I find it rather unbelievable that ANYONE can build a compost tea brewer for 500 gallons of tea for under $100. Something smells very fishy. And if you know about making AACT, if it smells fishy, could be something seriously wrong. And I also want to see the lab results from you tea, especially your ability to have good fungal count in your tea or protozoa! How long do you brew? What do you add to your brew? Do you do any activation to your brewing material? Lots of questions...few answers!
