About Jack 47 Fast
This Jack 47 Fast pairs a selected autoflowering line of Jack 47 with an elite clone of the original photoperiod Jack 47, folding the speed of one parent into the character of the other. THC sits on the milder end at 12 to 15 percent, and true to the Fast name, flowering wraps up in just seven to nine weeks. Listed under Clearance, it reads as a more accessible route into Jack 47 genetics without the longer photoperiod commitment the original line typically demands. Combining an auto and a photo version of the same strain is an unusual breeding choice, aimed squarely at growers who want the classic Jack 47 identity but on a faster, more forgiving timeline than the elite clone alone would allow.
