So, I bought some Eco-Earth yesterday for my gecko and I have a lot left over. I was planning on using some for my BPs until I run out, because the Aspen is still sealed anyway. It's been soaked in water (the brick) and expanded, but how do I store it? Last time, I left it out and moths got into it. But I am also worried that, if I store it in a tub, that it will develop mold.
