I'm planning on putting some terra cotta decor in some of my PVC enclosures... basically the chia pet stuff, just without the chia seeds. They have some cool stuff that I think would look nice. But, wondering if terra Cotta, with its very porous construction, would be hygienically safe in the long run. Actually, for moisture, I think it would be helpful to wet down occasionally, to help maintain humidity.
Any opinions?
