yes the Thai Dragon is very hot, but INDIAN PC-1 is about the hottest c. annum species i have come across yet
i just harvested a bunch off my Buddie's field last week and let me tell you there no joke!!
the Indian police used to use the extract from them for there teargas grenades until they started using the BHUT JOLOKIA
they found that the Bhut gave more extract and much more potently
Personally I was very dissapointed with the heat and flavor of the pc-1 but I guess it depends on your seeds source. I've seen results of 6208 SHU(ecoseeds) and 81984(Reimers) but never buy from Reimers
