How Mushrooms Grow

The mighty mushroom has a unique and fascinating production process. Grown indoors on a year-round cycle, mushrooms always pack a nutritious punch into your favorite meals. Before they make their way to your plate, mushrooms go through a growing process in a highly controlled environment unlike that of any other produce item.

Raw Materials

The substrate provides a nutritional balance of organic material to serve as a growth medium for mushrooms.

Spawning

Mushroom spawn, purchased from commercial labs, is mixed with the substrate.

Bedding

The mushroom spawn mixture is transferred to several hundred beds or trays.

Casing and Pinning

Casing, made of peat moss, is spread over the mushroom bed serving as a reservoir to hold in moisture. During the pinning stage, “pins” of mushrooms push up through the casing.
