X-Haze Cannabis Seeds — Classic Haze Genetics With a Citrus Twist
X-Haze is a sativa-dominant feminised cannabis seed from White Label Seeds (Sensi Seeds' sister company) that captures the towering growth and cerebral intensity of old-school 90s Haze genetics, then layers on a bright lemon-citrus aroma inherited from her indica side. At roughly 60% sativa, she grows tall, stretches hard, and finishes with long, wispy colas dripping in resin. If you've been chasing that classic Haze character — the height, the head-rush, the spicy kick — but want something with a bit more flavour complexity, X-Haze is the cross that delivers it.
White Label has been producing no-nonsense genetics for years, and X-Haze sits comfortably in their catalogue as a strain that rewards growers who give her the space and time she needs. She's not a quick-turnaround autoflower. She's a proper Haze hybrid that asks for patience and pays you back in weight, potency, and that unmistakable terpene profile.
X-Haze Seed Pack Sizes — 3 or 5 Seeds
X-Haze is available in two pack sizes:
| Pack | Seeds | SKU |
|---|---|---|
| Standard | 3 feminised seeds | CSWL0055 |
| Value | 5 feminised seeds | CSWL0056 |
If you're running a single indoor grow with a screen setup, 3 seeds is plenty — you'll likely keep 2–3 plants and train them to fill your canopy. Go for the 5-pack if you want to pheno-hunt a bit or run a larger outdoor plot. With a 65–80 day flowering window, having a spare seed or two means you're not starting from scratch if one doesn't germinate.

Growing X-Haze indoors? A ScrOG net is practically mandatory for controlling that Haze stretch. Pair your seeds with a complete grow tent kit if you don't already have a setup — the canopy management alone will make or break your yield with this strain. Also worth grabbing: a carbon filter, because X-Haze's citrus-spice terpene profile is intense enough to announce itself to anyone within sniffing distance.
Why X-Haze Deserves a Spot in Your Grow Room
Here's the thing about Haze strains: they're legendary for a reason, but they're also legendary for being fussy. Tall plants, long flowering times, stretchy growth that can get out of hand in a standard tent. A lot of modern hybrids have bred those traits out in favour of speed and compactness — which is fine, but you lose something in the process. That soaring, clear-headed, almost electric cerebral effect that pure Haze lines deliver? It's hard to replicate with a squat indica-dominant hybrid.
X-Haze threads the needle. White Label kept the height, the stretch, and the head-high intact, but the indica genetics in her background bring a few practical advantages: denser resin production, a slightly more manageable flowering window (65–80 days instead of the 90+ you'd get from a pure Haze), and that gorgeous citrus-forward aroma that pure sativa Hazes don't typically produce. You still need to plan for vertical growth — she will stretch, and she will fill your space — but she's not the unruly monster that some old-school Haze cuts can become.
The honest limitation? She's not a beginner strain. If you've never grown before, X-Haze's long flowering time and height management requirements will test your patience. Compared to something like White Label's Northern Lights, which practically grows itself, X-Haze asks more of you. But if you've got a grow or two under your belt and you want to step up to a proper Haze cross, she's a brilliant next move. The yield-to-quality ratio is excellent once you get the canopy under control.
How X-Haze Smells and Smokes — Aroma and Terpene Profile
This is where X-Haze really sets herself apart from generic Haze crosses. Crack open a cured bud and the first thing that hits you is fresh citrus peel — sharp, bright, almost like squeezing a lemon rind between your fingers. That's the indica heritage showing through, and it's genuinely mouth-watering. Underneath that initial citrus blast, you'll find the classic spicy Haze backbone: warm, peppery, a bit incense-like. As the scent develops, subtle notes of fresh tropical fruit and damp earth round things out.
The resin production is heavy. Those long, wispy sativa flower structures get a dense trichome coating that makes the buds look almost frosted. During the final weeks of flowering, the smell intensifies considerably — if you're growing indoors without carbon filtration, your entire house will know about it. We've seen customers underestimate the odour output of Haze crosses before. Don't be one of them.
The high concentration of THC and terpenes translates directly into the effect: a strong cerebral rush that's uplifting and energetic rather than sedating. White Label describes it as motivating, and that tracks with what you'd expect from a 60% sativa-dominant Haze. It's a morning smoke, a social smoke, a creative-project smoke — not a couch-lock strain by any stretch.
How to Grow X-Haze Cannabis Seeds
- Germination: Use the paper towel method or soak seeds in water for 12–24 hours until taproots emerge. Keep temperatures around 22–25°C and humidity above 70% during germination.
- Seedling stage: Transplant into small pots with a light, airy growing medium. X-Haze responds well to both soil and hydroponic setups. Keep light cycles at 18/6 during vegetative growth.
- Vegetative training: This is critical. X-Haze inherits classic Haze stretch, so start low-stress training (LST) or set up a ScrOG net early. White Label specifically recommends using a screen indoors to control the canopy and increase yield. Top or FIM during veg to encourage lateral branching.
- Flip to flower: Switch to 12/12 light when your screen is roughly 60–70% filled. X-Haze will continue stretching significantly during the first 2–3 weeks of flower — account for this vertical gain when deciding when to flip.
- Flowering (65–80 days): Monitor trichome development with a jeweller's loupe from day 60 onwards. X-Haze produces long, wispy sativa-style colas with heavy resin. Support branches if needed — the buds can get surprisingly weighty for a sativa-dominant plant.
- Outdoor growing: Only viable in warm, Mediterranean-type climates. X-Haze needs a long, warm autumn to finish her flowering cycle outdoors. Northern European growers should stick to indoor cultivation.
- Harvest and cure: Dry in a dark, ventilated space at 18–22°C and 55–60% humidity for 7–10 days. Cure in glass jars for at least 2 weeks — the citrus and spice terpenes develop beautifully with a proper cure.
X-Haze vs Other Haze Strains — How Does She Compare?
If you're weighing X-Haze against other Haze-family seeds, here's how she stacks up in practical terms:
| Trait | X-Haze (White Label) | Amnesia Haze (typical) | Super Silver Haze (typical) |
|---|---|---|---|
| Sativa dominance | ~60% | ~70–80% | ~70% |
| Flowering time | 65–80 days | 70–84 days | 63–70 days |
| Height | Tall (Haze stretch) | Very tall | Tall |
| Primary aroma | Citrus peel, spice | Earthy, citrus, haze | Spicy, herbal, citrus |
| Effect character | Cerebral, uplifting, energetic | Cerebral, creative, intense | Cerebral, energetic, clear |
| Grow difficulty | Intermediate | Intermediate–advanced | Intermediate |
X-Haze's 40% indica contribution gives her a slight edge in resin density and aroma complexity over purer sativa Haze lines. She's also a touch more forgiving in terms of flowering time — 65 days at the short end is quicker than most Amnesia Haze phenotypes. If you want Haze character without committing to a full 12-week flower, X-Haze is the best Haze cross for intermediate growers looking to balance potency, flavour, and a manageable timeline.
Frequently Asked Questions
Is X-Haze sativa or indica?
X-Haze is approximately 60% sativa and 40% indica. She grows like a sativa — tall, stretchy, with long wispy flowers — but the indica genetics contribute to her resin production and citrus-forward aroma. The effect is firmly on the cerebral, uplifting side.
How long does X-Haze take to flower?
X-Haze flowers in 65–80 days. The range depends on phenotype and growing conditions. Check trichomes from day 60 onwards with a loupe — milky trichomes with a few amber ones signal peak harvest for a cerebral effect.
Can I grow X-Haze outdoors in northern Europe?
White Label recommends outdoor growing only in warm, Mediterranean climates. X-Haze's long flowering time means she needs a warm, extended autumn to finish properly. In the Netherlands, UK, or northern Germany, grow her indoors with a ScrOG setup instead.
How tall does X-Haze get indoors?
She inherits classic Haze stretch, so expect significant vertical growth — especially during the first 2–3 weeks of flower. Use a screen (ScrOG) or aggressive LST to keep her manageable. White Label specifically recommends screen growing for indoor cultivation.
What does X-Haze smell like?
The dominant aroma is fresh citrus peel — sharp and lemony. Below that, you'll find a spicy Haze backbone with hints of tropical fruit and earthy undertones. The smell is intense, especially in late flower. A carbon filter is strongly recommended for indoor grows.
Is X-Haze good for beginners?
Honestly, not really. Her Haze stretch, long flowering time, and canopy management needs make her better suited to growers with at least one successful grow under their belt. If you're brand new, start with something more forgiving like Northern Lights, then come back to X-Haze.
What yield can I expect from X-Haze?
White Label rates X-Haze as a heavy yielder, particularly when grown with a screen setup that maximises light exposure across the canopy. Exact grams-per-square-metre depend on your lighting, medium, and training, but the ScrOG method consistently delivers the best results with this strain.
