Sterilised Rye Mushroom Grain Spawn Bag

THE PERFECT STERILISED RYE GRAIN FOR SPAWN PRODUCTION

Our best-selling, optimally hydrated organic rye grain is one of the best options for spawn production. It is superior to many other grains because its larger kernel size and high nutrient content provide a massive amount of energy for the mycelium to thrive.

Our grain spawn is highly versatile and can be used with a variety of different mushroom species, from exotic, functional, or gourmet fungi.

THE BENEFITS

• Perfect foundation for starting your mushroom cultivation

• Supports rapid colonisation for fast, healthy mycelium growth

• Guaranteed to produce mushrooms or we’ll replace your spawn free of charge 

• Save money by growing your own mushrooms at home

• Little space required to grow & is discreet with no smells

• Grow fresh, delicious mushrooms you can't find in the shops

HOW TO USE

The process is simple:  

1. Inoculation: Simply inoculate with 5ml of gourmet culture or spore solution via the injection port and leave to colonise.  

2. Colonisation: Within 3 to 4 weeks, the grain will have fully colonised the substrate and be ready to spawn to bulk.  

3. Spawning: Once your grain spawn is fully colonised, simply mix it with our Sterilised CVG Mushroom Substrate Bag in a MonoTub, perfect for growing exotic fungi or dung loving fungi. Alternatively, if you’re growing gourmet mushrooms, you can mix it with our Bulk Substrate – Hardwood Mix to create a high-yielding fruiting block. For therapeutic fungi we recommend a 2:1 bulk substrate to spawn ratio, but if you’re growing gourmet mushrooms we recommend a 6:1 wood-based substrate to spawn ratio. 

Gone are the days of having to trawl through decade-old forum posts to figure out the fascinating but often confusing science that is growing mushrooms. Our step-by-step, easy-to-follow guide ensures a successful harvest, eliminating guesswork and making the whole process a breeze.  

INGREDIENTS

Great mushrooms begin with great spawn. That is why we only use 100% natural and organic grain in our spawn. We only use high-quality, natural ingredients for our products, specifically selected to support the optimal growth of mushrooms.

Our optimally hydrated rye grain is the most reliable grain spawn available. It’s ideal for spawn production because its water-holding capacity and structural integrity ensure the kernels stay individual rather than clumping, allowing for maximum surface area for the mycelium to attach. We first soak and then cook our grain, carefully hydrating it to around 50% water content before sterilising the bags in a computer-controlled steam autoclave for 2 hours at 121°C.
