For the autoflowering variant, the genetics were brought into an autoflower format without changing the characteristic indica profile: same effect, same aroma, no light schedule. ## Northern Lights Automatic THC content With **20–22% THC**, Auto Northern Lights is one of the most potent autoflowering strains on the market. Most autoflowering strains sit at 15–18% THC — Auto Northern Lights clearly exceeds that average. The high **Northern Lights Automatic THC content** explains the intense, long-lasting indica effect that makes the strain so popular. ## Northern Lights Automatic effects The **Northern Lights Automatic effect** is typically body-focused and deeply sedating — a classic indica experience: - **Deep muscle relaxation** — a narcotic body effect, tension releases quickly - **Stress relief** — ideal in the evening after a long day - **Sleep support** — a sedating effect at higher doses - **Calm serenity** — a relaxed mood lift without cerebral over-activation The effect sets in quickly and is pronouncedly physical — ideal for the evening and for recovery. ## Aroma and flavour The aroma profile of **Auto Northern Lights** is the unmistakable NL profile: earthy, sweet, with clear pine-resin notes and a slightly spicy finish. The smell during flowering stays discreet — one of the hallmarks of Northern Lights genetics and a clear advantage for indoor projects and balcony growing. ## Auto Northern Lights terpene profile The terpene profile reflects the classic indica origin: earthy, calming, warm. The three dominant terpenes: Terpene | Typical impressions | Contribution to the profile **Myrcene** | Earthy, musky, sweet | Mainly responsible for the sedating, relaxing effect — the "couch-lock" terpene **Caryophyllene** | Spicy, peppery, warm | Adds spicy depth and balances the earthy base profile **Linalool** | Floral, slightly sweet | Supports the strain's anxiety-relieving and sleep-promoting effect Together they form a classic **indica terpene profile**: calming, warm and earthy — ideal for anyone who values Northern Lights not just for the effect but for the authentic aroma. ## Northern Lights Automatic flowering time & harvest The **flowering time of Auto Northern Lights** is **70 days from germination** — as little as 63 days under LED.
