Totally off topic, but what would happen if you would sprinkle a generous amount of liquid acid on the mycelium one or two days before harvesting.
My guess is as good as yours, but if you think of how the myclieum networks works, one would believe that the LSD would be absorbed into the mushrooms. If contaminates that emit toxins are absorbed, why not LSD? I have thought of the perfect method of growing mushrooms. Grow non-psychedelic mushrooms, and then drip some LSD onto the cake before they fruit, this way, no one will ever know you are growing psychedelic mushrooms. I am forsure trying this soon!
PEACE & LOVE
