10lb Mushroom Grow Bag Bulk Substrate grow kit OMRI Coir/Verm/Gypsum (CVG)

For dung loving mushrooms. Big 10 lb bag, fully sterilized, not just 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 for fast colonization. Sterilized in a 3 mm polypropylene professional grow bag with a 0.2 micron filter patch for air exchange. Sterilization provides better yields and less contamination risk than pasteurization. Whether you are growing in the bag or using monotubs, this CVG mix will yield great results. Each bag contains slightly over 10 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.
