Brown Oyster Mushroom Grain Spawn - 2.2 kg

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. It’ll take off like wildfire once added to your bulk substrate.

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.
