Royal Jack Automatic: Royal Queen Seeds' tribute to the great Jack Herer

Every cannabis lover has heard of Jack Herer - the person and the strain - and most of us stoners have a deep love for both of them. Jack Herer in its original form is one of the most well-known strains of all time, and still pleases connaisseurs all over the world. The automatic version created by Royal Queen Seeds gives you all the classic traits, and is named Royal Jack Automatic.

Royal Jack Automatic performs well in indoor and outdoor conditions alike. The plant doesn't get too big with a maximum height of only 80cm indoors and 100cm outdoors, which makes it ideal for grow operations where height is an issue. This strain yields 70-120g/plant outdoors and between 350-400g/m² under artificial light. Since it is an automatic version, it takes only 9-10 weeks after you have planted the seeds to finish its life cycle.

Royal Queens Seeds' Royal Jack Automatic delivers strong, sativa-dominant marijuana with around 16% THC and medium CBD content. The high is uplifting, quite typical for a sativa-dominant strain, but there is also the added relaxation caused by its indica heritage. The aroma is fresh, peppery and Haze-like, while the flavor is fresh and smooth with a hint of spice and herb.
