Northern Light 5 X Haze Feminized Seeds by Sensi Seeds – Award-Winning Sativa-Dominant Hybrid

Northern Light 5 X Haze feminized seeds by Sensi Seeds offer a legendary sativa-dominant hybrid that delivers euphoric highs, towering growth, and XXL yields—perfect for growers who want power, flavor, and award-winning genetics in one unstoppable strain.

Ever feel like your current strain just doesn’t lift you high enough or lacks that long-lasting spark? You plant, wait, and hope—but end up with average buds and a short-lived buzz that fades too fast.

That frustration of investing weeks into a grow only to get mediocre results? The disappointment when the high doesn’t match the hype? It kills the joy of cultivation and makes you question every seed choice.

Meet Northern Light 5 X Haze feminized—your solution to weak yields and underwhelming effects. With genetics rooted in one of the most celebrated crosses in cannabis history, this strain delivers towering plants up to 1.70 m (5.58 ft) indoors and massive harvests of up to 450 g/m² (1.6 oz/ft²). Expect a spicy-sweet aroma that evolves into a rich, haze-kissed smoke, and a high that starts euphoric and social, then melts into deep, lasting relaxation. Thanks to its stable genetics and strong mold resistance, it’s easier to grow than you’d expect—especially when you follow proven techniques like lollipopping and SCROG, which are perfectly suited to its branching structure.

Massive Yields Without the Wait

This isn’t just another tall sativa—it’s a yield machine. Northern Light 5 X Haze pushes past typical limits, producing up to 450 g/m² (1.6 oz/ft²) indoors and over 800 g (28.22 oz) per plant outdoors in warm climates. Its long flowering period is rewarded with dense, resin-coated colas that practically beg for a trim. The plant’s vigorous growth and strong branching mean it fills space fast, making it ideal for SCROG setups that maximize light exposure and bud development. Whether you're growing in soil or coco, this strain responds well to training and rewards attention with quality and quantity.

How to Grow Northern Light 5 X Haze for Maximum Results

Get the most out of your grow with these expert-backed steps tailored to this strain’s sativa vigor and flowering needs.

1. Start seeds in a moist, well-aerated medium at 22–25 °C and 60–70% RH.
2. Use 11–20 L pots depending on space; soil or coco with good drainage works best.
3. Keep light cycles at 18/6 during veg to control stretch; switch to 12/12 to trigger flowering.
4. Apply lollipopping early to improve airflow and direct energy to top colas.
5. Support tall branches with stakes or a SCROG net to prevent breakage under bud weight.
6. Flush with pure water 7–10 days before harvest to improve flavor and smoothness.
7. Cure buds slowly at 18–21 °C and 58–62% RH for 2–4 weeks to enhance aroma and potency.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Northern Light 5 X Haze last summer in my outdoor setup in southern Spain, and it was a showstopper. One plant hit 2.8 m (9.19 ft) and produced over 900 g (31.75 oz) after curing. I used lollipopping early and a SCROG net to manage the height and spread. The high came on fast—euphoric and talkative—then mellowed into a deep, peaceful calm that lasted for hours. I’ve tried other Haze crosses, but this one has a cleaner finish and better resin production. My only tip? Don’t rush the harvest. Wait until at least 10% of trichomes turn amber for that perfect balance of energy and relaxation.
