I've got my new soil mix almost done but one of the only things I'm stalling on is the use of these diatomaceous earth pellets I bought at an auto parts store. The bag says 100% dte and also suggests use in kitty litter. I know I've seen it mentioned several times as an aeration ammendment here and i thought it would be a good addition because if its silica/mineral content and insect control properties. I've rinsed it well and only plan to use it as 2 of 11 parts of my aeration. I just need confirmation that it's ok to use before I ruin over 20cf of soil with it.
