probe for each tank... do any of these have an option or come with more than 1 probe, and if not what would be the best way to regulate the heat in multiple tanks.
