An extinct type of cannabis that was found in Mantanuska Valley, Alaska. farmers grew this strain during summer which had almost 24 hours of sunlight and left out for one frost for the THC potency to reach maximum potential. can appear to be green, purple, and even white, and in rare cases, blue. The Mantanuska Thunderfuck is extremely potent and is a legendary strain and is now suceeded by the Mantanuska Tundra.
Matanuska Thunderfuck is extinct but you can grab some Matanuska Tundra which it is a little less potent.
