Sweet. Thanks for the info BlueGrower. +5 for the nice grow.
How much coffee grounds could you get away with in a quart jar of grains? I usually just soak and simmer the rye grain with dilute coffee -some coffee grounds end up in my jars, but not many. I was wondering if you could do a 1:4 ratio of coffee grounds to grain. I would think if you added gypsum like you should (maybe 2 teaspoons per quart jar) it would prevent clumping of the coffee grounds and rye.
This would prevent any contaminant concerns with coffee grounds, because they would be sterilized with the rye. It would also be a very easy way to introduce coffee grounds into your substrate. It would spawn right in with the grains.
What say you?

To address a few points from above:
Coir is the equal of horse manure for cubensis. Add coffee to the coir and it's superior. I have horses and cows, so use that, but when I lived in Seattle, I used coir. Use what you have available.
Tea leaves are no replacement for coffee grinds. They come from a totally different plant.
Use liquid coffee in grains. Using coffee grinds will slow performance. Coffee grinds are a bulk substrate additive.
Adding coffee grinds to a bulk substrate won't increase yield by a ton unless you're growing five or six tons. They'll add 20% to 30% if used properly.
Always properly pasteurize bulk substrates which include coffee. Proper pasteurization means heating the hydrated substrate until it's 140F/60C at the center and then holding it there for 90 minutes. Spawn when cool. RR

"Nitrogen supplements in general use today includes corn distiller’s grain, seed meals of soybeans, peanuts, or cotton, and chicken manure, among others. The purpose of these supplements is to increase the nitrogen content to 1.5 percent for horse manure or 1.7 percent for synthetic, both computed on a dry weight basis." -Six steps to mushroom farming College of Agricultural Sciences Agricultural Research and Cooperative Extension Daniel J. Royse1 and Robert B. Beelman2 1Professor of Plant Pathology, 2Professor of Food Science, The Pennsylvania State University, College of Agricultural Sciences,
EFFECT OF ORGANIC NITROGEN SUPPLEMENTATION IN PLEUROTUS SPECIES.
R. C. Upadhyay, R. N. Verma, S. K. Singh and M. C. Yadav National Research Centre for Mushroom, Chambaghat, Solan - 173213, HP - India <rc_upadhyay@hotmail.com> The nitrogen content of mycelium ranges between 3 to 6%. Cereal straw used for cultivation of oyster mushroom is a poor source of nitrogen (0.5 to 0.8%) and at the time of fructification when most of the nitrogen is utilized for mycelial growth, the depleted nitrogen in the substrate becomes inadequate and limits mushroom yield. In the present studies seven different organic nitrogen sources: wheat bran, rice bran, soybean floor, de-oiled soybean meal, mustard cake, cotton seed cake and cotton seed meal were evaluated for their effect on mushroom yield. Cotton seed cake and de-oiled soybean meal gave significantly higher yield than unsupplemented bags. Mustard cake supplemented bags gave the lowest yield, which obviously was due to its anti-fungal properties. Cotton seed cake and de-oiled soybean meal were further evaluated – on a 1, 2.5, 5, 7.5 and 10 % per dry wt. basis, to find out the minimum dose for optimum yield. Cotton seed cake - 2.5%, 5%, 7.5% and 10% - gave similar yields although significantly higher than 1%. However, 1% soybean meal was found the best, and all higher rates of supplementation gave lower yields. It could thus be concluded that addition of 1% de-oiled soybean meal and 2.5% cotton seed cake are the optimum doses for these supplements to enhance the yields of P. ostreatus var florida. Their supplementation also gave higher dry matter than unsupplemented bags.

yeah , i guess in my shit-tons of experience not ... always thought hpoo and its perfect balance of nitrogen and microorganisms were the best ... certainly seems so ... tired of all the flip flop bs im hearing

Oh my! that's alot of input.. Thanks too all of you for the info! This has became UBER helpful and I will definitely take some of your guys advice! I hope this has helped many others as well I think I may try acouple of different ideas and see what works best.. I'll try to put up a grow log of some tubs with coffee and with out in the near future!

Exponentially! Awesome! If it's exponential, then I should go back to using it. Apparently I wasn't doing it right.
maybe. fuck if i know. maybe you missed something.

If you were to simmer some coffee grounds for 30 minutes, pour out the water, and then use those grounds in your coir/verm/gypsum substrate, could you just pasteurize the grounds with your coir/verm/gypsum via the boiling water tek?
