| | Re: How-To: Mineralized Soil Substrate, by Aaron Talbot
Is it possible to use Potassium Carbonate(K2CO3) instead of the Potassium Chloride(Muriate of Potash)? Continental Clay Company here in Minnesota sells everything needed for this except the Topsoil.
Edit: Found a place called Brew & Grow in Spring Lake Park, MN that sells Muriate of Potash. I am spending about $15 for the MTS mixture and I already have 3M ColorQuartz for the inert substrate. I love the internet for it's searching power!
