White Widow XXL Auto is a modern autoflowering variety derived from ruderalis genetics. Designed for accessibility and simplicity, this strain is considered easy to cultivate in both indoor and outdoor environments. Growers can expect a 73-day flowering cycle, which typically results in a low yield. This strain serves as an important genetic contributor in contemporary breeding, notably acting as a parent to Moby Dick XXL Autoflowering.

The complex organoleptic profile of White Widow XXL Auto is defined by a deep hierarchy of terpenes, led by myrcene, caryophyllene, and limonene. Secondary and tertiary contributions from pinene, terpinolene, and linalool round out the profile, followed by beta-pinene, humulene, nerolidol, and ocimene. The presence of bisabolol, guaiol, camphene, caryophyllene-oxide, and p-cymene provides additional aromatic nuance to the overall experience.

As a THC-dominant variety, White Widow XXL Auto is characterized by effects that are consistently relaxed, happy, and uplifted. These properties make the strain a functional option for users seeking relief from stress and pain, or support for sleep. Its status as a potent, modern autoflower secures its reputation as a reliable building block for further genetic development.
