What are some good recipes for compost tea? Is adding fish emulsion good?

There are many recipes available for making AACT. All involve the use of high quality compost. I'll focus on the 5 gallon size, though recipes are available in larger quantities. However, ingredients do not increase in direct proportion to the size of the tank, so please contact me directly if interested in recipes for larger brewers. Recipes are directly related to the amounts of dissolved oxygen in your brewer. As you add more food sources for the microbes, you need to add more air to ensure the tea stays aerobic (above 6 mg/liter dissolved oxygen).

Tim Wilson of Microbe Organics (www.microbeorganics.com) recommends these ratios based on his testing:

2.38% by volume compost or vermicompost (EWC) per gallon = .38 cups or around half a cup max or about 2 cups in 5 gallons max.

0.5 to 0.75% molasses by volume per gallon = 1.28 to 1.92 tablespoons per gallon. 0.75% is the maximum I use. It is a good bacterial and fungal food.

0.063% fish hydrolysate by volume per gallon = 0.16 tablespoon = 0.479 teaspoons or half a teaspoon

0.25% (max) kelpmeal by volume per gallon = 0.64 tablespoon or half a tablespoon
