Just in regards to tanks. I live in a cold environment and run a 150 watt Che in a 40gal long tank. I added insulation to the screen top and it changed my world. I mist maybe once every two days and have a humid hide and my temps stay good. Might help for the time being till you get your tub set up. There is a diy tub setup on here that has a Che and light setup.
