Auto White Widow
Auto White Widow is a modern, auto-flowering variety derived from the integration of ruderalis genetics. This strain is designed for ease of cultivation, thriving in both indoor and outdoor environments with a relatively short flowering duration of 65 days. While it produces a low yield, its accessibility makes it a practical choice for growers seeking a streamlined production cycle. According to lore, its lineage is widely credited to the influential Dutch lines that revolutionized the industry in the 1990s.
The chemical profile of Auto White Widow is characterized by a complex terpene ensemble led by myrcene, followed by caryophyllene, limonene, pinene, and terpinolene. The secondary and tertiary concentrations include linalool, beta-pinene, humulene, nerolidol, and ocimene, with trace amounts of bisabolol, guaiol, camphene, caryophyllene-oxide, and p-cymene. This specific arrangement of compounds dictates the strain’s distinct sensory profile, presenting a nuanced aromatic structure that defines the user’s olfactory experience.
As a THC-dominant cultivar, Auto White Widow is primarily utilized for its relaxed, happy, and uplifted effects. These properties make it a frequent candidate for medicinal use cases, specifically regarding the management of stress, pain, and sleep-related concerns. The genetic footprint of this strain extends to several notable offspring, including Auto White Widow x Big Bud and Auto White Widow XXL, both of which retain aspects of the original development.

Russo 2011: naloxone-sensitive analgesia, potentiates barbiturate sleep; dominant sedating terpenoid; blocks hepatic carcinogenesis by aflatoxin.

spicy
●●○○
Russo 2011: only terpene that is a selective full CB2 agonist (100 nM); Gertsch et al. 2008: acts as dietary cannabinoid; unique anti-inflammatory and gastric cytoprotective properties.
Russo 2011: increases serotonin in prefrontal cortex + dopamine in hippocampus via 5-HT1A; Johns Hopkins 2024: significantly reduced anxiety vs THC alone.
Effects
Reported effects — derived from terpene chemistry and cannabinoid profile.
relaxed
eveningPrimary endpoint of myrcene+linalool sedating combinations; GABA modulation is the dominant mechanistic driver.
happy
anytimeuplifted
morningLimonene anxiolytic/antidepressant via serotonin elevation in prefrontal cortex (Russo 2011); mood improvement without full euphoria; key for balanced-1-1 profiles.
Genetic Profile
Autoflower
Photoperiod-independent. Flowers based on age, not light cycle. Compact and fast.
THC-Dominant
High THC, trace CBD. Psychoactive. Full CB1 agonism — euphoria, appetite, analgesia.
