Royal Jack Automatic Genetic Crossing
Royal Jack Automatic by Royal Queen Seeds is the non-photodependant version of the acclaimed Jack Herer strain. To create this strain, Jack Herer was crossed over various generations with ruderalis strains, which are responsible for giving the flower its automatic flowering characteristics. Thanks to the detailed selection of phenotypes during the hybrid process this strain grows buds that are extremely similar to the original strain on a much smaller plant but with more branches.
Royal Jack Automatic indoor cultivation
Indoors this plant grows nice and compact during the vegetative phase, focusing on making the trunk thicker and growing more branches. Once flowering begins it will begin to rapidly grow until it reaches around 70cm, where it will stop and continue focusing on producing flowers. With about nine plants per square meter you can get up to 500g after a max of 10 weeks from germination.
Royal Jack Automatic outdoor cultivation
Outdoors, this strain’s small size is perfect for those that want a nice discreet smell as it won’t grow anywhere above 70cm, meaning that they’ll be pretty easy to hide and camouflage. This strain is slightly sensible to sharp changes in temperature, so we recommend growing this strain in areas where the temperatures tend to be quite stable during the day and night. Thanks to its amazing branch system you can get yields of 70g-120g from one plant, which should be ready 9 to 10 weeks after germination.
Royal Jack Automatic Psychoactive Effects
The flavor of this strain is similar to Jack Herer original, with a slight aroma of pepper or incense which combines perfectly with its characteristically dense smoke. Its peculiar effect will improve anyone’s mood regardless of how they feel, making it perfect for any occasion – especially for having a laugh with your mates.
- Sativa/Indica: 60/40%
- Flowering: from 9 to 10 weeks after germination

Honestly, it's one of the best autoflowering strains I've tried in terms of yield-to-price. Nothing to worry about!, this one never fails. It's always given me good results, it's a safe bet.

Wanted to share something curious, on the first one I put to germinate and it's a twin, meaning two plants from one seed, you just have to separate them carefully and boom two little twins to grow hehehe. Thanks a lot to growbarato, greetings to everyone and happy smoking.
