Substrate Question(s)

[HeatherRose]

Hey guys...

This might sound completely stupid (or not, not quite sure), but I have some questions about substrates...

I mentioned in another thread that one of my Brazilians always messes up her paper towels and appears to enjoy burrowing in it.

Now, I've always been a paper towel/newspaper girl, so I haven't really given snake substrates much thought - ever. I'm a complete newbie to snake substrates.

I've gone off and read several BRB caresheets to get an idea of substrate, and I've seen potting soil, mulch, moss, and shredded paper as recommended options. I'd given carefresh some thought, but it's kind of ugly and gets compacted down under the weight of the snake (I used it for my ball python temporarily) and makes burrowing harder. If it comes to having to, I will use it.

I know that not all caresheets are up to snuff so I wanted to ask those of you with experience. What does everyone think about potting soil (this just doesn't sound right, but I'm asking anyway), or ecoearth (I'd prefer to use this above everything else)?

Thanks in advance.
