Appearance

This strain typically exhibits tall, expressive growth with narrow, serrated leaves, often displaying 9 to 13 leaflets on mature plants. Expect significant stretch during flowering, with elongated, spear-shaped colas. Foxtailing is a common and desirable trait, indicative of its sativa heritage. The buds develop a frosty trichome coating, with pistils transitioning from cream to orange and copper hues as they mature.

The plant's open structure promotes better airflow, reducing susceptibility to mold compared to denser bud types. Support structures like trellises may be necessary as the flowers develop significant mass. Leaves tend to maintain a lighter green color, especially with careful nitrogen tapering during bloom.

Aroma & Flavor

The aroma is a complex layering of incense, citrus rind, and dry wood, often described as reminiscent of church incense with notes of cedar and sandalwood. Secondary aromas include lemon peel, lime zest, and a hint of pine, adding brightness. As the flowers cure, deeper spicy and herbal notes, such as peppercorn and bay leaf, may emerge. Some phenotypes can exhibit a sharp, metallic, or ozone-like edge.

When ground, the aroma is amplified, presenting as lively and effervescent, distinctly different from modern dessert or fuel-dominated profiles. The flavor follows the aroma, offering a clean yet penetrating profile with prominent citrus and incense notes, complemented by woody and peppery undertones.

Effects

Kees' Old School Haze is known for delivering a soaring, electric cerebral effect that is characteristic of classic sativa genetics. This uplifting experience is often described as clear and long-lasting, appealing to experienced consumers seeking complexity. The strain is designed to provide a stimulating mental uplift rather than heavy sedation.

Terpenes & Cannabinoids

This strain typically tests between 15-25% THC and has less than 1% CBD. The terpene profile is noted for being terpinolene-forward, with contributions from limonene and caryophyllene. These terpenes contribute to the strain's characteristic incense, citrus, and woody aroma and flavor profile, with secondary spicy and herbal notes also present.

Growing

Cultivating Kees' Old School Haze requires patience due to its longer flowering cycle, a deliberate preservation of classic Haze traits. Growers should anticipate significant vertical growth and stretch, necessitating training techniques for indoor environments. The plant's morphology favors an airy canopy, which aids in preventing bud rot, but support may be needed for developing colas.

Phenotype variation is common, with growers often observing 3 to 4 distinct expressions. Careful management of nutrients, particularly nitrogen tapering, is advised. The strain is considered a benchmark for understanding equatorial-influenced cannabis biology and rewards growers with skill in canopy management and environmental control.

Origins & Lineage

Kees' Old School Haze was curated by Super Sativa Seed Club (SSSC), a Dutch seed bank founded in the late 1980s. It is a revival of the original Haze genetics, with the name honoring SSSC's master breeder, Kees. The breeding philosophy focuses on stabilizing the historical character of late 1970s and early 1980s Haze, avoiding trendy crosses.

The genetic foundation is believed to be a composite of Colombian, Mexican, Thai, and South Indian sativa landraces, mirroring the canonical description of Original Haze. SSSC aimed to recreate the incense-heavy, citrus-woody architecture associated with the earliest Haze releases, prioritizing chemotype fidelity and historical significance.
