My Eco Earth just arrived and I have heard people mention mixing it with organic fertilizer. This seems like a good idea to me and I was wondering what kind of fertilizer to use? Is it the same as organic topsoil? I dont really know anything about fertilizer or topsoil but i would very much like to experiment with that mixture. It seems like it would be great for digging and holding in moisture. Would this mixture attract bugs, mites? Would it get moldy or start growing things if I kept it moist for humidity? Please comment and let me know your experience and the pros and cons of this mixture. Thank you.
