Black Haze Autoflower Seeds by Exotic Seed
Black Haze is an autoflowering cannabis seed strain from Exotic Seed that delivers stunning dark-hued plants with a sweet-and-sour aroma and an uplifting, focused effect. Created by crossing Auto Sir Jack with a Pakistan Chitral Kush hybrid, this compact cultivar grows to just 80–100cm and finishes without photoperiod changes — making her one of the most visually striking autos you can grow in a small space.
This pack contains 3 feminised autoflowering seeds. Every seed is female — no males to cull — and flowers automatically regardless of light schedule.
Why Black Haze Autoflower Seeds Stand Out
Plenty of autoflowers are bred for speed or yield. Black Haze was bred for looks and flavour first, and it shows. The plant develops red, purple, and near-black hues across her calyxes and fan leaves as she matures — the kind of colours that make you stop and stare when you open the tent. Exotic Seed achieved this by bringing in Pakistan Chitral Kush genetics, a landrace-derived line famous for its dramatic pigmentation at cooler temperatures.
The aroma is equally distinctive. Expect a blend of sweet and sour notes layered with hashy, incense-like undertones. It's not your standard fruity auto smell — there's genuine complexity here, closer to what you'd expect from a photoperiod strain with proper breeding behind it. When smoked, that sweet-sour profile carries through with a lingering hash finish on the exhale.
The effect leans cerebral: energising, uplifting, and good for staying focused or working on something creative. The Indica side from the Pakistan Chitral Kush adds a mild physical relaxation underneath — enough to take the edge off without pulling you into the sofa. We'd call it a daytime smoke, or at least an early-evening one. You're not going to lose the afternoon.
The honest limitation? Yields are moderate. Exotic Seed lists an average of 375g/m², with 400g/m² achievable in optimised indoor setups. If you're chasing weight above all else, something like a Big Bud auto will outproduce her. But if you want a plant that looks extraordinary, smells genuinely interesting, and delivers a balanced effect you'll actually enjoy — Black Haze earns her spot.

Growing Black Haze Autoflower Seeds
Black Haze autoflower seeds are genuinely easy to grow — one of the better choices if you're running your first auto or just want a low-maintenance plant in the rotation. She doesn't demand much fuss, but a few pointers will help you get the most from her.
- Germinate your Black Haze seeds using the paper towel method or directly in a small pot of moist, aerated soil. Taproots typically emerge within 24–72 hours.
- Transplant seedlings into their final container early — 11–15 litre fabric pots work well. Autos don't love being repotted once established, so minimise root disturbance.
- Run an 18/6 or 20/4 light schedule indoors for the entire lifecycle. Black Haze is autoflowering, so she'll begin flowering on her own after roughly 3–4 weeks of vegetative growth regardless of light hours.
- Keep feeding light to moderate. She's a compact plant (80–100cm) and doesn't need heavy nutrient loads. Overfeeding is the most common mistake we see with smaller autos — watch the leaf tips.
- Drop nighttime temperatures by a few degrees during late flowering if you want to maximise those signature purple and black hues. The Pakistan Chitral Kush genetics respond well to cooler nights (around 15–18°C).
- Harvest when trichomes are mostly milky with a few amber — this preserves the uplifting, cerebral character. Waiting until mostly amber will push the effect heavier and more sedative.
Outdoors, she'll do well in most European climates from late spring through summer. The 80–100cm height makes her easy to tuck onto a balcony or into a small garden plot without drawing attention. No supplemental lighting needed — she flowers on her own schedule.
Black Haze Aroma and Effect Profile
The terpene profile of Black Haze delivers a distinct sweet-and-sour aroma with exotic, hashy incense notes — a combination you don't often find in autoflowering strains. According to research on cannabis terpenes published in Molecules (PMC7763918), terpene composition varies significantly between cultivars and directly shapes both aroma and the character of the experience.
The effect is primarily cerebral and uplifting. Users report an energising, creativity-friendly head effect paired with a subtle body relaxation from the Indica-side genetics. It's the kind of smoke that suits a weekend afternoon project or a long walk — present and focused, not foggy. The Pakistan Chitral Kush heritage contributes just enough physical ease to smooth things out without tipping into couch-lock territory.
According to research on secondary terpenes in Cannabis sativa (PMC9775512), monoterpenes like sabinene — associated with spicy flavour and aroma — contribute to the varied sensory profiles found across different cannabis cultivars. Black Haze's complex incense-like notes suggest a terpene mix that goes beyond the usual myrcene-heavy auto profile.
Black Haze Compared to Similar Autoflower Strains
Choosing between autoflower strains usually comes down to what matters most to you: yield, flavour, effect, or appearance. Here's how Black Haze stacks up.
| Feature | Black Haze (Exotic Seed) | Typical High-Yield Auto | Typical Indica Auto |
|---|---|---|---|
| Height | 80–100cm | 100–120cm | 60–80cm |
| Yield (Indoor) | 375–400g/m² | 450–550g/m² | 300–400g/m² |
| Effect | Uplifting, cerebral, mild body | Varies | Heavy body, sedative |
| Aroma | Sweet, sour, hashy incense | Varies | Earthy, kushy |
| Appearance | Red, purple, near-black hues | Standard green | Compact, dark green |
| Growing Difficulty | Easy | Easy–Moderate | Easy |
If maximum grams per square metre is your priority, Black Haze isn't the one — she tops out around 400g/m² in ideal conditions. But if you want a plant that genuinely looks different, smells interesting, and delivers an effect you'll reach for again, she's hard to beat in the autoflower category. We'd pick her over a generic high-yield auto every time for personal-use grows where quality matters more than quantity.
Complete your grow setup with a propagation kit to give your Black Haze seeds the best start, and a carbon filter if you're growing indoors — that sweet-sour aroma is lovely, but your neighbours might have opinions. A set of fabric pots in the 11–15 litre range pairs well with compact autos like this one.
Dosing and Potency Notes for Black Haze
Black Haze is a potent sativa-dominant hybrid. According to competitive strain databases, THCV content has been measured at 0.28–0.54%, and the strain is generally recommended for experienced consumers — newcomers should start with a small amount and wait before taking more. Expert resources on Black Haze genetics advise careful dosing, particularly for those unfamiliar with cerebral, energising strains.
The uplifting, focused character means overconsumption is more likely to produce racing thoughts than heavy sedation. If you're new to sativa-leaning strains, a single small inhalation followed by a 15-minute wait is a sensible approach.

Is Black Haze easy to grow for beginners?
Yes. She's an autoflower that doesn't need light schedule changes, stays compact at 80–100cm, and handles both indoor and outdoor environments without fuss. One of the more forgiving strains to start with.
How do I get the purple and black colours on Black Haze?
The dark pigmentation comes from the Pakistan Chitral Kush genetics. Dropping nighttime temperatures to around 15–18°C during late flowering encourages the most dramatic colour expression. She'll still show some colour at standard temperatures, but the cold really brings it out.

Primarily cerebral, energising, and uplifting — good for creative focus. The Indica genetics add a mild physical relaxation without sedation. It's a daytime-friendly strain that won't knock you out.
How tall does Black Haze grow?
Between 80 and 100cm in most conditions. This makes her well-suited to small tents, balconies, or discreet outdoor spots where height is a concern.
