Did you know that mushrooms grow well on coffee grounds?
That's why we developed the Rotterzwam Grow Kit, so you can turn your own coffee grounds into mushrooms—oyster mushrooms, to be precise. Right on your own kitchen counter. Will you become a #kitchencounterfarmer too?
We've created a special mailing especially for the #kitchen-sink farmer. A series of seven emails packed with video instructions and tips for the growing process.
The grow kit is emphatically not a disposable product. It is carefully assembled in Rotterdam by people distanced from the labor market. It is made from leftover plastic buckets that would otherwise be destroyed and has a recycled cardboard wrapper.
You can choose between a Dutch or English version.




With this growing kit you can convert a 'discarded' yogurt bucket, juice bottle or milk carton into a growing kit for growing oyster mushrooms on coffee grounds.
Using the included (video) instructions, we'll show you how to prepare the packaging for cultivation, how to make substrate from the coffee grounds, and how to ensure a successful harvest. Become a countertop farmer now!
