Actively Aerated Compost Tea is a liquid extract produced by brewing high-quality compost or vermicompost in oxygenated water. Unlike passive "manure teas," AACT uses air pumps and diffusers to maintain high oxygen levels, which rapidly multiplies beneficial aerobic microorganisms like bacteria, fungi, and protozoa.
A "proper" AACT 4-2-8 setup typically involves a brewing kit and a specific "Bloom" nutrient pack: aact-4-2-8
: To achieve a high-potassium "bloom" profile, ingredients like comfrey (rich in K), alfalfa, and specialized guanos are added. Benefits for Plants and Soil Actively Aerated Compost Tea is a liquid extract
: High-quality vermicompost (worm castings) serves as the primary microbial source. Benefits for Plants and Soil : High-quality vermicompost
: Microbes in the tea break down nutrients into a form that plants can absorb almost as quickly as synthetic mineral fertilizers.
: Fungal-dominant teas help bind soil aggregates together, improving air and moisture retention.
: Unsulfured blackstrap molasses is the most common additive, providing the simple sugars needed for bacteria to reproduce rapidly.
