Appearance

Chembap plants exhibit a classic indica-forward morphology, characterized by broad leaf blades, medium-wide petioles, and compact branching. The buds are typically dense, ranging from golf ball to cola size, with a high calyx-to-leaf ratio that simplifies trimming. Coloration can vary from vibrant lime green to darker olive hues, sometimes displaying anthocyanin blushing under cooler temperatures. The plants are heavily coated in trichomes, giving them a frosted appearance that intensifies by harvest.

Aroma & Flavor

The aroma of Chembap is dominated by a sharp, volatile chemical-fuel note, reminiscent of solvent or gasoline, layered with earthy and peppery undertones. Subtle citrus or tangy facets may also be present. The flavor profile closely mirrors the aroma, with initial notes of diesel and black pepper, followed by a subdued herbal sweetness and a lingering, slightly metallic or mineral finish characteristic of chem strains.

Effects

Chembap is reported to provide a body-forward effect, contributing to a sense of calm. While specific details on the onset and duration are not extensively detailed, the indica-leaning genetics suggest a relaxing experience.

Terpenes & Cannabinoids

Chembap typically tests between 18-24% THC, with CBD levels below 1%. The terpene profile is often associated with caryophyllene, myrcene, and limonene, contributing to its pungent, fuel-like aroma. Minor cannabinoids like CBG are also present in measurable amounts. Total cannabinoid content generally ranges from 20-27%.

Growing

As an autoflowering indica/ruderalis hybrid, Chembap is known for its rapid growth cycle, often completing from seed to harvest in 70-85 days, with approximately 75 days of flowering. Plants typically reach heights of 60-100 cm indoors. Its structure is durable and compact, making it suitable for smaller spaces and allowing for multiple harvest cycles per year. It thrives under 18/6 or 20/4 lighting schedules.

Origins & Lineage

Developed by Mephisto Genetics, Chembap is an autoflowering cultivar that marries indica-forward chem genetics with ruderalis. While specific parentage is proprietary, the strain is noted for carrying the distinct aromatic and resin characteristics of the chem lineage, combined with the compact structure and accelerated maturation of indica and ruderalis traits. It is sometimes cataloged internally by Mephisto Genetics as ILL #64.
