It is the ideal container to place the different ingredients to make compost tea. The mesh allows water to extract and dissolve nutrients while retaining large particles of the humus/compost. The Tea bag has a carabiner with which we can hang the bag to the water tank in which we are making Tea. Insert the ingredients into the bag, roll up the neck of the bag using the clips and close it. Do not forget to massage the bag so that the ingredients come into contact with the water so they don't generate dry material zones. It is very important to clean the mesh after each use.
