Dr. Azomite would be proud of the process you used from beginning to end! I will keep a copy of what you posted here and look forward to updates. Just curious, what size pots are you using?
Glad that you mentioned "With food going through the roof in a number of months....," friends of mine think I'm crying wolf about future food prices, but I tell them energy is a big component in food prices and then ask how much are you paying at the pump? I saw a couple today and told them to load up on food now like I warned the wife in January 2020. They got into their car and went food shopping.
Look forward to you updates and good luck!
