What is the Great White Shark strain?
Great White Shark is an indica-leaning hybrid from Green House Seeds in Amsterdam, bred from Super Skunk and the Brazilian × South Indian genetics of White Widow. Green House describes its effect as a very strong, long-lasting body stone. The strain flowers in roughly 65 to 70 days indoors, yields 500 to 800 g/m² by the breeder's figures, and has been listed anywhere from 14% THC in early breeder notes to about 23% in current ones.
Ratio from Zamnesia's Green House Seeds data sheet and AllBud. Leafly files Great White Shark under sativa, so the split is debated.
Green House sums up Great White Shark's effect as a very strong body high, stoned and long lasting.

Where does the Great White Shark strain come from?
Great White Shark was bred by Green House Seeds in Amsterdam by crossing a selected Super Skunk plant with the breeder's own White Widow. Green House writes the pedigree as Super Skunk × Brazilian × South Indian, which describes the same cross: White Widow itself comes from a Brazilian sativa and a South Indian indica. Super Skunk is Sensi Seeds' Skunk #1 × Afghani, so Great White Shark also carries the Skunk #1 and Afghani genetics behind that parent.
The strain was well established by 1997, when Green House's Tolstraat coffeeshop entered Great White Shark in the High Times Cannabis Cup. Green House still sells Great White Shark seeds today. AllBud lists White Shark as another name for the strain, and Leafly's Great White Shark page uses white-shark in its web address.
Did Great White Shark win the Cannabis Cup?
Great White Shark placed second, not first, at the 1997 High Times Cannabis Cup. The published 1997 results list it in second place in both the main Cannabis Cup and the Bio Cup, entered by Green House Tolstraat. Retailer listings for the Green House seeds also report first places at the 2005 Highlife Cup, in the Super Cup and seed-company hydro categories.
About the "Best Hybrid" claim. Some strain sites say Great White Shark won Best Hybrid or first place in 1997; the published results table for that year doesn't support either claim.

- Body-heavy
- Euphoric
- Happy
- Relaxed
- Sleepy
The side effect Leafly reviewers mention most for Great White Shark is the munchies; AllBud reviewers also note a harsh aftertaste and smoke that sits heavy in the throat, and dry mouth is common.

How do you grow Great White Shark seeds?
Great White Shark seeds grow into medium-height, heavy-yielding plants that are moderately easy to manage: top them in veg, flower for about 9 weeks, and keep humidity low because the big, dense colas are the main risk late in bloom.
- GerminateAbout 1 week
Great White Shark seedlings are sturdy; give them gentle light for the first days and move them to full strength once the second leaf set opens.
- Vegetate4–5 weeks indoors
Top Great White Shark once and spread the branches so several main colas form instead of one oversized top bud.
- Flower8–10 weeks
Great White Shark bulks up fast in the second half of bloom; add support for heavy branches and keep air moving between the colas.
- HarvestAround day 65 indoors · late Sept–early Oct outdoors
Most Great White Shark growers harvest around day 65; Green House notes that one more week adds resin and sweetness.
Grow tips for Great White Shark
- Guard the big colas. Great White Shark builds large, dense buds that hold moisture. Keep late-flower humidity low and remove inner leaves that block airflow.
- Stake before week 5. With breeder yields of up to 800 g/m², Great White Shark branches can bend under their own weight. Add a trellis or stakes early in flower.
- Decide on the extra week. Harvest Great White Shark at about day 65 for a balanced effect, or wait a week longer, as Green House suggests, for more resin and a sweeter taste.
- Control the skunk smell. The Super Skunk side makes Great White Shark pungent in flower, so run a carbon filter indoors and think about neighbors outdoors.
- Finish before autumn rain. Outdoors, Great White Shark is ready from the end of September, which suits temperate gardens if the weather stays dry into early October.

Great White Shark strain FAQ
Is Great White Shark indica or sativa?
Great White Shark is usually listed as an indica-dominant hybrid, about 80% indica and 20% sativa according to Zamnesia's Green House data sheet and AllBud. Leafly files it under sativa, but the heavy body effect most users report fits the indica-leaning label.
What are the parents of Great White Shark?
Great White Shark is a cross of Super Skunk and White Widow, bred by Green House Seeds. Green House often writes the pedigree as Super Skunk × Brazilian × South Indian, because White Widow itself comes from a Brazilian sativa and a South Indian indica.
Did Great White Shark win the Cannabis Cup?
Great White Shark placed second at the 1997 High Times Cannabis Cup, in both the main Cannabis Cup and the Bio Cup. Green House Seeds' retailers also list first places at the 2005 Highlife Cup. Claims of a 1997 first place or Best Hybrid title don't match the published results.
How much THC does Great White Shark have?
Great White Shark has been listed between about 14% and 23% THC. Green House's early listing gave 14% THC with 1.7% CBD, AllBud gives 15–21%, and current Green House listings give about 23%. Potency depends on the plant and the grow.
How long does Great White Shark take to flower?
Great White Shark flowers in about 8 to 10 weeks indoors after the switch to 12/12. Green House says most growers harvest around day 65, and that one extra week adds resin and sweetness. Outdoors it is ready from the end of September.
How much does Great White Shark yield?
Green House Seeds lists Great White Shark at 500 to 800 g/m² indoors, and as much as 1 kg (about 2.2 lb) from a single outdoor plant. Those are the breeder's best-case figures; your harvest depends on light, plant count and training.
Is White Shark the same as Great White Shark?
Usually, yes. AllBud lists White Shark as another name for Great White Shark, and Leafly's Great White Shark page uses white-shark in its web address. Other seed companies sell different crosses with shark names, so check the pedigree: the Green House strain is Super Skunk × White Widow.
What does Great White Shark smell like?
Great White Shark smells skunky and sweet, with fruit, citrus and floral notes, plus a faint wintergreen edge that Green House mentions in its description. Myrcene, humulene and caryophyllene are its main terpenes.
