Freshly Made With Quality Ingredients 

Good ingredients make for good substrates. That is why we only use 100%, natural and organic ingredients. 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. 


Please aim to use grow kits or substrate as soon as you have received them. If you plan to use them at a later date, they are best stored in the fridge. Each item will have an expiration date of up to 2-4 months if stored correctly.
