Coffee In Spawn
    #15669819 - 01/15/12 01:51 PM (12 years, 5 months ago)

So I've been snooping around trying to find information regarding adding spent coffee grounds to my spawn. I've done this for awhile but the amount of coffee I was able to use was always very small, but now I have a friend who is getting me a shit load of used coffee grounds from his job.

I am wondering about inoculating straight to coffee. I have seen evidence in my searches that it isn't the best thing. So I am thinking I will mix up rye cakes where half of the flour is replaced with coffee grounds.

Does anyone have experience with ratios like that? What ratios would you suggest to replace some of the grain with coffee?

I usually see coffee recommended at 5-10%. I've seen oysters grown on nothing but coffee, and I'd assume you could grow cubes on it if you used LC/spawn.

You can freeze it to store it. There's usually never a shortage of coffee grounds ime. Starbucks could give you a couple gallons daily.

Not gonna work.  Spent coffee grinds are a bulk substrate additive, not spawn.  If anything, you could possibly replace part of the verm with coffee grinds, but not the rice or rye flour.

I've been using coir mostly for bulk grows lately. Should I pasteurize the coffee the way I pasteurize the coir? (pour boiling water on it) or should I boil it separate and add it to the mix just before spawning?

Also, what is it about coffee that makes it unsuitable for a spawning substrate? Is it not nutritious enough? Will spores not germinate on it?

I home-roast my coffee beans, then hand-grind them to a course grind for my French press...  I sift the fines out and set aside for gifting to friends with drip-coffee makers...  I save my spent course coffee grounds and dry them on a high shelf near the wood stove...  I add to my grain jars at about 1/12th...  Also add 1/4"- (sans fines) hardwood sawdust/chips at 1/12th to my grain jars as well :smile:

I don't think coffee will germinate spores. I think that's what RR meant when he said it's a bulk ingredient.

I think you'll need to have something that's creates air pockets like straw or verm. At least it would probably benefit from it.

If I wanted a coffee mono I would put the coffee in jars, pasteurize it, and spawn some grain to it. I prolly wouldn't make it more than 2 inches thick, because it seems like it would cake together.

Hmm. Okay then. I think what I will do is just use grain spawn like usual. Then pasteurize some coffee and add it to a coir/verm mix like I would usually use and spawn to that.

And use that as a fruiting chamber? I don't need a new fruiting chamber. I'll just be making a monotub.

Interesting... I will start playing with coffee in cakes in the next few months. I just found a good reliable source for spent coffee grounds, I now have about a gallon and a half of spent grounds to start playing with, and nearly unlimited amounts in the future, and I can get unlimited horse poo for free too.  I am ordering my PC this weekend, this spring shall be bulk fun for me!

I'm just guessing because I haven't really played around with coffee much, but I'd add:

5-10% chicken poo, as a nutrient boost
50% straw, to make it light and fluffy
15% verm
25% coffee
a couple handfuls of gypsum powder

If you add straw and verm, you won't need to worry about it caking. So long as you have the moisture content right. I would hydrate the straw first. There's more on additives here.

Just a tip, don't expect great yields from something new. If it works out tho, bonus.

One of my problems is that my tap water has a pH of 8.1, so a bit of spent coffee grounds should be beneficial. Plus, as BRF is cheap, verm is cheap, and coffee and poo is free, I should have very little to lose by experimenting.
