“An aerobically brewed Compost Tea requires a microbial food source in order to significantly increase the numbers of microorganisms beyond the concentration that is in the initial solution of compost and water. Growing Solutions Compost Tea Catalyst was developed as a balanced nutrient source that supplies complex carbon and other nutrients to enrich the growth of the natural biodiversity of microorganisms found in the starting compost material.”
Vicki Bess, BBC Laboratories, Inc., Tempe, AZ
Biodiversity is the key to resilience in natural systems. Good compost contains a broad diversity—thousands of different species—of beneficial microorganisms, many of which can be extracted into solution. Adding a supplemental food source during the Compost Tea production cycle promotes robust growth and proliferation of specific types of desirable microorganisms. Growing Solutions Compost Tea Catalyst is a microbial food source that contains soluble kelp, rock powder and a blend of botanical ingredients formulated for optimal microbial growth and diversity. Compost Tea Catalyst contains only complex carbohydrates—no molasses or simple sugars.
