Some technical reps have been finding that some growers have been having problems with casing of late.
A wet and stodgy casing can lead to problems for the grower if it goes anaerobic very quickly.
Growers have to keep an ever-watchful eye on the point of connection between compost and casing. Any lapse is attentiveness could lead to a lot of bother down the line.
As ever the chain of connectivity in the mushroom growing process means that quality control in all aspects is of utmost importance.
If one link in the chain is weak it can undermine the whole process, and prove to be costly all round.
