Uncle Myc's | Rye Berry Grain 100% Sterilized Mushroom Spawn Bag 2lbs

A 2 lb bag of rye berries, sterilized and hydrated, ready for you to inoculate. Rye is a standard grain for building spawn that you later mix into a bulk substrate.

The bag has a self-healing injection port, so you can add a liquid culture or spore syringe without opening it, and a filter patch for gas exchange that keeps contaminants out. Uncle Myc's says it suits a wide range of gourmet and medicinal species.

Tip: wipe the injection port with alcohol before and after each needle goes in.

Pairs with: Uncle Myc's CVG Supplemented Bulk Substrate 4 lb, Uncle Myc's Master's Mix Bulk Substrate 4 lb.
