Ok, so I have a 2 year old male BP, I've been keeping him in a glass tank since I've had him but have grown tired of trying to keep the humidity up to par. I'm planning on moving him to a sterlite bin so I have some questions .

I've read the uth's I have aren't real efficient on plastic bins so I want to move to heat tape and a new therm. Right now I have the reptitherm 500r that I don't want to use because it's a pain. Here are my questions.

1. How much flex watt should I get? The bin is approximately 33 long and 19 wide.
2. Is flex watt suitable as an only heatsource?
3. Thermostat, since I only have the one BP will the hydrofarm be suitable?

Also, my girlfriend ordered me a new baby butter bee so I'd like to get his bin set up as well before he arrives (too dam cold in wyoming have to wait for better Temps )

Thanks for reading.
