I have a divided 75g tank/vivarium to heat. The bottom is glass and 18"x48". I'm buying 2' of 11" flex watt and putting this in the center of the tank. Will likely need to be cut down to 16" to make it 1/3 the length of the tank. But I want to test it at a full 2' length first because the tank is going to be directly under an AC vent (altho the vent not pointed at the tank).

Anyway, I know I'm going to need two misters (one for each side) because maintaining humidity isn't going to be easy.

So here's my questions.

I was originally going to put the single piece of flexwatt in the middle (under the tank) and control it with a single thermostat for both halves, but since the tank will be split in half (with plexiglass) should I split the flexwatt and control them separately?

And knowing the above, what thermostat/humidistat would be the best to handle all of this? (two heaters, two misters)

I've looked at hygrotherm and herpstat 2 & 4. Two hygrotherms would be cheaper than a single herpstat4. But is there some advantage over getting a herpstat4 that's worth the $250 difference? I do want a solution that will last for many years. Are they both as good quality?

How far away from a wooden stand should the tank be to prevent this from becoming a fire hazard? I've read about someone taping styrofoam against the flexwatt underneath. Is that not dangerous??

Aaand finally. Is there something I can put between the tank and wooden stand to fireproof the stand?

Thanks!!
