Fig. 19. View of a Dutch standard growing room containing, as an average, 180 m2 of growing surface in shelf-beds. This picture of a first break of an off-white strain of full—grown compost out of a tunnel was taken in 1973 in one of the growing rooms of the instructional farm at the Mushroom Growers' Training Centre in Horst, the Netherlands.
What husband Pieter, above all wanted to show here, was that even back then, in 1973, we covered almost every square inch of growing surface! There is no room left for more. Because then it hurts the quality.
This was the very best learning experience for all our thousands of students. They got a tour through the instructional farm at the Mushroom Growers' Training Centre, as part of the daily practical knowledge exchange.
