Many options all plants have different biochemical components. I mix barley in with my soil for calcium, dont know if it does anything but it was on sale.

Complex organic soil mixes I've decided not to use chemical fertilizers, due to environmental issues, and it just seems better to keep edible and smokable plants organic. So I've been doing some research, and it seems that a mix of perlite, worm castings, and peat or coco coir should provide a good base soil mix. Then there's stuff like volcanite and other natural minerals that can be added, plus small quantities of fertilizers such as bat guano, seabird guano, kelp, and various types of composts. Is there anything else Rating: 5
