Depends on the species. I'm not a big fan of it for cubensis. The gourmet growers use it more.

SPENT coffee grounds are an awesome source of
nutrients. it will increase your yields exponentially,
BUT will also increase your risks of contams, as
wet coffee will grow contams very fast if it is
exposed to them before full colonization.
i have also stopped using it though, at least in
my bulk sub, i still use it in my soak and simmer.

I soak my wbs in weak coffee seams to be :thumbup:

Stays out of my substrates and spawn. I had a bit of a contam problem with it and coir  took out the coffee mean green was gone :shrug:

I would let my mix sit so that contams could germ, pc for 2 hrs, & still not be 100% so I quit using them.

Exponentially! Awesome! If it's exponential, then I should go back to using it. Apparently I wasn't doing it right.

You're not supposed to sterilize bulk substrates.  Doing so leads to an increased rate of contamination. Besides, mold spores are killed by temps above 135F, so allowing them to germinate is a non-issue.  Your problem was sterile procedure during or after inoculation.

Worm castings are in no way, shape, or form the equal of coffee grinds as a food source for fungi, and it's not just about nitrogen. There are many other compounds as well in a good supplement, coffee having over 200.  Mushrooms are not plants.  Disregard NPK when dealing with fungi.

Small amounts of spent coffee grinds of the nature of 5% to 10% will increase yields by 25% or more.  Commercial growers may be more successful at making it work then cubensis growers because of their higher level of experience and attention to detail, coupled with a refusal to cut corners.

Advising one to avoid coffee grinds despite the benefits, is like telling a kid to keep his tricycle forever because switching to a bicycle might cause him to skin his knees as he learns something new and more challenging.

Hmm...I have a monotub colonizing right now w/ coir/coffee/verm/gypsum as substrate...I thought coffee grounds would increase yield by a ton? But people here are saying they don't use them? I thought coir/verm by itself would only yield 1-2 flushes and not really yield that much? So what SHOULD be used in place of spent coffee grounds?

I have been debating on using horse poo and coffee grounds for my next bulk grow.  I think I might go with the coffee grounds simply because I have leftover ones and I won't have to go gather the poo. 

I had contamination issues with horse poo last time I tried it.  I must not of pasteurized sufficiently.

Coffee ground has it all; minerals, phosphorus, proteins and cellulose.

Its mildly acidic, has some PH buffer capacity, average PH of 6.9.

As for contams, its pretty safe and fantastic considering to how loaded it is with nutrition.

Coffee ground is just awesome...

Last time I used spent coffee grounds with my coir substrate, I removed 2 handfuls of coir for the top layer and mixed the coffee in with the rest. I used 5 jars of spawn, one brick of coir, 2 quarts of vermiculite, 4.5 quarts of water and a cup of coffee grounds. With a high ratio of spawn to substrate, it only takes a couple of days for intended mycelium to take proper hold of the substrate, and with no coffee in the top layer, the straight coir acts like a shield against new contaminants as mold spores refuse to germinate on it. It worked for me several times. As I am not a coffee drinker, I don't use it much... But I did notice a denser pin set with no noticeable size decreases. Simple and effective.

Are spent tea leaves a good substitute for coffee grounds?  I personally am more of a tea drinker than coffee.

I was actually mixing them in with the grain jars. It wasn't enough to bog down the grain. It was more like the grain was "seasoned" with them. Then I was also cooking the grain in diluted coffee. I was also doing this at 3,500ft elevation which made the mycelia grow slow as hell which would have made them more prone to contamination. The cultures that didn't contaminate were great fruitters. Honestly the only bulk runs I've done successfully have been with live compost.

So was I then simply using the grounds wrong? I mean the thread that made me start using them even had petri dishes enriched with it. Was it the elevation? I mean could that have been enough to lose 10f at 15psi?

M11, tea is great for growing mushrooms. You can even put the full tea bag with the paper into the substrate.

I´m doing some trials growing oysters in 100% coffee grounds used directly from a coffee shop (no pasteurization but used the same they they passed through the coffee machine) and although i got contams in some bags, it looks promising

Here a picture of the oysters growing on the coffee grounds:
