Bio-Cartridge Retail KitVermi T Bio Cartridge Retail Kits are designed for a retail store to have a convenient way to offer freshly extracted microbe rich solution to their customers. These kits come with everything you need to make Vermi T and a correct volume of labeled containers to refrigerate and sell as finished product. These are not typically sold as a kit to the end user, but rather sold as a ready to use concentrate in half gallon increments. VCBC5RK: includes: (4)
