Quick read: 30-35% THC, 80-150 cm mature height, 50-55 days bloom. Genetics: Northern Lights 10 of 10 (Seedkeepers genetics). Difficulty: moderate.

The lab panel on this one raises eyebrows: THC sitting in the 30–35% range alongside a reported 35% CBD puts it in territory most cultivars never approach. That cannabinoid profile comes from Seedkeepers' own Northern Lights 10 of 10 line, a project focused on pushing the classic NL genetics toward higher potency without losing the strain's signature earthy pine character.

Indoors or out, expect dense returns in the 500–600 g/m² range after a relatively short 50–55 day flower period. Difficulty lands at moderate — she's not fussy, but she rewards growers who keep feeding dialled in during the stretch. Earthy, resinous pine is the dominant note from first sniff through to cure. Because the cannabinoid numbers here are unusually high across both THC and CBD, this is worth considering for growers building a medical-leaning personal harvest under their Health Canada personal cultivation allowance.

Genetics & Lineage

Northern Lights 10 of 10 traces its genetics to Northern Lights 10 of 10 (Seedkeepers 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 35%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Northern Lights 10 of 10 delivers THC levels of 30-35%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. With CBD levels reaching 35%, 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 Northern Lights 10 of 10

Northern Lights 10 of 10 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 50-55 days with yields of 500-600 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

Northern Lights 10 of 10 features a earthy, pine terpene profile that develops complexity throughout the flowering cycle. Sharp forest and resin notes create a fresh, invigorating flavor with earthy depth. 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, Northern Lights 10 of 10 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.
