Royal Jack Automatic Bulk Seeds: A Fast and Reliable Legend

Inspired by the legendary activist Jack Herer, our Royal Jack Automatic cannabis seeds have become an auto grower favourite here at RQS, and are now available to purchase in bulk. A combination of the Jack Herer cannabis strain and ruderalis genetics, Royal Jack Automatic features everything loved in its parent, all presented in an easy to manage auto package.


Royal Jack Automatic maintains the much-celebrated effects of its photo-period namesake. The taste and aroma are herbal, with distinct spicy and peppery notes. The high she produces is the same potent, uplifting and motivating high Jack Herer is known for. However, it's not a purely cerebral experience. Thanks to other strains in Royal Jack Automatic's heritage, she also induces a calming, relaxed body buzz. It's quite the combo! In addition, Royal Jack Automatic has a THC content of 16% that combines with a medium level of CBD. It makes the high easy to control, but potent enough to push for those looking for a bit of a kick.


Many have described Royal Jack Automatic as a mini-version of Jack Herer, and these people are not far from the truth! The main difference is that thanks to the auto genetics, Royal Jack Automatic can be grown multiple times per season, just about anywhere.

Indoors, this squat plant will grow up to 80cm, going from seed to harvest in 9–10 weeks. Despite this small size, she is able to produce up to 400g/m²—not bad for a small auto!

Outdoors, Royal Jack Automatic will not get much taller than it does indoors, but she is more likely to reach that 80cm mark. She will still go from seed to harvest in 9–10 weeks outdoors, yielding up to 120g/plant in ideal conditions.

If you are looking for a bit of cannabis history that honours a legend of the cannabis community, and you want it in bulk, then Royal Jack Automatic cannabis seeds should be a strong contender.
