About Northern Lights Auto

Northern Lights is a 81/19 indica testing at 19% THC with a linalool-dominant terpene profile. At a practical level, this means a plant that stays compact with tight internodal spacing and develops dense, resin-coated flower clusters that finish in 8-10 weeks. The Linalool/Myrcene combination shapes both the aromatic profile and the effect character — this is not a one-dimensional strain.

Growing Parameters

Flowering time: 8-10 weeks from flip. Indoor yield at 600+ PPFD: 300-400g/m². Outdoor in full sun with 5+ gallon containers: 500-700g/plant. Plant height indoors after training: Tall (4-5 ft). Feed EC targets: 1.0-1.4 in veg, 1.4-1.8 in peak flower. pH range: 6.0-6.5 in soil, 5.8-6.2 in coco. Linalool production peaks when day/night temperature differential exceeds 10°F in the final two weeks — growers who drop nighttime temps to 62-65°F during this window report stronger aromatic development.

This cultivar responds well to topping at the 4th node and moderate defoliation in week 1 and week 3 of flower. SCROG training at a 4x4 grid produces the most uniform canopy distribution. Rated intermediate difficulty.

What Users Report

Northern Lights at 19% THC produces relaxed, sleepy, happy sensations that users consistently describe as physically comforting without being immobilizing at moderate doses. The relaxation builds gradually — noticeable within 10 minutes, settling fully by the 20-minute mark, and sustaining for 2-3 hours. The Linalool/Myrcene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other indicas at similar THC levels.

Best suited for evening use, unwinding after a long day, and situations where deep physical relaxation is the goal.

Terpene Profile

Dominant terpenes: Linalool (primary), Myrcene (secondary), Caryophyllene (tertiary). This combination produces a nose that develops complexity through the cure — expect the primary linalool character to emerge first, with myrcene and caryophyllene notes adding layers over 3-4 weeks in jars.

Who Should Grow Northern Lights

This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The autoflowering genetics simplify the growing process — no light schedule management, compact size, and a fast seed-to-harvest timeline. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 8-10 weeks flowering period to their frost-free window.
