PERFECT for the bottom of your fruitting chamber. Your cakes will sit right on top of this after you've sprayed a bit of clean water on it. Don't overdo it! You can always spray it with more water as it dries out, just don't spray your cakes down on accident. I swear by the out-grow brand of perlite. Very very good quality.
