I usually don't grow in the summer due to the heat and I'm struggling to get my ass in gear for this winter. I usually have about 4 varieties I grow, blue oysters, pinks, lion's mane and pioppinos.
Neat, I imagine one with slits in the side would be similar to fruiting in a 5gal bucket where you tape off the holes to keep moisture in. I recently read an article on growing mushrooms in large columns of substrate with egg carton material wrapped around the outside, it wasn't very descriptive but I thought the idea was cool.
