mushrooms... [May. 7th, 2010|08:23 pm]
Verminius Rex
I got my oyster mushroom spoors today (60 grams of inoculated rye seeds), so it's time to prepare the substrate and get a couple of containers going. One will be all coffee grounds (with a bit of tea leaves tossed in), the other will be the compost from the city. If there are enough of the coffee grounds left over I'll do a mix to see how that compares.

Right now I have a big pot of coffee grounds with some water on the stove to boil, for about 45 minutes to kill off competing bacteria. I'll do the compost afterwards. Straining a big pot of coffee grounds is going to be interesting. It'll take hours to cool down so I can add the spoors, so it may be late tonight before I get everything growing. Then it may be weeks before there are any visible mushrooms growing.

If the experiment works then I'll see how long the mushrooms grow by topping off the coffee grounds, possibly do another growing method (sterilized straw in a contractor trashbag with slits and inoculated plugs, hung from the ceiling in the basement). Or I may decide that I only need a certain number of mushrooms and buying the occasional box is enough.

Just so you know, boiling a huge pot of spent coffee grounds doesn't smell nearly as strong as a single pot of fresh grounds brewing.

And big thanks to stuology and my parents for helping with the stockpile of spent coffee grounds. You can stop collecting now.

I put two buckets of the city compost in the garage. I had some amazing mushrooms growing in it. I have no idea what kind they are.

That's why I boiled the compost, I don't know a mushroom from a toadstool. Unfortunately the boiled compost is pretty much very wet mud, I may just go with the coffee grounds after all.
