Many years ago I tried adding this to my grow schedule and thankfully it never got to spread spores, never even fruited. Its not that it wasn't a fast grower, it was pretty vigorous (which is likely a big part of the problem) - the mycelium smelled like a rotting carcass and I binned that shit so fast as soon as I figured out what the stench was. I tell everyone this so people are possibly swayed even if lot of people don't have this issue when growing them.
