A while ago I purchased an Espresso Oyster Mushroom kit from Grow Organic. I started saving our coffee ground until I had the three gallons needed for the kit. It took me few months to save up enough coffee ground. If you’re interested in doing this make sure you start saving coffee ground way in advance. You can store them in the freezer to keep them from getting moldy.
It’s quite easy to get the mushroom kit going. You’ll need: a 5 gallon bucket, mushroom spawn kit, three gallons of coffee grounds, and filtered or distilled water. First you want to make sure your bucket is clean, you don’t want any stray bacteria mucking up your mushrooms. You want to drill drainage holes in the bucket and maybe in the sides of the bucket depending on how full it is after mixing all the ingredients.
The next step is to mix the coffee grounds with the mushroom spawn. The directions state to pour coffee grounds into bucket and moisten them, then add spawn and mix. I added half the coffee grounds, wetting them with some filtered water, then I added half the spawn and mixed well. I proceeded to add the remaining coffee and spawn and then I mixed the top layer. Then I made sure the whole lot was damp but not soggy wet.
Needless to say mixing the all of the ingredients well in the bucket was not super easy. It would be much easier to mix it all in a shallow square storage tote first then transfer to the bucket. I’ll remember that for next time.
Then you place the plastic dome provided with the kit on the bucket and place it in a shady area that receives some light. If the amount of coffee and spawn in your bucket does not come up to within a few inches of the top of the bucket you’re supposed to drill a few holes in the sides of the bucket for ventilation. The directions say to mist with water every day and you should have mushrooms to harvest in a few weeks.
It really is that easy. I spent about 15 minutes to get the kit going, that included drilling holes in the bucket. I’ll be letting you know when I harvest the first mushrooms from this kit. It will be interesting to see how many I harvest. The directions say that you can use the spent kit a few more times my inoculating more coffee grounds. It should be an interesting experiment!
