VermiT Bio-Cartridge Retail Kits allow retailers to brew and sell rich, potent compost tea in half-gallon VermiT bags. VermiT Bio-Cartridges are the key to compost tea made with the VermiT Extractor. Cartridges have a dilution ratio of 1:50, which will create 250 water gallons. The included “Awake” and “Frenzy” liquid solutions act as activators of the cartridge when it’s inserted into the VermiT Extractor. The cartridge is for one-time use and lasts up to two years after purchase. The 5-gallon Retail Kit includes four 5-gallon VermiT Bio-Cartridges and eight half-gallon VermiT bags (empty).
