Thor’s Hammer XXL F4 is a modern, autoflowering variety developed through the continued refinement of its direct ancestor, Thor’s Hammer AutoFlowering. This F4 generation exhibits a truncated lifecycle, reaching maturity in 70 days of flowering. Due to its accessible cultivation requirements and reliable growth traits, this strain is classified as easy to grow and is suitable for both indoor and outdoor environments, though producers should anticipate a low yield.

The chemical profile of this strain is defined by a complex, diverse array of terpenes, led by a dominant presence of caryophyllene followed by myrcene and limonene. This aromatic foundation is rounded out by pinene, humulene, and ocimene, with trace contributions of nerolidol, linalool, beta-pinene, guaiol, p-cymene, bisabolol, eucalyptol, camphene, and caryophyllene-oxide. This specific sequence of volatile compounds creates a distinct sensory profile, characterized by the sharp, spicy notes of caryophyllene tempered by the earthy undertones of myrcene and the bright, citrus-forward qualities of limonene.

As a THC-dominant cultivar, Thor’s Hammer XXL F4 induces effects primarily categorized as relaxed, happy, and uplifted. These characteristics make it a functional choice for those seeking relief from stress and pain, as well as those utilizing the strain to support sleep. The genetic influence of this F4 variation has proven to be a versatile building block for breeders, serving as a parent in the development of Purple Dodgers x Thor’s Hammer F4, Tommy Chong’s Kong x Thor’s Hammer F4, and Tropicanna Hammer.
