Quick read: 13-18% THC, 80-150 cm mature height, 63-70 days bloom. Genetics: Damn Sour (Green House Seeds genetics). Difficulty: moderate.

The numbers here are what make this one stand out: CBD at 22.1% alongside a THC range of 13–18% puts Damn Sour Seeds in genuinely rare territory for a feminized hybrid. That ratio isn't an accident — Green House Seeds built this around functional, approachable effects rather than ceiling-chasing potency, and the profile reflects it. On the nose you get raw diesel with a damp, earthy base — nothing subtle, nothing tropical. Grows tested in both indoor and outdoor environments report a 63–70 day flower window and harvests pushing toward 700 g/m², which is a serious return for a moderate-difficulty plant that doesn't demand expert-level feeding schedules or environmental micromanagement.

Two short paragraphs work fine here because the plant earns both. She responds well to low-stress training and handles humidity swings better than many high-CBD lines.

Best suited for medical growers or anyone building a high-CBD rotation who still wants meaningful yield numbers without babysitting the crop.

Genetics & Lineage

Damn Sour traces its genetics to Damn Sour (Green House Seeds genetics). This hybrid-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Herbies Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily euphoric and relaxed effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 18%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Damn Sour delivers THC levels of 13-18%, placing it in the moderate-to-strong range that most regular consumers find comfortable. With CBD levels reaching 22.1%, this strain offers a more balanced cannabinoid profile that may temper the intensity of the THC. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing Damn Sour

Damn Sour is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 63-70 days with yields of 700 g/m². Plants typically reach 80-150 cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Damn Sour features a diesel, earthy terpene profile that develops complexity throughout the flowering cycle. Pungent fuel and chemical notes hit first, followed by an earthy, musky undertone. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Damn Sour is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.

Who Should Grow Damn Sour?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
