I recently made a batch of CMC compost containing 5% of 2 types of locally mined high Si clay, in 400 gallon smart pots, shovelling back and forth between 2 of the 400 gallon smart pots every day or two for 3 weeks then a month or so to rest.. was made with 3 bales peat, 3 bags organic alfalfa pellets, micronized soft rock phosphate (from idaho), humalite superfine powder, high-Ca lime, gypsum, trace sulfate based minerals and hydrated with 50 gallons water + a gallon or so AEM and a 1/2 lb biozome, plus some biodynamic preps.. I mix it 1 part compost to 6 parts pro-mix hp on the average plant, more or less depending on their needs..
so far so good, I am curious how much compost tea do I really need to add to a soilless mix that has it's fertility based on compost? do I really need to keep adding CT or is adding microbial foods to the plants just the same since the root zone is aerobic and fully alive? out of curiousity I put 1 cup of the compost-pro-mix hp blend in a cup of distilled water and measured the ppm and it was around 4x higher compared to the uncomposted ingredients in the same test
