I was wanted to find out if there is an particular brands or types or alternatives to the petstore bought brick coconut bedding?

I have been doing research and came up with organic potting soils but no brands? I want something I can purchase from an big chain such as Lowes, Home Depot, Menards. I did see some mention Miracle-Gro Organic Choice Garden Soil - Scotts Miracle-Gro "Miracle-Gro® Organic Choice® Garden Soil" I can get a 40lb bag for only 4 bucks which is hella cheap. I know they may not hold moisture as well but all my tanks use a fogger/humidifier.

So what I'm trying to find is a cheap alternative to the petstore substrates.
