Another thing you can use for substrate is "orchid bark", available from florists & plant nurseries, & normally it comes in 2 sizes (small chips & larger chunks). As the name implies, it's used by orchid growers, etc. With any substrate like this, you want to really soak & then drain it initially before using, because the warmth in a BP's enclosure will facilitate evaporation & it's hard to keep up just with misting. Whatever options you use, your basic goals for comfort (heat & humidity in correct ranges) are the same. Everyone's set-up is a little different, you just have to tweak things to make yours work.![]()
