Mushroom Grow Bags containing growing media inoculated with mushroom spawn. The white material inside the bags is the "mycelium", which has "colonized" the growing media. These bags are kept in the "spawn room" until fully colonized, then moved into the grow-out room.

Rows of Mushroom Grow Bags beginning their first "flush". Oyster mushrooms begin to grow through holes in the poly bag and form a cluster. Temperature and humidity conditions are kept just right in the Grow Room to encourage proper growth patterns.

These Oyster mushroom "clusters" are ready for harvest. These are the yellow variety. We have also grown pink, blue, gray, and brown varieties. Shitake mushroom are also being grown in a similar manner. They take somewhat longer than the oyster mushrooms but can sell for a higher price. There is a great demand for both!

Oyster mushrooms wholesale at prices of $ 2.50 a pound to as high as $ 6 and $ 7 a pound! A 30x129 standard mushroom production unit can produce over 50 tons of oyster mushrooms per year!

Cropking now has three different size mushroom systems available.
The largest system is a 30' x 129' unit that holds 1920 double hung bags in the grow room. We also have a 30' x 69' that is designed to be expandable to the full 129' length. The 18' x 49' unit holds 216 double hung bags and works great to add an additional product line to a produce business.

At the heart of our systems is the Mushroom Steam Pasteurizer which uses aerated steam to cook the mushroom growing media. This innovative machine eliminates much of the heavy lifting and dangers of other methods of pasteurizing the mushroom media.
