Growing mushrooms on spent grain

[Burlyman]

I'm wondering if it is possible to grow mushrooms on spent grain?
Anyone tried this before or had any success in doing so..
It is something that I've been thinking about for a while now and am keen to know more about.
Cheers!

Where will you grow them?
I had to stop putting my spent grain in the compost as it attracted rats

 

[Burlyman]

I was thinking in bags in the shed.. maybe make a little mini-greenhouse for them that is temperature controlled..?

I am going to have a go at it quite a few brewers do apparently.

Which variety are you thinking..?

Spent grain starts to ferment and stink after a couple of days, and gets quite warm. Probably great for mushrooms. Don't add it you bread unless it is absolutely fresh, by the way. It utterly destroys the gluten as I found recently to my cost.

I think they need temp control in the cool side and artificial light cycle to mimic shorter autumn days. I seen a programme where they were grown in a shipping container which was like a giant brew fridge.

Oyster mushrooms would be the obvious choice. They will grow on consumer and huge range of substances. Coffee grounds are known to work well. The grain idea is very interesting.

As mentioned above, be careful where you grow them as spent grain is rat utopia.

When Geordie beer kits were located at North Shields on the banks of the Tyne they dumped the used grain on the rocks at the back of the premises at low tide. Within seconds the area was infested. Great fun for the local kids who had air guns

Oysters initially but there is quite a choice.
This is where I first got the idea.

What a great idea ,
You can buy a syringe of spawn for about £10 ,which would get you a few pounds of mushrooms on a few kgs of grain .

I dried a lot of mushrooms last autumn, absolutely brilliant, like mushroom chips, strong flavour and sure I read recently that they are available commercially.
Here is a recipe for an Imperial Stout using mushrooms, not something I would have considered but can imagine the strong flavour of the dried mushrooms coming through.
Something to consider when either picking or growing mushrooms.

I have to throw my spent grain in the bin as I have no way to use/recycle in my garden and I have to say that the smell is absolutely repulsive if I don't double bag it!

I can't imagine what it would be like after a few days open in a shed ...

Some useful information here. With success.

Can you crop the spores from supermarket fungi

No, you buy the spores. This is an Aussie brewer going at it full tilt.

I believe you can yes.
