North Atlantic Seed Co. runs this as a sativa feminized line — 21-26% THC lab range, diesel/citrus-dominant terps, 10-11 weeks from flip.

Lineage: Original Sour Diesel × an RQS in-house selection, this feminized sativa carries the fuel-and-citrus nose the original strain built its reputation on — sharpened slightly for consistency and yield. Lab results from this line regularly land between 21–26% THC, which puts it firmly in the upper range for sativa-dominant varieties without tipping into the unpredictable territory some high-THC cuts occupy. Indoors, expect 475–575 g/m² after a 10–11 week flower stretch — longer than most, so growers running tight seasonal windows in shorter Canadian summers should plan accordingly. The difficulty rating sits at moderate: she responds well to topping and low-stress training but punishes neglect during late flower when resin production peaks.

Works in both indoor and outdoor environments, though outdoor runs in BC or Ontario need a greenhouse or early-finish strategy given the flowering window. Best suited to growers who have a few runs behind them and want a reliable, high-yielding sativa that doesn't require chasing exotic inputs.

With THC levels reaching 26%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Sour Diesel RQS delivers THC levels of 21-26%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes, starting as a cerebral buzz that gradually expands.

Growing Sour Diesel RQS

Sour Diesel RQS 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 10-11 weeks with yields of 475-575 g/m². Plants typically reach 80-150 cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. 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 dense flower formations.

Flavor, Aroma & Terpene Profile

Sour Diesel RQS features a diesel, citrus 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, Sour Diesel RQS is commonly reported to help with depression, fatigue, lack of motivation, and ADHD symptoms. The uplifting, focusing effects make it popular among medical users seeking daytime functionality. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
