Our 1lb PureSpawn bag features Certified-Organic hard red  wheat, triple-washed and simmered with gypsum for the perfect mineral-rich hydration that mycelium craves. Hand-packed in Florida and sterilized at 15 PSI for 120 minutes, each authentic Unicorn 4T bag is equipped with a 0.2-micron filter patch and a self-healing injection port to ensure a 100% sterile, professional-grade start for your mushrooms. Using hard red winter wheat provides more inoculation points than standard grain, leading to faster colonization and a cleaner, more robust canopy.
