Further to this, all the testers at Which? found the kits tricky and time-consuming to use, and many of the kits only produced small crops.

Ceri Thomas, editor of Which? Gardening, says:
“Usually growing your own food means you are rewarded with tasty crops at a fraction of the cost of the supermarket. But this is definitely not the case with mushrooms.

“Many of our researchers found that growing mushrooms was a real chore, and didn’t produce anywhere near as many as expected. When it comes to mushrooms, I’d definitely leave the growing to the professionals!”
