For
@ChefDGreen and everyone else tuned in to this question/conversation, science got back to me:
Our top-dress formula does contain some ingredients intended strictly as food for microbes, for example, molasses. Some of our ingredients (such as blood meal) are readily available for plant uptake, while others require breakdown by soil bacteria to become available to the plant. Because of this we include a boost of beneficial bacteria:
Bacillus subtilis, Bacillus pumilus, Bacillus amyloliquefaciens, Bacillus licheniformis, Bacillus megaterium. We only include strains that are tested and proven effective, as well as able to survive through packaging to reach your grow.
You are correct in that we do not supply predatory organisms. We also don't include fungi in our formula. We utilize a few species of bacteria known as plant growth-promoting rhizobacteria. As the bacteria grow, they break down the components and secrete acids that contain soluble forms of nitrogen, phosphorus, and other micronutrients for the plant to uptake. While predatory organisms may help balance or further this process, the bacteria are sufficient to provide the plants with the necessary nutrients on their own.
You are welcome to add other bacteria, fungi, nematodes, etc to your grow based on your needs and experience. We often recommend adding a mycorrhizal inoculant such as
@DYNOMYCO to further benefit your grow, though they are not required to keep your plants healthy with our nutrients.
We do not have a product to boost the types of bacteria to add to your Geoflora grow, just the addition of beneficial bacteria already present in our fertilizer. I'm not sure that there is any product available that would provide thousands or tens of thousands of species of microbes reliably. There are also a lot of legal and label restrictions around adding bacterial charges to these types of products, so that's something to keep in mind, too.
