5 lb Coir/Verm/Gypsum (CVG) Mushroom Bulk Substrate OMRI Grow Bag

For dung loving mushrooms. 5 lb bag, fully sterilized, not pasteurized. Our 'OMRI Listed for organic use' CVG blend comprises solely organic coco coir, fine horticultural vermiculite, gypsum, and water. This mixture is meticulously bagged, sterilized, and heat-sealed. Sterilized in a 3 mm polypropylene professional grow bag with a 0.2 micron filter patch for air exchange. Whether you are growing in the bag or using monotubs, this CVG mix will yield great results. Each bag contains slightly over 5 lbs pounds of substrate of pure CVG, not like some of the tiny bags for sale. Made in Tennessee. We assure the cleanliness of every bag, conducting thorough checks for defects before shipment.
