Great White Monster Magic Mushrooms, commonly known as and abbreviated as GWM, is a higher than average potency shroom. Originally a cross between the A-strain and Puerto Rican, but ultimately a result of accidental exposure to quaternary reactive ammonium siloxane.
This special strain is the only P. Cubensis strain known to have both albino and leucistic spores. The fruiting bodies of this magic mushroom are white like albino shrooms but it is in fact leucistic (partial loss of color pigmentation). The GWM is also known to have large fruits, slow to grow but prolific grower.
