Lineage: Northern Lights #5 × Haze combines one of the most stable indica-rooted lines ever developed with the notoriously rangy Haze, and the result leans hard into the sativa side of that equation. Plants can push well past average canopy height, so growers working indoors should plan for aggressive training — topping or LST early keeps things manageable and helps channel energy into the dense, resin-coated colas this cross is known for. THC runs 18–24%, and a 10–14 week flower period is the trade-off for yields that routinely land in the 500–700g/m² range under good light.

The flavor profile is citrus-forward with a sweet, fruity finish that gets more pronounced as the cure matures. This is a moderate-difficulty grow that performs in both indoor and outdoor setups, but outdoor cultivators in warm climates with a long season will get the most out of it. Best suited to growers who have a few runs under their belt and enough vertical space to let the plant do what it naturally wants 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.
