Just my 2 cents...
In retrospect I’d start all my snakes in tubs or avdivided adult sized enclosure. I’m upgrading some enclosures now and it’s a pain. A 4x2 is plenty of room for most BPs but bigger is cool too. I’m not a fan of wooden enclosures and would suggest pvc enclosures instead. You eliminate those pesky heating and humidity issues. When it comes to humidity, which isn’t as important as we sometimes think, the right substrate can make a big difference. I’ve been using Reptichip for the past few months and I really like it. As long as your snake has fresh water, and is properly hydrated, then they’ll be fine with ambient humidity.
Best wishes with your new critter. As a former BP keeper I would pass on the Royal and get a boa.![]()
