What they said, along with compost teas to boost microbial life

Big fan of Gaia Green for myself. Dr earth is also good Down to earth is also good. They are all the same setup. using whole soil amendments as fertilizers, they do contain minerals and rock powers though. The other options are Salt based fertilizers that all ready have the stuff broken down in easy to intake forms. It does not matter how it got there from petro chemicals or organic based things. The end result is all the same, a controlled product with set elements and chemistry. So it boils down to is it a ready to eat salts in liquid or dry crystals, or is it a whole food ingredient that feeds the soil that in-turn feeds the plants. Fast vs Slow With dry amendments you need a good soil microbial life to feed the plants and a PH range of 6.5-6.8 With Liquid you don't need it as much and their are more problems that could arise and a PH range of 5.5-6.2 Both are good options. Just got find what one you think will work best for you and the company that reflects on your personal values. Best of luck.
