Spec sheet first — strain: indica, seed type: feminized, THC: 23-28%, yield band: medium, environment: indoor or outdoor.

Lineage: OGKB × Face Off OG — two heavy OG-family cuts crossed to push THC into the 23–28% range while keeping the growth pattern manageable for intermediate growers. Do-Si-Dos runs 8–9 weeks to finish and can pull 400–500 g/m² indoors under dialled lighting, which is a respectable number for a plant this resinous. The aroma leans sweet and earthy throughout flower, with the smell intensifying noticeably in the final two weeks before harvest. She handles both indoor tents and outdoor runs through the warmer parts of a Canadian season, though outdoor growers in shorter-summer regions should plan their transplant timing carefully to hit that 8–9 week window before temperatures drop. Canopy management matters here — she stacks dense nodes and benefits from LST or a light defoliation pass at week three.

Best suited to growers who have a few harvests under their belt and want a high-THC indica that rewards attentive feeding and a proper dry-and-cure.

Genetics & Lineage

Do-Si-Dos traces its genetics to OGKB x Face Off OG. This indica-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 North Atlantic Seed Co., each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and sleepy 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 28%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Do-Si-Dos delivers THC levels of 23-28%, 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 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Do-Si-Dos

Do-Si-Dos 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 8-9 weeks with yields of 400-500 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 40-50% 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

Do-Si-Dos features a sweet, earthy terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. 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, Do-Si-Dos 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.
