Just curious. I was searching coir in bulk and found organic compressed coir on both vermiculture and hydroponics sites. The price was considerably less than the Eco-Earth.
If you can share a link this would be helpful. Hard to know without reading ingredients, description, etc. You want a pure compressed coconut coir. Anything sold for pets is marked up in price so likely if this substrate has other uses you can find it cheaper. Just want to know what you're buying, and that's it's safe/clean for pets.
