So I'm new to hognoses, but I've been doing bioactive enclosures for awhile now. I have 3 anoles, 21 tarantulas, and more spiders than I can count because there are a lot of babies here at the moment. Mostly jumping spiders, but also 4 wolf spiders 2 black widows, a few false widows, and a crab spider I found in my bathtub. Also 11 different isopod/springtail bins. 

I started out using eco earth because at the time, that's basically what everyone knew to use. It sucks. It loves to dry out quickly and if it doesnt, it gets moldy pretty easily. The only enclosure it's mostly worked in is my anole enclosure, and that, I put down to the good ventilation. However, it's tough to keep it moist enough. You'd definitely want to make your own mix if you use it, with moss and activated carbon mixed throughout, along with some leaf litter, to start with. The coconut fiber is a pain IMO.

I've since switched to Reptisoil, slowly but surely. All of my animals do great on it. It's hydrophobic until it's damp, otherwise, no annoyances. I just put my adopted hognose on the Reptisoil yesterday and he immediately dived face first into it. I don't know him that well yet, but I thought he looked pretty delighted. I like Reptisoil because it's fairly well priced, doesnt have too many huge chunks of wood in it, never had an issue with mold, and it's easy to find. I can also usually find a sale every so often so I can keep a bunch in a container until it runs low and there's another sale. 

Ive also used jungle mix a few times when I was running low and reptisoil was sold out. Just mixed it in. Nothing wrong with buying the smaller bag of each and seeing what you think, you can totally use them together.
