3lb. Sterilized Rye Grain Spawn Bag

Our 3lb Sterilized Rye Spawn Bags feature:

• Clean organic rye grain
• 3mm Polypropylene bag with 0.22 micron filter patch
• Pre-soaked and simmered to perfectly hydrate and dry the exterior of the grain before sterilization.

Recent grows have shown remarkable results, with mushrooms of impressive size, quantity, and potency!

Each bag is filled with premium organic rye berries, enriched with essential nutrients, and combined with a carefully balanced blend of distilled and mineral water. This mixture is fortified with gypsum, diammonium phosphate (which supports nitrogen release and helps regulate pH) and minerals designed to enhance growth. 

Each bag is equipped with a built-in filter patch for gas exchange and a high-positioned, self-healing injector port for easy, error-proof inoculation.

Guaranteed to arrive 100% sterile and ready to inoculate! Simply add 3-5 cc's of your preferred grain or dung-loving spores or liquid culture. Each spawn bag is sealed and pressure sterilized at 22 PSI. Guaranteeing your 3lb rye grain bag shows up sterile & ready to inoculate.
