The box (currently Leo Boxes because there seem to be a few around our place comes with the grow bag containing the substrate and casing already in place. When you get it you simply open the box and the plastic grow bag. Pull the plastic bag vertical and then put an elastic band around the top so that about an inch hole is open for gasexchange but not enough to let too much moisture out. Then wait, 5 to 7 days pins will appear, another five to seven days and the mushrooms are ready. You let the box sit for 5 days. Water the casing material and put the rubber band back and wait for the second flush.
Sound easy enough?
As for delivery, I can stick the box on a regional bus for single orders. If there is a group of people wanting them then I will deliver to a convenient watering hole and run everyone through the process. Open to suggestions, Sisaket, Ubon or Surin are fine for delivery, Buri Ram is getting a bit far. I am in Sisaket.
