Well, if a PVC is best to begin with, I'll start with that. A smaller PVC, but one nonetheless. Maybe if need be, I can even put a smaller tub into it or scrape something over the front if my snake is still too uncomfortable with it.
The Sonorans wont be born until the Summer. So, assuming they're born at the end of May, he'd only be about... 4 months old? Unfortunately, boas are... difficult to find in my area. I'd really like to meet my snake before I purchase it as well(plus supporting a local business), but if I need to have one shipped, that's okay.
For Sonorans then though- are they okay on coco fiber, or do they need sand like in their natural environment? Do they like a lot of substrate, or not care at all? What do people do to keep their humidity up? Will a 40watt RHP be too much for a 2x1.5x1? I'm thinking of asking for a custom that's a bit taller, but I'll have to see how much it costs. It might just be easier to buy a different premade PVC that's a size up if custom making it is more expensive.
I'm currently looking at getting the acurite for thermometer/hydrometer, but I've heard that simple analogue hygrometers are the best ones? I also found something called a hydrostatic 2 I think, normally used with cigar boxes, that was recommended. For a temp gun I haven't looked yet but I am planning to get one, and I've been looking at the herpstat 1/herpstat EZ for a thermostat. However, I'm not sure how many heat sources I'll have- heat tape+RHP? Just the best tape?- so I'm thinking I'll need the EZ2/herpstat 2. Is there a big difference between the EZ and the standard?
What size hides are needed for a few months old snake as well? I'm not too great with spatial awareness, unfortunately.
