Appearance

Koma produces dense, compact flowers that can resemble golf balls or elongated spears. Buds are typically olive to forest green, sometimes showing deeper hues with cooler temperatures, and feature prominent, swollen calyxes. The pistils mature from pale tangerine to a deeper amber. A notable characteristic is the thick coating of trichomes, giving the buds a frosted appearance and a sticky texture.

The plant structure is classic indica, with short internodal spacing and broad leaves. It exhibits strong lateral branching capable of supporting heavy colas, especially when grown with support like SCROG. Growers should manage humidity within dense canopies to prevent issues.

Aroma & Flavor

The aroma of Koma is a complex blend of earth, tropical fruit, and warm spice. Initial scents are sweet and musky, reminiscent of mango or papaya, grounded by notes of soil and cedar. Upon breaking apart the buds, peppery undertones emerge, complemented by subtle citrus hints.

Flavors often mirror the aroma, presenting a profile that includes citrus, tropical fruit like mango, and floral or lavender notes, underpinned by herbal and peppery spice. This complexity is attributed to the interplay of various terpenes.

Effects

True to its name, Koma is known for inducing a heavy, tranquil body experience, promoting deep relaxation and sedation. Its effects are often described as calming and are well-suited for evening use or unwinding after a long day.

The strain is associated with a pronounced couch-lock effect, making it a popular choice for those seeking significant physical relaxation. While potent, reports suggest it offers a layered experience rather than a simple knockout.

Terpenes & Cannabinoids

Koma is characterized by a chemotype typically leaning towards indica-dominant genetics. THC levels commonly range from 18-24% under optimal conditions, with CBD content below 1%. Total cannabinoid percentages can exceed 20%.

The terpene profile is often described as myrcene- and caryophyllene-forward, with limonene and humulene present as secondary compounds. This combination contributes to its relaxing, peppery-sweet aroma with a hint of citrus lift.

Growing

Koma is an indica-leaning cultivar that typically exhibits a compact morphology, reaching heights of 80-140 cm indoors without aggressive training. It features short internodal spacing and sturdy lateral branching, making it suitable for techniques like SCROG. The flowering time is generally 8-10 weeks.

The plant is noted for its hardiness and stability, performing well in controlled indoor environments and sheltered outdoor gardens in warm-temperate to subtropical climates. It responds well to low-stress training and topping. Growers should ensure adequate airflow and humidity management within dense canopies.

Origins & Lineage

Koma was developed by Jamaica Seeds, a breeder recognized for integrating Caribbean influences into modern cannabis genetics. While the exact parentage is not publicly disclosed, its indica-leaning phenotype suggests a foundation from classic broadleaf indica lines, potentially including Afghani, Kush, or Northern Lights types.

The breeding likely aimed to combine the stability and compact stature of indicas with tropical ancestry to enhance resin aroma and heat tolerance. This approach results in a cultivar that balances potent, sedative effects with aromatic complexity and reliable garden performance.
