So, I'm planning on brining home my new bp this week. I can use paper towels or blank newspaper as a substrate, but I'd rather use something more natural looking. The problem is that I'm highly allergic to aspen and most other plant matter. My question is this: Does anyone ever use organic, pesticide and chemical free potting soil? What would be the pitfalls for this. What are my other options if most plant matter is out of the question?
