Onyx
Also known as: Black Onyx
Onyx Strain Overview
Onyx is a relatively rare indica-dominant cannabis strain known for its deep purple to almost black coloration and potent sedative effects. The strain's exact origins are somewhat obscure, with most sources suggesting it was developed by crossing two classic indica varieties, though the specific parentage remains debated among cannabis historians. What distinguishes Onyx is its striking visual appearance, with buds that often display such intense purple pigmentation that they appear nearly black in certain lighting conditions, particularly when grown in cooler temperatures that enhance anthocyanin production.
The strain gained attention in the early 2000s within certain cannabis communities for its unique aesthetics and powerful physical effects. Onyx typically produces dense, resinous buds with a coating of trichomes that contrast dramatically against the dark foliage. The strain's rarity has contributed to its somewhat legendary status among connoisseurs, though it has never achieved widespread commercial distribution. Its limited availability means that much of the information about Onyx comes from grower reports and enthusiast communities rather than formal laboratory testing or large-scale cultivation data.
Onyx is characterized by a growth pattern typical of indica varieties, with a compact, bushy structure and broad leaves. The strain's visual appeal is its most notable feature, with the dark coloration developing most prominently during the final weeks of flowering when exposed to cooler nighttime temperatures. While not as genetically stable as more commercially established strains, Onyx has maintained a dedicated following among growers and users who appreciate its unique appearance and deeply relaxing effects.

Onyx Strain Growing Information
Onyx is considered a moderately difficult strain to cultivate, best suited for experienced growers. The strain has a flowering time of approximately 8-9 weeks when grown indoors, with outdoor harvest typically occurring in late September to early October in northern hemisphere climates. Onyx prefers a controlled indoor environment where temperature can be carefully managed, though it can be grown outdoors in Mediterranean or similar climates. The plant remains relatively short, usually reaching 90-120 cm indoors and up to 150 cm outdoors. Yield is moderate, with indoor growers reporting approximately 400-500 grams per square meter under optimal conditions. Special considerations include the need for temperature manipulation during the final flowering phase to enhance the characteristic purple/black coloration - exposing plants to nighttime temperatures of 10-15°C (50-59°F) during the last 2-3 weeks can intensify the dark pigmentation. The strain is somewhat sensitive to nutrient levels and requires careful monitoring to avoid nutrient burn.
