When you get home with your mushroom “log,” find a place to grow the mushrooms where they won‘t be disturbed and they will get ample light; just enough to read the paper by is enough. They don’t like direct sunlight. Find a container for them to grow in; something like an old cake pan is good.
Place the mushroom log in the pan and put enough fresh water to rise about 1 inch
That’s pretty much it. Keep an eye on it every day. After mushrooms start to grow, mist (spray water) them morning and night. When they get bigger mist more often.
Harvest when the mushroom starts to open up. The vale on the outside edge will skirt the mushroom and eventually start to turn a little bit up [maybe about the 7’ o’clock position. This is the optimum time to harvest.
After harvest, remove from water and set up on a shelf to dry. This drying will take about a week or so.
To grow another cycle soak the log in water for 2 hours to re-hydrate, then start again. the re-start should flush again in about 2 weeks. Repeat up to 4 times if conditions are favorable.
