Attach the air pump to the aerator and place it outside the bucket. The air pump and aerator will supply oxygen to the water to allow microorganisms to breathe. Place the tea ingredients inside the milk bag.
Proceed to make the tea
After connecting the aerator and air pump to the bucket, proceed to create the compost. Fill half the bucket with mature compost. It is recommended to stay within this limit and don’t fill it up. This allows the compost to be loose and the aerator to work.
Fill the rest of your bucket with water and ensure it is enough so the mixture can fill the bucket. Leave roughly 3 inches of headroom at the top of the bucket to allow you to stir the tea without messing up the process. Stir the mixture gently.
