Clementine Slush

Clementine Slush Cannabis Seeds by Kannabia

Clementine Slush is a feminised cannabis seed from Kannabia that delivers citrus-drenched terps and a bright, uplifting daytime effect backed by 17–21% THC. Bred from a stacked lineage of California Orange, Tangie, Lemon Skunk, Clementine, and OG Kush, this strain is built for growers who want flavour-forward buds without fussing over a difficult plant. Five seeds per pack — that's enough for a proper pheno hunt or a single confident run.

Clementine Slush Genetics and Lineage

The genetic backbone here reads like a who's who of Californian citrus strains. Kannabia crossed California Orange and Tangie — two of the most recognisable orange-terp cultivars on the planet — with Lemon Skunk for tartness, Clementine for sweetness, and OG Kush for structural backbone and that earthy undertone that stops the citrus from becoming one-dimensional. The result is a sativa-leaning hybrid that grows with indica-like manageability but delivers a clear-headed, stimulating effect you'd expect from its Cali heritage.

We'd compare Clementine Slush most closely to Kannabia's own Citrix or to Dutch Passion's Orange Hill Special — but Clementine Slush edges ahead on aroma complexity. Where Orange Hill Special leans heavily on a single sweet-orange note, Clementine Slush layers fresh-squeezed orange over tart lemon-lime and a Kush earthiness that grounds the whole profile. If you already grow citrus strains and want something with more depth, this is the one.

Growing Clementine Slush Seeds — Indoor and Outdoor

Clementine Slush is a compact, cooperative plant that suits growers with limited vertical space. Indoors, expect heights around 80 cm — short enough for a tent as small as 100 x 100 cm without aggressive training. She'll finish flowering in 60–65 days and return up to 450 g/m² under a decent LED or HPS setup. Outdoors, plants stretch to roughly 140 cm and are ready for harvest by late September to mid-October, yielding up to 500 g per plant in a good season.

One honest note: the fluffy bud structure means you'll want to keep humidity below 50% during late flower. Dense colas trap moisture; airy, sugar-coated buds like these are more forgiving on mould, but they're also more prone to foxtailing under intense light stress. Keep your canopy temperature in check and you'll be rewarded with frosty, resinous nugs covered in vibrant orange pistils.

Aroma, Flavour, and Terpene Profile of Clementine Slush

Crack open a cured jar of Clementine Slush and you'll get hit with a wave of freshly peeled clementine — sweet, bright, almost juicy. Underneath that top note sits a tart lemon-lime sharpness, like biting into a key lime, and a musky Kush earthiness that anchors everything. The terpene profile is dominated by limonene and myrcene, with traces of beta-caryophyllene adding a faint peppery edge on the exhale.

The flavour on combustion or vaporisation follows the nose closely. The inhale is all citrus — orange peel and tangerine zest — while the exhale brings out the earthy, slightly skunky OG Kush base. It's one of those strains where the taste actually lives up to the name, which isn't always the case with "fruit" cultivars. According to research on citrus bioactives, the abundant secondary metabolites in citrus fruit — including limonene — carry a range of beneficial properties (PMC12295204), so the terpene-heavy profile here isn't just about flavour.

Effects and Experience — What to Expect from Clementine Slush

Clementine Slush delivers a clear, stimulating effect that leans heavily sativa. At 17–21% THC, it's potent enough to notice immediately but not so strong that it pins you to the sofa. The onset is quick — a cerebral lift that sharpens focus and makes conversation flow easily. There's a gentle body warmth but zero sedation. This is a morning or afternoon strain, not a nightcap.

Clementine Slush fits that mould. The main side effects reported are dry mouth and dry eyes — nothing a glass of water and some eye drops can't sort. For dosing context, new users often find satisfying effects from the equivalent of 5–10 mg of inhaled THC, while experienced users tend to favour around 15 mg or more.

The one limitation worth mentioning: if you're after heavy body relaxation or a couch-lock indica effect, Clementine Slush isn't your strain. She's built for energy and creativity, not melting into the cushions. For that, you'd be better off looking at something like an OG Kush or a pure indica from the Kannabia range.

Why Clementine Slush Seeds Deserve a Spot in Your Garden

There are dozens of citrus strains on the market. Most of them deliver a vaguely orange smell and an average yield, then call it a day. Clementine Slush actually backs up its name with a five-strain genetic foundation that produces genuinely complex terps — not just "smells a bit like orange." The 450 g/m² indoor yield and 65-day flowering time put it in competitive territory against strains that take 10+ weeks to finish, and the compact 80 cm indoor height means you don't need a cathedral ceiling to grow it.

We've been selling seeds since 1999, and the strains that stick around in our catalogue year after year share two things: they're easy to grow and they taste like something specific. Clementine Slush ticks both boxes. The OG Kush in the lineage gives her enough structural integrity that you're not propping up branches with bamboo stakes every other day, and the Tangie and Clementine genetics ensure every room she's in smells like a citrus grove. Five feminised seeds per pack — no males to cull, no guesswork.

How to Grow Clementine Slush Seeds

1. Germinate seeds using the paper towel method or directly in a starter plug. Keep temperatures between 22–26°C and maintain moisture without waterlogging. Taproots typically emerge within 24–72 hours.
2. Transplant seedlings into their final containers once the first set of true leaves appears. A 3-gallon fabric pot works well for indoor grows; outdoor growers can go larger for bigger yields.
3. Maintain 18/6 light during vegetative growth. At 80 cm final indoor height, Clementine Slush doesn't need an extended veg period — 3–4 weeks is usually enough before flipping to 12/12.
4. Switch to 12/12 to trigger flowering. Expect 60–65 days until harvest. Monitor humidity closely during weeks 5–8; aim for 45–50% RH to protect those fluffy buds from moisture buildup.
5. Harvest when trichomes shift from clear to milky-white with a few amber heads. Dry in a dark room at 18–20°C and 55–60% RH for 7–10 days, then cure in glass jars for at least two weeks to bring out the full citrus terpene profile.
