The shortest version: Royal Queen Seeds's take on indica genetics, 10-14% THC, 6-8 weeks total flowering, easy grow.

Royal Queen Seeds lists this at $19.00 — below the median of $25.98 across 53 listings. Pack options: 3-seed at $19.00, 5-seed at $28.92, plus larger sizes.

Lineage: Northern Light × Ruderalis — and that cross does exactly what you'd hope. The ruderalis clock kicks in fast, wrapping up flower in as little as six weeks from seed without any light-schedule fiddling. What you're left with is a compact indica that pulls 500–550g/m² under good conditions and tests in the 10–14% THC range — modest enough that you stay functional, not floored. The nose leans citrus and fruit with a grounding earthiness underneath, nothing sharp or chemical. Because difficulty is genuinely low and it runs well indoors or out, this is one of the few strains where a first-time grower can follow basic care and still hit respectable numbers.

Best suited for newer growers who want a forgiving, fast-finishing plant, or anyone who needs a lighter-hitting indica they can actually use during the day.

Genetics & Lineage

Northern Light Auto traces its genetics to Northern Light x Ruderalis. This indica-dominant autoflower seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Royal Queen Seeds, 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 14%, this provides a mild, approachable experience great for beginners or those seeking gentle relief.

THC Level & Potency

Northern Light Auto delivers THC levels of 10-14%, placing it in the milder range, making it approachable for newer users or those seeking functional effects. 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 Northern Light Auto

Northern Light Auto is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 6-8 weeks total with yields of 500-550g/m². Plants typically reach 80-120cm 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 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Northern Light Auto features a fruity, citrus, earthy, pine terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. 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 Light Auto 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 Northern Light Auto?

This strain is ideal for beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you're looking for evening relaxation and deep stress relief, this is your strain.
