Kellogg Garden Organics adds bat guano, worm castings, and kelp. Unfortunately they also add non-native mycorrizae, so I heat-treat mine.
Wood Chips
Wood Chips
Any species of wood except: cedar, black locust, walnut, juniper, eucalyptus, or other woods with high volatile organic content. Be sure it's weed-free. Primarily used for plants that require additional drainage.
Biochar, coarse
Biochar, coarse
An incredible substance made when biomass is combusted under high temperature, low oxygen conditions
Biochar, fine
Biochar, fine
The extremely high surface area of biochar means that it retains water and makes nutrients more available to plants. Also used for contaminated soil remediation.
Rice hulls
Rice hulls
If you use rice hulls, make sure they are parboiled! Otherwise you will end up with a lot of rice growing with your plants...
Sand

For any plants that require additional drainage.
Recipe 25: One of our favorites!

1/2 part wool pellets [10%]
Recipe 19: If you need more readily accessible ingredients
1 part Pittmoss Prime [34%] (ask if your local feed store can order it in, through the distributor Concentrates, Inc.)
