I want to add some volume to 1 bag of happy frog soil. I need potting soil, but im unsure of how much more to add. I need some thoughts on what I could add I don't want to compost.
Earth worm castings, bat guano, seabird guano, peat moss, perlite, vermiculite, alfalfa meal, kelp meal, neem meal, karanja meal there's tons of stuff to add. to keep it easy and effective, the EWC, perlite, kelp/alfalfa meal, and guanos will go a long way
