I like Manatuska Thunder Fuck ,grown in alaska from clones only pretty much, as no seed company has been able to produce a reliable F1 seed that does not revert back to one of the hybrids parent strains. But MTF is hard to get outside of Alaska ,but I have gotten some from Alaska and it was about the strongest weed I have smoked. It was tested at 32% avg. THC, higher than any other strain that I know of anyway, but since the growers all live in the same area and grow MTF from clones , several I know are from there and all grow the MTF from clones, it is not a common strain outside of the area unless you know someone who is from there or you knows a grower there. however they have developed MTF#2 which I have never smoked ,but is supposed to be a stable hybrid to grow from a seed instead of clones like MTF.
I still have not seen any MTF#2 in any seed companys inventory, maybe the people that grow MTF and MTF#2 are keeping it for themselves in a way. I have seen a seed company offer Yukon gold and other Alaskan named strains, but not MTF#2. Anyway MTF would be a great strain for anyone because it's tested at 32% avgerage THC!!! That's higher than any strain I know of, but with growers coming out with new hybrids all the time, It is only a matter of time before some other strain is developed that is in the 30%+ THC range, if there is not one already..
