Last month I entered an earth day contest on twitter with @TheMushroomChannel and won an oyster mushroom growing kit. The kit is made by a company called Back to The Roots, you can find more info here: Mushroom Kit Info .
The first step was to soak the mixture in water for 12 hours and then after that all you have to do is mist it twice a day and after 10 days you harvest the mushrooms. I am on day 2 of mushroom growing. I can't wait to see the mushrooms pop out of my box. :) Plus, after that I can turned the box around and open that side up and get a 2nd harvest. Here's what my kit looks like right now. I will keep you updated as my mushrooms start growing.
