Genetics & Origin of Great White Shark
Great White Shark is a long-proven strain from Green House Seeds. The breeder lists it as a strongly Indica-dominated hybrid with 80% Indica and 20% Sativa; it does not state in the strain description which parent strains were crossed. According to the manufacturer, the strain won 1st place at the Bio High Times Cannabis Cup in 1997. Green House Seeds gives precise cannabinoid values: 14.94% THC, 0.18% CBD and 0.25% CBN. The plants grow compact, bushy and branched. The seeds are feminised and photoperiod – so flowering only begins after the light cycle is switched. The manufacturer describes the genetics as proven and the growing characteristics as robust. Another strain from Green House Seeds in our range is Super Silver Haze.
Who Is Great White Shark For?
Great White Shark is a high-yielding Indica for the evening. It suits:
- Growers who grow in a Sea of Green or ScrOG
- Yield-focused growers with a well-ventilated room
- Outdoor and greenhouse gardeners who can harvest in early October
- Lovers of spicy, earthy Indica aromas with a sweet note
- Consumers looking for a deeply relaxing body effect in the evening
If you are looking for a stimulating daytime strain or particularly high THC values, you are better served by other strains. You can find more Indica-leaning strains under Indica strains.
Growing Great White Shark: Indoor & Outdoor
Indoor Growing
Indoors, Great White Shark flowers for 9 weeks. Green House Seeds states up to 800 g/m² and, because of the bushy, branched growth, recommends systems such as Sea of Green or ScrOG. The manufacturer only describes the height as compact; a figure in centimetres is missing. Good air circulation is expressly recommended: with densely spaced, bushy plants, it pays to thin out lower shoots and keep the air in the canopy moving. The stated yield per area is an upper limit and requires strong light and consistent conditions. You will find the basics on ScrOG, climate and feeding in the Growpedia.
Outdoor Growing
Outdoors, according to the manufacturer, the strain stays compact and still yields up to 1,000 g per plant. In the northern hemisphere, harvest falls in early October. Besides open ground, Green House Seeds also names the greenhouse as a suitable location. A sunny spot with good ventilation helps keep the flowers dry in autumn. The breeder does not give an outdoor height in centimetres. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Great White Shark
Green House Seeds describes the scent of Great White Shark as spicy and earthy with sweet notes. The flavour is intense and classic Indica: slightly sweetish with a deep finish. The manufacturer does not give a lab terpene profile. It describes the effect as a strong, long-lasting body stone that relaxes deeply, and places the strain in the evening. This description goes hand in hand with a comparatively moderate THC value: Green House Seeds states 14.94% THC with 0.18% CBD and 0.25% CBN. If you are used to strains with considerably more THC, you should still not underestimate the body effect. How intense it is depends on dose and individual tolerance.
