If you drink coffee (or can get the grounds in bulk from a coffee shop), an 8-ounce package of the Coffee Cultivator makes a great, fun way to recycle used coffee grounds, filters, and all!

With this starter culture, you can fill any container with a lid day after day with your grounds … and soon, you will be cooking up some tasty oyster mushrooms to celebrate your willingness to help the environment! Detailed directions are included.

This item is perfect for break rooms and employee lounges, where the culture can be mixed in periodically into a paper and coffee composting bucket. It will eventually fruit and produce edible oyster mushrooms! It also makes a great gift for any occasion.
