Pre-sifted organic peat moss. Shroom Supply peat moss comes pre-sifted of large sticks and clumps. Peat is commonly used as an ingredient in mushroom casings. A common casing recipe is: 10 parts peat, 10 parts coarse vermiculite, 1 part gypsum, 1/4 part hydrated lime.

Sold in ½ gallon increments.

I order my peat moss from here instead of buying it locally because this stuff already comes sifted. I don't feel like making my own sifting screen to sift the sticks out of the stuff I can get at my local shops. If you don't get the sticks out, you will run into contamination issues because the mycelium cannot colonize through them which makes them vectors for contamination. Shipping is always super fast and everything is professionally packaged.
