Here we are offering 12 quart jars of Sterilized Grain Spawn. Each jar has a self healing injector port for inoculation and a 0.45um gas exchange filter. The rye berries are moisture content guaranteed. The 12 jars come sterilized and ready to inoculate right out of the box. Simply inject 2-4 cc or ml. of gourmet mushroom solution or LC. Allow to colonize for 10 days or until fully colonized. You can then use the jars as grain masters, for grain to grain transfers or spawn directly to a bulk substrate.
