Greenhouse Seeds Lemon Orange Cannabis Seeds
Lemon Orange is a sativa-dominant cannabis seed strain from Greenhouse Seeds that delivers exactly what the name promises — a full citrus explosion backed by a staggeringly high THC content of over 29%. Bred from Super Lemon Haze crossed with Clementine, this 70% sativa hybrid packs serious genetics into a surprisingly fast-flowering plant. Indoor growers get harvest-ready buds in just 9 weeks, while outdoor plants can produce up to 800g per plant by mid-October. If you want citrus terps dialled up to eleven with genuine potency to match, this is the seed to grow.
Choose Your Pack Size
Lemon Orange seeds come in three pack sizes. Grab 3 seeds if you want to run a single pheno hunt or a small personal grow. The 5-pack gives you enough to select the best mother plant with a couple of spares. Go with 10 seeds if you're filling a tent or planning successive grows — and it works out cheaper per seed.
| Pack | Seeds | Best For |
|---|---|---|
| 3 Seeds | 3 | Small personal grow, single-plant setup |
| 5 Seeds | 5 | Pheno selection with room for extras |
| 10 Seeds | 10 | Full tent, multiple runs, best per-seed value |
Lemon Orange Genetics and Lineage
Lemon Orange cannabis seeds carry a pedigree that citrus chasers will appreciate immediately. The mother side is Super Lemon Haze — a two-time Cannabis Cup winner known for its sharp, zesty lemon profile and energetic effects. The father is Clementine, a sativa-leaning strain celebrated for its sweet orange aromatics and sky-high terpene production. The result is a 70/30 sativa-dominant hybrid that inherited the best traits from both parents: tangy lemon on the inhale, sweet earthy orange on the exhale, and a terpene profile dominated by terpineol, d-limonene, and caryophyllene.
Greenhouse Seeds is one of the longest-running seed banks in the Netherlands, and they've clearly put this cross together with flavour hunters in mind. The limonene content alone sets Lemon Orange apart from most sativa hybrids on the market — you can smell the citrus influence well before harvest, during the final weeks of flowering when the buds start throwing off a pleasant sweetness that fills the grow room.

Growing Lemon Orange Cannabis Seeds
Lemon Orange seeds produce plants that grow like a proper sativa — tall, branchy, and hungry for light — but with one critical advantage over most sativa-dominant strains: a flowering time of only 9 weeks. That's unusually short for a 70% sativa. Most sativa-leaning hybrids push 10 to 12 weeks in flower, so shaving that down to 9 means faster turnaround without sacrificing yield or potency.
Indoors, expect plants to stretch up to 2 metres if left untopped. The structure is robust with strong side branches that develop heavy bud sites — these branches hold their own weight well, though some support in the final 2 weeks of flower won't hurt given the sheer volume of buds this strain produces. If vertical space is limited, top early and consider a SCROG net to keep the canopy even. The branchy side growth responds brilliantly to training.
Outdoors is where Lemon Orange really shows off. In a warm climate with full sun, individual plants can yield up to 800g — that's a serious haul by any standard. Harvest falls around mid-October, which is manageable for most Southern European and Mediterranean growers. Northern European outdoor growers should keep an eye on autumn humidity; those dense bud clusters can trap moisture if you're not careful.
One honest note: at 29%+ THC, this strain demands proper drying and curing to bring out the full terpene profile. Rush the cure and you'll get potency but miss the layered citrus flavour that makes Lemon Orange special. Give it at least 2 weeks of slow drying and another 2-4 weeks in jars. The patience pays off.
Flavour, Aroma, and Terpene Profile
Lemon Orange cannabis seeds produce buds with one of the most distinct citrus profiles we've come across. The terpene trio of d-limonene, terpineol, and caryophyllene creates a layered sensory experience that goes well beyond "it smells lemony." On the inhale, you get a sharp, tangy lemon hit — think fresh lemon zest, not lemon candy. The exhale shifts to a sweeter, earthier orange note, with just enough spice from the caryophyllene to ground the whole thing. It's the right balance of sweet, sour, and earthy without any single note dominating.
During the final weeks of flowering, the plants themselves start broadcasting this citrus profile. The grow room takes on a pleasant, sweet-citrus scent that intensifies daily. If you're growing in a tent, your carbon filter will be earning its keep. Once dried and properly cured, those aromas concentrate and the flavour really opens up — this is a strain where proper post-harvest handling makes a noticeable difference to the end product.
Compared to something like Amnesia Haze, which leans more towards a hazy, incense-like citrus, Lemon Orange is cleaner and more fruit-forward. If you've grown Super Lemon Haze before, imagine that lemon sharpness softened and sweetened by the Clementine genetics. It's a genuine flavour strain that also happens to carry 29%+ THC — that combination is rarer than you'd think.
Running Lemon Orange in a tent? Pair these seeds with a complete grow tent kit for a ready-to-go indoor setup. The citrus terps on this strain are loud — a carbon filter and extraction fan are not optional if discretion matters. For outdoor growers, a set of plant support stakes will help those heavy branches through the final weeks of flower.
Why Lemon Orange Deserves a Spot in Your Grow
The cannabis seed market is flooded with strains that promise big flavour and big yields. Most of them deliver one or the other — rarely both. Lemon Orange is one of those uncommon strains where the marketing actually lines up with the genetics. You get genuine citrus terps from a proven lineage (Super Lemon Haze x Clementine), a 9-week flowering time that's unusually fast for a sativa-dominant plant, and a THC content north of 29% that puts it in the top tier of potency.
The 800g outdoor yield potential is the other standout figure. Most sativa-dominant strains that flower in 9 weeks produce moderate yields at best — the short flowering window usually means smaller harvests. Lemon Orange breaks that pattern. The robust side branching and vigorous growth during veg translate into heavy harvests even with the compressed flowering schedule.
We'd pick Lemon Orange over a standard Super Lemon Haze grow for one simple reason: you get 90% of the flavour profile with a faster turnaround and better structural integrity. Super Lemon Haze plants tend to get lanky and floppy under bud weight. Lemon Orange's Clementine genetics add sturdier branching and a touch of sweetness to the flavour that rounds out the sharp lemon edge. For growers who want a citrus sativa without the 11-week wait, this is the one.
How to Grow Lemon Orange Seeds
- Germinate your Lemon Orange seeds using the paper towel method or directly in a starter plug. Maintain a temperature of 22-26 degrees Celsius and keep the medium moist but not waterlogged. Taproots typically emerge within 24-72 hours.
- Transplant seedlings into their final containers once the first set of true leaves appears. For indoor grows, 15-20 litre pots give the root system enough room to support the plant's vigorous sativa growth pattern.
- During the vegetative stage, top the plant once above the 4th or 5th node to encourage lateral branching. Lemon Orange responds well to LST (low-stress training) and SCROG setups — both help manage the height and maximise light exposure across the canopy.
- Switch to a 12/12 light cycle to trigger flowering. The 9-week flowering period begins from the flip. Watch for significant stretch during the first 2-3 weeks of flower — plants can nearly double in height during this phase.
- In the final 2 weeks of flowering, monitor bud density carefully. The heavy bud clusters may need support from stakes or a trellis net. This is also when the citrus aroma intensifies noticeably.
- Harvest when trichomes show a mix of milky white and approximately 10-15% amber under magnification. Dry slowly at 18-20 degrees Celsius and 55-60% humidity for 10-14 days, then cure in airtight jars for a minimum of 2-4 weeks to develop the full lemon-orange terpene profile.
Frequently Asked Questions
What does Lemon Orange taste like?
Sharp, tangy lemon on the inhale followed by sweet, earthy orange on the exhale. The dominant terpenes — d-limonene, terpineol, and caryophyllene — create a layered citrus profile with a touch of spice. Proper curing for 2-4 weeks brings out the full flavour complexity.
How long does Lemon Orange take to flower?
Lemon Orange has a flowering time of 9 weeks indoors, which is notably short for a 70% sativa-dominant strain. Outdoors, harvest falls around mid-October. The compressed flowering schedule doesn't come at the expense of yield — outdoor plants can still produce up to 800g each.
How tall does Lemon Orange grow?
Plants can reach up to 200cm (2 metres) if left untopped. Indoor growers with limited headroom should top early and use LST or a SCROG net to manage height. The strong side branching responds well to training techniques.
What is the THC level of Lemon Orange?
Lemon Orange produces buds with a THC content exceeding 29%. That puts it among the strongest strains currently available from Greenhouse Seeds. Even experienced users should approach the first session with respect — the potency is genuinely high.
Is Lemon Orange suitable for beginner growers?
It's manageable for beginners with some research behind them. The robust structure and strong branches make it forgiving, and the 9-week flowering time reduces the window for things to go wrong. The main challenge is managing height indoors — topping and training are strongly recommended if you're working in a tent.
What are the parent strains of Lemon Orange?
Lemon Orange is a cross between Super Lemon Haze and Clementine, both renowned citrus strains. Super Lemon Haze is a two-time Cannabis Cup winner with sharp lemon terps, while Clementine contributes sweet orange aromatics and vigorous growth. The combination produces a 70/30 sativa-dominant hybrid.
How much does Lemon Orange yield outdoors?
In optimal outdoor conditions with full sun, Lemon Orange can yield up to 800g per plant. Harvest timing is mid-October. Growers in humid climates should watch for moisture trapped in the dense bud clusters during the final weeks before harvest.
