Jack 47 Fast version is an F1 version of the original Jack 47. It was created by crossing an elite clone of the original photo-period strain with its own auto-flowering version. The resulting strain maintains its photo-period property but with a shorter period of florescence for those in a hurry.
This 75% sativa plant flowers one week earlier than the original "full-term" version. It is a very vigorous hybrid that is very adaptable to different cultivation techniques and will produce between 500 - 600gr/m2 in 7 - 8 weeks flowering. Outdoors growers can expect bumper crops for a mid-September harvest in the northern hemisphere. Despite its majority sativa genetic profile it nonetheless produces dense buds that are packed with trichomes exuding a large amount of resin. This strain is very easy to take cuttings from and they will root quickly
