Just like the rest of our experimental F1 varieties, Jack 47 Fast Version saved most of its original traits while finishing two weeks earlier than classic photoperiodic strains. We made it possible by crossing initial varieties and Ruderalis. The secret is that the gene responsible for automatic flowering is recessive. So, in order to achieve 100% autoflowering plants you have to go through several generations of breeding. And the very first generation hybrids don’t receive autoflowering properties, but instead they get the ability to bloom faster. Since this is just the first generation, F1 plants don’t get many Ruderalis properties and therefore, their potency and yields haven’t been touched at all.

Yields are plentiful, approximately 500-600 grams per square meter indoors, roughly the same amount outdoors (per plant).

Jack 47 is a smelly one for sure. Aroma is mostly skunky, there are some earthy and pine hues.



Jack 47 Fast Version is a Sativa-dominant hybrid, which leads to a very vivid and stimulating “high” effect on the brain. You’d better make certain that you don’t smoke too much, especially if you just started smoking weed. Extreme doses can cause unpleasant paranoia-like effects for some people, most notably newbies. Good choice for smoking during the day, probably not something that you want to use before going to bed.
