Sterilised Milo (Red Dari) grain bags will allow you to quickly and easily make your own mushroom grain spawn. Milo, otherwise known as Red Dari, or Red Sorghum, is a uniform, nutrient-rich grain that’ll provide plenty of inoculation points for your mycelium. 

Our Milo grain is perfectly hydrated and dried to reach an ideal moisture level. Then, it’s bagged up into premium Unicorn mushroom grow bags before being sterilised inside our medical-grade autoclave for 2 hours 30 minutes at 121º.

How To Use

To use your sterile Milo grain bag: Whilst practising aseptic technique, use the included wipe to clean the bag’s injection port, prepare your mushroom genetics syringe (sold separately) and sterilise the tip of the needle. Then, insert the needle into the injection port and inject 2ml-5ml of liquid inside. Need more info? Read our sterile grain bag instructions. 

Storage Instructions

All sterile bags should be removed from any delivery packaging immediately after being received. This allows the filter patch to breathe, which prevents moisture from passing through the filter and drawing contaminants into the bag.

We recommend storing the bags upright, in a cool, dark place like a cupboard, for up to 7 days to observe that the bag is sterile before use. Do not store in the fridge. All bags can be stored for up to 6 weeks, but should be used as soon as possible. Our sterile bags are covered by our sterile guarantee, so in the unlikely event that your unused bag contaminates within 30 days of receiving it, please contact us for a replacement.
