Sorry to DP but the edit time ran out...
This is my current 20L setup right now. Those temps hold consistently and the humidity stays 50-60% at all times because I foiled the top. The lamp has to be in there because its colder in the room during winter but it has a IR bulb and will come out when the weather warms up and I don't need it anymore. Just wanted to make sure I could leave it pretty much as is for a boa. Obviously I will clean it out and disinfect it when I put the current BP resident in her tub.
I do have a few flex branches I pulled out since my BP never used them that I could put back in and I'm not sure if I want to keep the hides since I know boas are arboreal and don't use them so much. From what I've searched I see a ton of differing opinions on this. I know Jimi posted somewhere that he doesn't use them and he obviously knows what he is doing so I'm inclined to go with that opinion. It WOULD offer more space for the fauna...
Again, I really appreciate all the responses and I'm sorry for the noob posts. I just don't want to start off all wrong like I did when I first got my BP and hadn't owned any reptiles before.
