>>136233Its enough for 1-2 harvests, usually end up replacing the soil once a new harvest starts.
also i feed the plants Boogie Brew compost tea once a month.
Like i said, the key part is the growing medium, the soil. I mix my soil with 2 parts potting mix, 1 part soil, 1 part vermiculite, add 2 cups of Azomite Rockdust, 2 cups perlite, 2 cups bat guano, kelp meal, and worm castings.
