Compost teas can make a terrible ecosystem turn into a thriving one with simple teas. Worm Castings are fantastic to add to you plants, which can help any normal plant look better, You want em greener, then add castings then Chlorine free water and in a day or two, you will have a noticeable difference, this is better done if your medium is very aerated as well.
Vortex Brewers are garbage, the teas made from them are Garbage, this is the wrong process for Organisms to thrive. Organisms and Bacteria need oxygen to survive, a lot of oxygen, that's why you use air stones, and clean them in hot water after every use.
