What Is Mushroom Grain Spawn?

Grain spawn is a little known secret weapon of the world of mushroom cultivation. It’s made from sterilised grains that have been inoculated with a live mycelium culture.

Grain spawn contains a lot of energy for the mycelium to consume. It’s a bit like rocket fuel for mushrooms. Once it’s added to your substrate it takes off like wild fire. 

Mother Nature works her magic using spores but in a controlled environment you need to tip the scales in your favour by using clean high-quality grain spawn so you are doing your best to ensure success. 

Make Spawn With Sterilised Grain Bags

Each sterilised grain spawn bag has been carefully prepared by hydrating whole oats in a gypsum bath for 24 hours before sterilisation. 

The bag itself features a 0.2 micron filter patch to facilitate fresh air exchange without the contents becoming contaminated. 

Additionally, the self healing injection port allows the user to simply inoculate the grain using a liquid culture syringe with minimal risk of contamination.

Sterilised grain spawn bags make it possible to produce your own mushroom grain spawn without the use of a pressure cooker.

Looking For Ready To Grow Kits?

A mushroom grow kit is a block of supplemented sawdust that has been sterilised and inoculated with a live mycelium culture in lab conditions.

It’s really simple to use and perfect for the beginner looking to learn about mushroom growing and how to maintain excellent fruiting conditions.
