Injection port, All-in-one Grain Spawn & Bulk Substrate. Medium & Large. Fully Sterilised.
 
Coir and manure versions are perfect for growing Coprophilous (manure loving) mushrooms such as Agaricus Bisporus, Coprinus comatus and many other well known species.
 
Our oak hardwood based all-in-one bags are better suited to Lignicolous (Wood decomposing) mushrooms like Lion’s mane, Shiitake and King Oyster etc.
 
Its a very simple process: 
1. Gently ease some air in through the filter patch by carefully teasing the sides of the gusseted bag. 
2. Wipe the grey injection port with the 70% alcohol wipe (wipe is included). 
3. Inject spores or liquid culture via the grey injection port. (we recommend using 3ml for medium bags and 5ml for large bags. 
4. Allow mycelium to colonise the grain at room temperature for approximately 2 weeks, sometimes longer depending on quality and species of spores. 
5. Mix the colonised grain and bulk substrate together (don't open bag) 
6. Allow the mycelium to grow into the bulk substrate. 
7. Fruit using your preferred method - We like fruiting directly from the bag: Cut the top off the bag and introduce to high humidity and fresh air conditions.
 
The mushroom substrate is hydrated and pre-sterilised, sealed in thick strong filter patch mushroom bag and can be stored in the fridge for up to 14 days. 

Each substrate bag is sealed before it is sterilised for 120 minutes at 121ºC and 115psi.
