Rye Grain MycoBag


Sterile and ready to go, just inject 2-3ml of gourmet spore or liquid culture syringe solution and watch the mycelium grow.


It’s a common misconception that a grain is more difficult for newcomers, don’t believe it.  We first started out with grain and had amazing results, so you will too.  Rye grain spawn or substrate is an excellent choice because it supports countless number of species and many mushrooms love fruiting on it.

Filled with perfectly hydrated rye grain (and some gypsum), these MycoBags come completely sterile and ready for you to inoculate with a gourmet mushroom culture syringe.. The fitted self-healing injection port will keep you safe from contaminants.  But, don’t worry – it can still breath through the HEPA filter at the top of the bag!

  • 1x 1200ml MycoBag of Organic Rye Grain with added Coffee and Gypsum
  • Injection Port and HEPA-Filtered Bag offer excellent contamination resistance
  • Sized for large flushes

Can take around 5-6 weeks to fully colonise in optimum conditions.
Does not come supplied with a gourmet spore or culture syringe or any extras not listed above.
Some wood-loving species like Shiitake will fruit on this substrate.
