  • Inject Your Bag

    Inoculate your bag with your choice of mushroom genetics – 2-5ml will do the trick.

    Let the mycelium grow – once 20% of the bag is covered, break the mycelium and mix it to speed things up!

Frequently Asked Questions:

What Shipping Do You Offer?

We offer next day delivery for all orders. This is free when you spend £50 or more (check out our Delivery page for more info). All orders are dispatched same day (for in-stock items).

How Fresh Are Your Substrates/Grains?

We make small batches daily, multiple times a day. These batches are then sealed in our clean room and cooled down to room temperature for 24 hours before being dispatched. This constant supply means we will always have the freshest substrates and grains available.

What If My Bags Contaminate?

We track all batches to ensure any contamination risks can be monitored and eliminated. Although unlikely, if for any reason your bag arrives contaminated, or contaminates before you inoculate your sub or grain, we'll replace the affected bags straight away! (see our returns policy for more info).
