AACT, aerobic activated compost tea. You can go down a rabbit hole trying to build the perfect system. Unless you have a microscope to quantify the beneficial bacteria then use it immediately its just a 24 hr steep of dry ferts, which is good dont get me wrong. But many times the soil microbes either havent multiplied enough, in a less than beneficial ratio, or crash. Many times the brew has no compost in the recipe anyways relying on the guano and manure microbes. Which aren't necessarily soil microbes. The goal is microbes, specifically aerobic soil microbes in the correct ratios.
A compost extract is made fresh. Takes 3-5 minutes to 'make' the ratio of microbes is correct. Good fert nute, humates and microbes to keep soils and plants healthy.
