Fresh Coffee vs Spent Coffee
    #6710015 - 03/25/07 04:00 PM (17 years, 9 months ago)

I don't drink coffee at all, so I can't really collect my used goffee cause there is none to collect...:crazy:

So I was wondering if I could just buy bags of fresh coffee and put that into my substrate before pasteurizing? The most info I found on this matter is something RR said.

Well since im going to be adding my coffee to my substarte and then pasteurizing isnt that kinda like leaching it?

And brewing the coffee first is not an option, we're talking bulk here, im not going to boil 50 pots of coffee you feel me..

I don't think you'd want to put unused coffee grounds into the mix, even if you were going to pasteurize after, because you'd essentially be pasteurizing your substrate in a really big cup of coffee, which probably wouldn't be good. I don't know, but it would seem that way to me.

I imagine you could do it like this: heat some water up, put the coffee in a pillowcase, pillowcase into the water, wait like 10-15 minutes for your coffee to "brew"(maybe longer, I don't know), then remove the pillowcase and discard the water. Add your coir, castings, and various manures to the pillowcase, then pasteurize.

cofee is very acidic,you will not want to use unspent.
the purpose of the spent grounds is they are less acidic, but by far im no expert,but have put spent/unspent head to head,
its strong stuff, evn spent

Wow double pasteurize, that kinda sounds silly (no offense of course).I can't imagine why pasteurizing it once all together wouldnt work. Maybe Im wrong though.

If you don't drink coffee, try using something else instead, like bagged chicken manure from the nursery. Use it at no more than 1 part chicken manure to 20 parts of the other substrate materials. The reason I say that is coffee is pretty darned expensive to buy for a substrate. If you drink coffee anyway, no problem, but otherwise there are other materials that work as well. Coffee should be brewed before using. You can brew up a pot of coffee, then use the liquid coffee to hydrate your rye or wbs, and save the spent grinds for your substrate.

Well I was going to add chicken manure to my substrate anyways, i just wanted to add some coffee to just for the hell of it since iv'e been hearing a lot about it. Or will the coffee not really matter since im already adding chicken manure?

But from your saying RR it is ok to use fresh coffee as long as i pasteurizing it right, it's just expensive...?

Sure, why not? I must admit though, I've never used it without brewing a pot of coffee first, so you can be the one to experiment. Let us know how it works.

I don't know if it won't work, I just imagine it won't. Think of it this way. Coffee, the drink, is very acidic. When you soak unused coffee beans in hot water, you get coffee. So by pasteurizing everything all at once, you'd essentially be making a huge pot of coir/shit/coffee which would be very acidic. Too acidic to be a good substrate. By using spent coffee grounds, you would be taking advantage of the nitrogen content of coffee, without the nasty PH. If I'm wrong about this, someone please correct me.

C/N ratio of SPENT coffee grounds is about 20/1
C/N ratio of coir is about 80-100/1
Optimal substrate C/N ratio is about 17/1.

Adding SPENT coffee grounds increases the C/N ratio of coir.

Near optimal Ph of a fresh substrate is 7.2 to 8.
Once colonized & fruiting, substrate Ph will start to drop.
Once substrate Ph reaches about 5.4 / 5.7
Mushroom production decreases / stalls / halts.

So, reality is.......
Fresh coffee added to a substrate, combined with hot water pasteurization.
Decreases fresh substrate Ph, below optimal range.

If you add composted chicken manure.
As RR points out, only add 1 part per 20 parts substrate MAX.

It helps to blend/puree chicken manure into a fine SLURRY.
Before adding it to coir.
Which provides better distribution of it, into the coir.
NOTE
Gal's seem to hate thought of blending chicken shit in a blender.
So, wash it well afterwards & DON'T tell them.

But if you treat it like coir, verm, etc- you would not use more water than the capacity allowed. A few drips to a light stream of water should be released when you squeeze a handful.

So, yah if he used way to much water you would get some soup- like anything you added to much water too.

you can get big bags of already-brewed coffee grounds for free at starbucks. if they don't have them sitting out in a basket, just ask about them. part of their pseudo-we-care-about-the-earth-so-use-our-waste-in-your-garden program.

Exactly what I though, but was too lazy to find data for. Thanks Agar.

Haha! CIV put that quote in his siggy..:tongue2:

I also learned that people who don't do drugs don't like the idea off other people using their blenders for pureeing magic mushrooms up without telling them, I don't know why....:confused:

In addition to Starbucks, just about any restaurant such as Denny's, IHOP, or your neighborhood greasy spoon, will give you their spent coffee grinds. Just tell the waitress to toss in filter and all, because the mycelium will munch those too. I once scored nearly a five gallon bucket of free coffee grinds from IHOP that was generated during the hour I was eating my breakfast.

Good idea RR, that is much less work than saving a million small batches of coffee grinds. Heres a substrate mix I recently used with coffee in it if anyone wants to try it, colonization was about 2 weeks:


30 Cups Shredded Horse Manure
16 Cups Vermiculite
14 Cups Coco Coir
12 Cups Wild Bird Seed
4 Cups Organic Worm Castings
4 Cups Garden Gypsum
2 Cups Spent Coffee Grinds
3 Tablespoons Kelp Meal
4 Tablespoons Vegetable Oil
1.5 Tablespoons Hydrated Lime
Water

makes 4 large filter patch bags

Why wouldnt you just add the coffee grounds to a couple liters of water in a pot, boil it and strain out the grinds?

I saw some coir/fresh coffee colonize in 5 days.  You are completely right about the pasteurization leeching the coffee.  Just pasteurize in a cooler or something by dumping lots of hot water in there.  That way there is plenty of water to "brew" the coffee.  If you are worried, just do a presoak with hot tap water and drain it off.  Use a retail 12oz package of coffee to one brick of coir.  Throw two tablespoons of hydrated lime in the presoak and then two more in the pasteurization water.

This will be SO much easier than getting the grounds from the coffee shop, plus you don't have to explain what you are doing with them. :smile:

Tell the coffee shop it's for your azaleas, fuscias, impatiens, camellias, ferns, or blueberries. They all love acidic soil and coffee is acidic as we know.

Terillus- why did you use decaf?

Why the hell did you buy Starbucks? You could've bought a lot cheaper coffee to just throw in your substrate. I don't think coir gives two shits about flavor but to each his own. You've got top of the line substrate plus it won't get the jitters.
