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 - 600 gr/m Outdoors in 7 - 8 weeks flowering. CBD 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, usually in 7 days or so. Both the flavour and perfume of Jack 47 Fast are fresh and sweet with notes of incense and lemon/citrus. THC production is very high at between 18% - 24% with 1.4% . The effect is rather typically sativa with an uplifting and potent high.
