Compost tea as a hydroponic nutrient
I don't know if "traditional" compost tea can be used in hydroponics. The tea boosts a variety of micro organisms which are beneficial to soil-based cultures, but there are numerous warnings that it can also introduce disease this way.
I'm not interested in micro organisms and I also doubt whether they are of direct benefit to the plant. I think the tea contains organic substances which stimulate growth and immune responses in the plant.
However, I can't find an authoritive article on the subject. Every one sings the tea's praises, but . . . what exactly for?
Does anyone have an opinion on this ?
