Blue Oyster mushroom

Blue Oyster mushroom kits are the easiest of all of our Grow Your Own kits. They are very reliable producers and tend to yield large flushes of mushrooms. They are also the easiest kit to get subsequent fruitings and should reliably produce a second flush or more of mushrooms.

That’s not mold; that’s mycelium! Your kit includes an amended sawdust block fully colonized with mushroom mycelium. It may appear covered with a soft, white, mold-like substance – that’s the mushroom mycelium! It is completely normal. The mycelium of some species is more prominent than others.
