Auto Onyx

Cannabis Strain by Seedsman

Introduction
## Overview Auto Onyx is a ruderalis/indica/sativa autoflower from Seedsman, named for its dark phenotypic expression — deep green to near-black foliage and purple-tinged buds under cooler conditions. The variety completes its life cycle in approximately 67 days from germination. Seedsman's breeding programme has emphasised both visual appeal and a well-rounded effect profile in this cultivar.

Lineage
## Aroma & Flavour The aroma of Auto Onyx is dark and complex — earthy and hashy with notes of dark fruit (think blackberry and grape), woody undertones, and a subtle spice. The visual darkness of the plant seems to extend into its olfactory character. On the palate, the earthy and dark fruit notes carry through, with a smooth, resinous finish that is characteristic of indica-leaning genetics.

Terpenes
## Effects & Experience Auto Onyx produces a deeply relaxing and sedative experience, with the indica genetics firmly in control of the effect trajectory. The onset is gradual and pleasant, with a quiet mental calm preceding the physical relaxation. This variety is best suited to evening or night-time use, as the sedative quality becomes increasingly pronounced over time.

Growth
## Growing The dark phenotypic colouring that gives Auto Onyx its name is most expressed when overnight temperatures drop by 10°C or more during late flowering — a phenomenon driven by anthocyanin pigment activation. Plants are of standard autoflowering compact stature. The 67-day cycle is efficient, and the visual appeal of finished buds makes this variety distinctive among autoflowering cultivars.

Effects
## Medical Use The sedative and deeply relaxing effects of Auto Onyx may support individuals dealing with insomnia, chronic pain, or high levels of stress. The dark fruit terpene profile is associated with relaxing indica varieties. Therapeutic application should be discussed with a medical professional.

Documentation
## Terpenes Myrcene dominates, providing the earthy base and sedative effect contribution. Anthocyanin-associated pigmentation is complemented by caryophyllene spice notes. Linalool adds a gentle floral element that softens the overall profile.
