Jack Herer is a name that needs no introduction among cannabis enthusiasts, and the strain named after him carries the same legendary status. With Royal Jack Auto, Royal Queen Seeds puts that iconic profile into an easy-to-grow autoflower by crossing Jack Herer with ruderalis.
The original Jack Herer draws on Haze, Northern Lights and Skunk, a blend known for an uplifting, sativa-leaning high with a stony undertone. Royal Jack Auto keeps that character in a 40% sativa, 30% indica and 30% ruderalis package, and RQS presents it as a continued tribute to the man known as the Emperor of Hemp.
In many ways, this is a mini version of the original. Plants grow to 1 to 3 feet (30–91 cm) indoors and 2 to 3 feet (61–91 cm) outdoors, ideal for small tents and discreet gardens. Expect 12 to 14 oz/m² (340–397 g/m²) indoors and 2 to 4 oz/plant (57–113 g/plant) per plant outdoors.
Flowering takes 50 to 55 days (7 to 8 weeks), with harvest arriving 75 to 85 days (11 to 12 weeks) after sprouting. In late bloom, a fresh, peppery, pine-forest scent fills the room.
Flavor, Aroma, and Effects of Royal Jack Auto
The smoke is fresh and smooth, led by cracked pepper and pine needles with a spicy, herbal Haze layer and an earthy base. It is a crisp, outdoorsy profile that feels like a walk through an evergreen forest.
With THC up to 16%, Royal Jack Auto delivers a creative, energizing high that clears the head and builds motivation. The Northern Lights and Skunk influences add a relaxed, stony body feel that keeps the energy from becoming jittery. It feels like hitting your stride on a long bike ride with the wind at your back.
This is a strain for active days: brainstorming, making music, tackling projects or exploring the outdoors.
Growing Royal Jack Auto Seeds
Sow straight into the final pot and keep lights on 18/6 or 20/4 for the whole cycle. No light change is needed, since the plant starts blooming on its own. Thanks to its small stature, Royal Jack Auto slots easily into closets, grow boxes and balconies.
Light LST in the early weeks evens out the canopy and improves bud development on side branches. Outdoors, plant after the last frost, and in long summers you can run two or more cycles in one season. Moderate feeding and good airflow keep the plant healthy through bloom.
