What’s Included 

Freshly Made With Quality Ingredients 

Good ingredients make for good grow kits. That is why we only use our 100% natural and organic MS-4 substrate in our kits. Our fourth-generation substrate, this mix of optimally hydrated millet, wood pellets, soy hulls and gypsum has been thoroughly tested and refined. Mushrooms are quite sensitive to artificial chemicals and do not grow well on contaminated substrates. It is for this reason that we only use the finest, natural ingredients for your ‘shroomies’. Giving you the perfect nutrient-rich environment that is optimal for your mycelium to thrive.


Please aim to use your grow kits soon after receiving them. If you need to store them, put them in the fridge. They can last a number of months before they expire.
