Appearance

Auto Black Jh typically grows to a medium height, between 70-110 cm indoors and slightly taller outdoors. It develops a sturdy main cola with branching laterals and moderately broad leaflets that narrow as flowers develop. Calyxes can exhibit dark or lavender hues in cooler temperatures, and trichome coverage is notably heavy, giving buds a frosted appearance.

The buds are compact and conical, with a good calyx-to-leaf ratio that aids in trimming. Pistils mature from vibrant orange to a deeper amber. Properly dried and cured, the dense nugs are reported to have good bag appeal.

Aroma & Flavor

The aroma profile of Auto Black Jh is layered, often presenting bright top notes of pine, citrus peel, and sweet herbs, grounded by base notes of damp cedar, cocoa, and black pepper. As flowers mature, a candied lemon and anise scent can emerge. Subtle hints of spice and incense may also be detected.

Flavors mirror the aroma, with an inhale reminiscent of lemon zest, juniper, and pine. The exhale introduces a warm spice and cocoa-like dryness, sometimes with a faint licorice or anise undertone. A well-cured batch may leave a lingering herbal sweetness with peppery edges.

Effects

Auto Black Jh provides a versatile effect profile due to its hybrid genetics. When consumed in smaller amounts, it is often described as functional and uplifting, suitable for all-day use. At higher doses, the effects can lean towards a deeper, more relaxing experience often associated with indica-dominant strains, making it suitable for evening consumption.

Terpenes & Cannabinoids

This strain typically contains THC levels ranging from 15-25% and less than 1% CBD. The terpene profile is suggested to include Myrcene, Caryophyllene, Pinene, Humulene, and Terpinolene. These compounds contribute to the strain's complex aroma and flavor, as well as its reported effects.

Growing

As an autoflower, Auto Black Jh integrates ruderalis genetics for day-neutral flowering, allowing it to bloom regardless of light cycles. It is considered a practical choice for smaller spaces and offers rapid turnovers, with a seed-to-harvest time of approximately 11 to 13 weeks. Indoor yields are often reported between 400-550 grams per square meter, with outdoor yields ranging from 60-150 grams per plant.

Origins & Lineage

Auto Black Jh by Original Sensible Seeds is a hybrid with a stated genetic makeup of ruderalis, indica, and sativa. The 'JH' in its name is widely interpreted as a nod to the classic sativa-dominant strain Jack Herer, suggesting potential influence from its terpinolene-forward bouquet and clear-headed effects. The 'Black' component often points to indica genetics known for resin density and potentially darker pigmentation.
