Mushrooms are a fairly responsive crop. They grow about 4% every hour, which doubles their size every 24 hours, essentially, but when there was the oversupply and they were throwing away product, they cut production back. It takes about a month from beginning to finish, from when a mushroom starts growing, so when they had the oversupply and were throwing them away, they were also adapting and reducing production in order not to have throwaways.
With that, the oversupply situation ended and they answered that problem, but there have been some who have suffered more than others.
