About Chemdog 91 S1

Chemdog 91 S1 is CSI Humboldt's selfed seed preservation of the legendary Chemdog '91 clone, one of the most historically significant cannabis cultivars ever discovered. The original Chemdog '91 traces back to 1991, when a grower known as "Chemdog" cracked seeds from an exceptional bag of cannabis purchased at a Grateful Dead concert. By selfing this iconic clone, CSI Humboldt has made these elite genetics available in seed form. The strain's genetic influence is immense, having given rise to legendary varieties such as Sour Diesel and OG Kush. As a balanced hybrid with THC levels ranging from 19% to 27%, Chemdog 91 S1 delivers a potent, multi-layered experience that begins with an uplifting, euphoric head rush accompanied by surges of creative energy, mental clarity, and social motivation. This cerebral stimulation builds into a state of focused well-being, making it an excellent choice for daytime activities, artistic pursuits, and social gatherings. The flavor profile is unmistakable and boldly pungent, defined by sharp diesel fuel notes layered over an earthy, chemical backbone that gives the strain its iconic name. Undertones of lemony citrus and pine provide bright counterpoints to the heavier fuel-forward flavors, while a persistent skunky muskiness rounds out the complex palate. Medicinally, Chemdog 91 S1 is widely valued for its effectiveness in managing chronic stress, depression, pain, nausea, appetite loss, and insomnia. Growers can expect sturdy, well-branched plants with dense, resin-coated buds that flower in approximately 8 to 10 weeks.
