We start our oyster mushrooms in coffee grounds

January 8, 2011 | By | Comments (3)

As a departure from our on-site projects, I decided to take the Back to the Roots oyster mushroom growing kit home and get my twin teenage boys involved. The guys thought it sounded like fun, and also, the kit needs to be misted twice a day to keep the mushrooms happy, and I figured the weekend misting would be easier to handle this way.

The kit consists of the outer cardboard box, an inner bag of used Peet’s coffee grounds that have been innoculated with mycelium, brief instructions, and a small mister bottle.

We followed the instructions, with a few modifications. To get the box open on one side, we found that we needed to cut through the dotted lines in the cardboard box with a small knife. Then we slit a cross through the bag of mycelium-inoculated coffee grounds that’s inside. The directions don’t say how big the cut should be, so we just took a guess.

At this point we pulled the bag out of the box (“looks like a Frappuccino!” Jasper noted) and soaked it overnight in a bucket of water.

Turns out that the bag floats, so we weighted it with a bowl.

In the morning, we shook the bag off, stuck it back in the box, and set it on the kitchen counter.

So far, so good! Now we start misting. We’re supposed to have mushrooms to harvest in 10 days.

    Howdy guys, im a coffee bean addict. I personally was looking over this information and absolutely appreciated it.
    It consists of numerous really nice ideas for me to process.
    I have got to say, I’ve become lonely nowadays as my best friend is not here with me. Surfing internet sites gives me a tiny piece of mind . I would like to thank you because of this beneficial on line blog which will will help pass the word in regards to coffee / espresso even more! I actually was itching to know if you provide an email listing so I can at all times keep current at this site.

    That’s awesome. I’ve been wanting to grow my own mushrooms for a while.

    Looking forward to seeing the results. You’ve got me inspired.
