I think growing mushrooms could get addictive.
A few weeks ago we visited Feed Bristol a project run by the Avon Wildlife Trust in Bristol for a look at the business co-located on the site. One business, was growing mushrooms on a small scale. Imagine plastic boxes a good 90 x 60 x 60 cm seeded with various types of spawn. Some were located in a polytunnel under the benches and if you peeked, you could see some “sprouting”. We saw the amount of the hard work goes into making the medium on which the mushrooms will grow based on wheat straw.
