Jack Herer Auto: Experience the autoflowering version of Jack Herer

Jack Herer has won so many awards, Greenhouse Seeds has lost count. This may be the reason why they decided to create an autoflowering variety of Jack Herer - an impeccable strain named after the cannabis activist and connoisseur, Jack Herer. May his soul rest in peace.

The uplifting highs of this legendary strain will get your blood pumping. Whether at a pro-legalization rally, at a concert or just goofing around at home, Jack Herer Auto does the trick, just as well as its photoperiod counterpart.

The lifespan of this beauty lasts for 9 weeks, from seed to harvest. Greenhouse Seeds did a fantastic job selecting and stabilizing the correct genetics to produce such a short lifespan, without losing the inherent Jack Herer qualities.

THC levels will be slightly lower than with the photoperiod version, the yields as well, although the short growth cycle and quality compensate for that. On the other hand, the yields are quite alright for an autoflowering variety. Indoor growers can expect 700g/m² of buds, while outdoors one can expect about 100g/plant.

If you wish to grow Jack Herer, but the limited space of your grow room prohibits you from doing so, just plant Jack Herer Auto. It’s a short plant, perfect for small stealthy operations.
