well since I use t8's with rhp I like to use straight aspen since I don't need to extra humidity plus my bp will not borrow in anything but aspen (go figure lmao). now if iv got a temporary setup in a glass tank(quarantine) I like to use reptibark it generally give me the humidity I need until they blue then I just lay a damp rag over the top of the screen and that gets me to 70-75% humidity so I don't have to mist multiple times a day and get those rapid humidity fluxes . I only have one bp at the moment but I just bought two bci boa's so right now I have two glass cages for quarantine set up like this and im in the trial and error phase getting everything setup and ready to go before they get to me (next week due to cyber week) so take my info with a grain of salt lol
