Quick read: 20-25% THC, 100-180cm mature height, 9-11 weeks bloom. Genetics: Great White Shark Feminized (Nirvana Seeds). Difficulty: moderate.

Smell-first impressions here lean citrus-forward — bright rind on the inhale, then a wave of old-school skunk that settles at the back. That combination has made Great White Shark Feminized a repeat order for growers chasing the kind of nose that Amsterdam seed houses built their reputation on through the 1990s. THC tests consistently land in the 20–25% range, which sits firmly in the upper tier for a feminized sativa without requiring a controlled-environment setup — this one runs fine indoors or out.

Flowering wraps up between 9 and 11 weeks, and indoor canopies typically finish at 400–500 g/m² with reasonable feeding and light discipline. Difficulty rates moderate, so first-season growers can manage it, but she rewards anyone who takes the time to dial in their VPD through stretch. A solid pick for Canadian outdoor growers in BC or Ontario who want a proven sativa-leaning variety that finishes before the first hard frost window closes in October.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day.

With THC levels reaching 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Great White Shark delivers THC levels of 20-25%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes, starting as a cerebral buzz that gradually expands.

Growing Great White Shark

Great White Shark is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 9-11 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. 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 dense flower formations.

Flavor, Aroma & Terpene Profile

Great White Shark features a fruity, citrus, skunky, 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, Great White Shark 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. Consult a healthcare professional before using cannabis for medical purposes.
