Lockdown mushrooms: growing mushrooms from recycled coffee grounds

Since we’ve been spending so much time at home recently, we decided to try growing our own mushrooms again. If you have read some of my blog posts on coffee and the circular economy here on the ‘cafespaces’, you may well have already heard about GroCycle who I have mentioned before.

GroCycle produce kits for growing mushrooms at home using recycled coffee grounds, alongside helping others to start their own mushrooms farms, and providing various mushroom cultivation courses.

I have tried this before and was impressed with the results. Given I could guarantee I was going to be at home to use the mushrooms, and it seemed like a good activity to entertain the toddlers for a few minutes a day, I decided to try this again.

The box arrived and we made an incision in the inner package and soaked it overnight as per instructions. Then it was just a case of keeping it in a corner of the kitchen away from the light, and spraying it with a bit of water in the morning and in the evening.

Then after a while it’s possible to see changes happening inside the pack, and after a few days, the pace of growing seems to pick up. Once you can see tiny little mushrooms they seems to grow really fast. There is a noticeable difference between morning and the evening.

Then it’s just a case of waiting until they are big enough to harvest and then find ways to cook them.

We are now growing our second crop from this box, so we’re going through the same process again, so it looks like I need to find more mushroom recipes. The box suggests you should 2-3 crops per box, so we may have more after this round too.

From coffee to mushrooms, an excellent way to recycle used coffee grounds, and a great example of how coffee can be part of the circular economy.
