A growing room consists of long, aluminium shelves stacked one on top of the other to make more efficient use of space. As the mushroom compost is filled into these shelves, a layer of peat is applied to the surface in order to help the substrate maintain its moisture.
The environment inside the growing room is then carefully controlled to provide the optimum conditions for the mushrooms to grow. During the next six weeks the levels of temperature, humidity, oxygen, carbon dioxide and the speed of the air movement are carefully monitored by the grower with the aid of purpose-designed computer systems. We bet you never thought mushroom growing was so complicated!
When the mushrooms reach the desired level of maturity, harvesting begins.
