Dry Pasteurized Compost

Many of you hobby mushroom growers have been asking us to sell un-spawned regular agaricus mushroom growing compost. We now have it available in a dehydrated format. This compost is our standard straw and manure based mushroom growing compost. The material is composted for around 30 days and then pasteurized. We then spread this compost out to air dry it and later we bag it and send it back to be pasteurized a second time.

In the second pasteurization the compost is placed in a sealed growing bag with an air filter patch. The bag and filter patch help keep the compost clean. The holes in the filter patch are large enough to let air escape when the compost is being pasteurized, and yet keep out a lot of unwanted contaminants. While the large holes in the filter patch let out the gases, when the bag is being cooked it can also let in some small spore contamination later. Be aware of this and consider it in your use of the product.

This product can be used to grow many varieties of wild mushrooms, but not all mushrooms will grow on it. Experimentation will help you find out what varieties will work. We are including with the compost a small bag of Peat Moss Casing, which can be used to case anything you attempt to grow. These items are considered raw materials for growing some mushroom fungus. To use them correctly you will have to know some of the basics of mushroom growing. This is not a do it yourself kit, but the raw materials to do part of it yourself. You will need to learn how to use this product to grow mushrooms yourself.

The dried compost will have to be wet before using it.

(Note: This is fresh and new compost to be seeded with your own mushroom spawn to grow mushrooms. It is not spent mushroom compost that mushrooms have already been grown on.)
