Mini Grow Bags Lesson Package

This package is specifically designed to give schoolchildren the opportunity to get started with the circular economy themselves. Learn how fungi work. How to turn a residual flow into value. How to close the loop.

We've developed a special instructional video explaining how you, as a teacher, can teach students a lesson where we provide most of the materials and the students also have to find fresh coffee grounds themselves. It's certainly fun to use coffee grounds from the school or surrounding businesses.

At the end of the lesson, each student will have a mini grow bag containing the fungus. The gray oyster mushroom will grow through the material in a few weeks and then produce mushrooms. This can sometimes take as little as three weeks, but it can also take a little longer.

As it grows, you can see the mold growing through the coffee grounds.

As soon as the first mushroom buds are visible, the mushrooms will grow into one or more clusters of mushrooms in 3-4 days.

You will be able to harvest approximately 300-500 grams of mushrooms from the grow bag.

After harvesting, the remaining substrate is an excellent material for growing plants. This way, CO2 is fixed in the soil.

Warning: It can happen that it fails because coffee grounds aren't always clean of other molds. A competing mold will then grow. This mold doesn't produce mushrooms, so there's no risk of harvesting the wrong kind.

This workshop can be viewed from various perspectives: practical work in applied biology. Economics: How does a circular business case work. Nutrition: Are mushrooms healthy to eat? Are mushrooms comparable to meat? Biology: How do fungi grow and what role do they play in the soil?

The minimum purchase of this lesson package is 10 pieces.
