in my experiences in making teas compost and wormcastings are about the best things to use as your main base. both are full of biologicals and with aeration and the right amount of organic material and food they will flourish
good food and organic material to use is seaweed, mollasses, humates, meals, guanos. you only need about 1-2tablespoons total of food to help feed the biologicals

the teas can be used as a soil feeder, foliar feeder, and some insect/disease control
usually need to brew for about 24-48 hrs
if your brews sit for too long or conditions arnt right the tea could provide a home for pathologenic biologicals.


if you can get ahold of the vermicompost liquid, that stuff is liquid gold
