Gypsum for mushroom substrates

Gypsum is the unsung hero of mushroom cultivation! This calcium sulphate powerhouse strengthens your substrate structure, preventing it from turning into a soggy mess while your fungi friends colonize. It also boosts calcium levels, promoting robust fruiting bodies and healthier yields. Whether you're growing oysters, shiitake, or lion's mane, a sprinkle of gypsum keeps your substrate perfectly balanced—firm enough to support growth, yet breathable enough for optimal colonization. Give your mushrooms the structural support they deserve!
