Hi All,

I am a busy home-brewer and I was thinking it might be beneficial for me to grow mushrooms (probably oyster) from the spent grain - rather than just chucking it out.

Has anyone on MyBB grown mushrooms, what was your experience? Worth it or not? What was your mushroom setup like?
 
Do you enjoy chemistry? Are you able to work in a sterile environment?Do you have a pressure cooker?

Its not easy but its very rewarding.Your technique has to be spot on to reduce contaminates.

Spent grain..that will need to be sterilized first.Will it still look like grain afterwards though?I used to use popcorn seeds.

I used to sterilize red sorghum in jars. Worked well. Used cooler boxes to grow in and a humidifier to control humidity (obviously :) ). They grow so easily.

Very easy and very rewarding :) But need to follow guidelines to the T in the initial stages for best results.

From what I have read if you want to produce en mass then the sterile environment is more important - the reasoning for this is simple. Nature is seldom sterile, yet they grow in nature.

What problems did you have with contaminates?

The only part that requires sterile environment is the innoculation of the grain.I had to do this inside a glovebox.I messed this part up and one or two jars got contams.

They grow in nature, but that process of faking it inside doesnt translate well when you dont have natures microbes doing the 'cleanup' for you like how it works outside.

Well the grain has ~70C water pump through it and ~46C is hot enough to remove 99% of bacteria. So that shouldn't be an issue as long as it's done soon after the grain is used from the brewing process, I suppose one would just need to sanitize whatever container was to be used as well.

What was your setup like?

What kind of container did you use to grown in?
I've seen that the coffee ground guys grow in what looks like material bags hanging from hooks in a climate controlled room - obviously more "pro" that I would be going for.

Tried it once. Can't remember what happened after eating them...
