If you like mushrooms Dominion Seed Co. has a kit to grow Pearl Oyster Mushrooms indoors. When I first tried one out the cost was $17.00... now $35.00 but well worth it. Especially done on the BBQ, in tinfoil, with butter, served with a nice medium rare Striploin... Baked Potato... Veggie optional 😀
