Undertow is a modern hybrid cannabis strain derived from the parent cultivar Wet Betty. As a specific product of recent selective breeding, the variety has established itself through a consistent and reliable genetic profile, leading to its utilization in the development of several notable offspring, including Flap Jackz, Moonshadow, Rainbow Showers, and Suga' Shine.

The aromatic and flavor profile of Undertow is defined by a complex arrangement of terpenes, led by a dominant presence of caryophyllene followed by limonene, myrcene, and humulene. This structural chemistry is further nuanced by the presence of linalool, beta-pinene, and pinene, with trace contributions from bisabolol, camphene, terpinolene, nerolidol, geraniol, terpinene, and ocimene. This terpene array creates a distinct sensory experience characterized by the chemical interactions of its diverse volatile compounds.

This THC-dominant hybrid is reported by consumers to produce effects that are primarily relaxed, happy, and uplifted. These characteristics make it a functional choice for those seeking relief from stress and pain, as well as assistance with sleep. Growers can expect a moderate cultivation difficulty in both indoor and outdoor environments, with the plant reaching maturity after a 63-day flowering period and providing a high yield at harvest.
