The shortest version: Sensi Seeds's take on sativa genetics, 18-24% THC, 10-14 weeks flowering, moderate grow.

Lineage: Northern Lights #5 × Haze is the cross that put Sensi Seeds on the map, and the plant still earns its reputation on numbers alone — 18–24% THC and documented yields in the 500–700 g/m² range when canopy management is dialled in. The sativa dominance shows up fast: these plants stretch hard, so growers running indoor tents under 2.4 m should top early or commit to aggressive LST before the flip. Flowering runs 10–14 weeks, which is a real commitment for a Canadian outdoor season, making a greenhouse the smarter call in most provinces north of the 49th parallel.

The smell profile leans citrus and sweet fruit with a clean finish — nothing muddy or one-note. Difficulty sits at moderate, mostly because of the height and the longer flower window rather than any finicky feeding requirements. Best suited to growers who have a previous harvest or two behind them and enough vertical space to let this one do what it was bred to do.

Indoor Growing: Expect a flowering time of 10-14 weeks with yields of 500-700g/m². Plants typically reach 100-180cm 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 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Northern Lights #5 X Haze features a fruity, citrus, sweet, earthy 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 Lights #5 X Haze 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.
