My son and daughter in law received a box containing a grow your own mushrooms kit for Christmas. Unfortunately, it needed to be started by a certain date which was one day before they were due to leave on a vacation. After the kit was started, it then needed to be watered every other day. So I got custody of the box for two weeks. Well. I started the procedure which involved opening the box, then opening a large plastic bag which was filled with compost or some other heavy stuff and mycelium, and a smaller plastic bag filled with topsoil. The topsoil went on top of the stuff in the big bag and the whole thing was watered. Then it went into a dark 70 degree place for a few days. So I watered and watched and watered and watched and lo and behold, white stuff grew up through the topsoil from the stuff underneath, Then little white dots appeared. These would become mushrooms. The directions said they could double in size every day. Boy, were they right. In a couple of days, the box was 3/4 filled with small mushrooms which did indeed double in size every day. The kids were not due back yet so I picked a couple of the biggest ones. One egg and one mushroom made a nice omelet. Another omelet the next day. A few mushrooms sliced and eaten for a snack. One giant mushroom eaten like an apple. The mushrooms still growing. The travelers returned. My son caught a cold on the plane and we went into a cold snap. He couldn't come for the ever growing mushrooms. I couldn't keep up with them. I can only eat so many and I reached my limit. So I picked them all, quartered and blanched them and froze them in a gallon size baggie. Now I see there are more tiny white dots forming. This cycle could continue for 90 days. I may keep this box and get a new set for my son. He should have the joy of growing mushrooms from the beginning, right?
