Our Expert's Opinion NEW

Tony, our resident mycologist, has this to say.

Pros
  • Fast Colonisation - A high surface area to volume ratio means more inoculation points for the mycelium.
  • Sufficient Nutrients - Provides a rich nutrient profile that supports vigorous mycelium growth.
Cons
  • Clumping - Breaks down more easily compared to rye or oats, potentially leading to clumping.
Tips
  • Reduce Contamination Risks - Shake the bag gently before use to redistribute moisture and prevent wet pockets, which can promote bacterial contamination. Let the bag fully colonise before handling and only open it in a sterile environment, like a still air box or in front of a laminar flow hood.
  • Kickstart Colonisation - If your bag stops colonising and stalls, it’s usually because of the positive pressure on the mycelium. Turn the bag on it’s side and this will change the pressure point and allow the mycelium a route to grow.

Product FAQs

How do I use this White Millet Grain?

Inject your mushroom spore syringe into the White Millet Grain via your self-healing port and let the mycelium do its thing. Once the magical mycelium has colonised the White Millet Grain and it is all white, then you can mix it in with your substrate.

Of course this is all assuming that you want to grow mushrooms but you could also… fill a balloon with your grain and use it as an eco-friendly stress ball. Half-fill a container with your grain and use it as some homemade maracas. Hell you could even feed your grain to the birds. But whatever you do, for the love of God - do not use your White Millet Grain to be growing magic mushrooms !!

How long does this White Millet Grain last?
White Millet Grain will last approximately 6-12 months in a cool, dark environment. We recommended to store it in a sealed container ensuring that it is suitably protected from pests.
