Lemon OG Haze Autoflower Cannabis Seeds
Lemon OG Haze Autoflower is a sativa-dominant autoflowering cannabis seed from Nirvana Seeds that finishes its entire life cycle in just 6-8 weeks from germination. Built on a 5th-generation autoflower lineage — Lemon OG (Las Vegas Lemon Skunk x OG Kush) crossed with Haze 13, then stabilised with AK-48 Automatic — this seed delivers the stretch and vigour of a Haze with the speed and simplicity of a modern auto. Expect yields of 325-425g/m² under an 18/6 light schedule, with flavour notes of fresh lemon peel and pine.
This pack contains 5 feminised autoflowering seeds. Every seed is female — no need to sex plants or remove males. One pack covers a 60x60cm to 80x80cm tent comfortably, or you can spread them across a larger canopy using LST or ScrOG.
Lemon OG Haze Genetics and Lineage
The breeding behind Lemon OG Haze Autoflower is genuinely interesting — it's not a quick rebrand of an existing auto. Nirvana Seeds started with Lemon OG, itself a cross between Las Vegas Lemon Skunk and OG Kush. That pairing gave them a citrus-forward plant with the deep body relaxation OG Kush is known for. They then crossed Lemon OG with Haze 13, pulling in the classic sativa raciness and cerebral energy that Haze genetics deliver. The final step was crossing that Lemon OG Haze with AK-48 Automatic to introduce the autoflowering ruderalis trait.
What you end up with is a 5th-generation autoflower. That matters because early-generation autos were notorious for low yields and weak effects. By the 5th generation, the autoflowering trait is stable and the plant retains far more of the photoperiod parent's character — in this case, the lemon-pine terpene profile and the sativa-leaning effect structure. According to research on cannabis terpene profiles, pinene and limonene — both present in lemon-forward strains — have been studied for potential anti-inflammatory properties in animal models (Khaleel et al., 2021).

Growing Lemon OG Haze Autoflower Seeds
This strain stretches more than most autoflowers during flowering — that's the Haze 13 genetics coming through. In a 60x60cm tent, you'll want to start low-stress training (LST) early, bending the main stem to open up the canopy. ScrOG (Screen of Green) works well too: install a net at about 30cm height and tuck branches under it as the plant stretches. Without training, you'll end up with one tall cola shading everything below it.
The good news: despite the extra stretch, this is still an autoflower. It won't reach the 150cm+ heights of photoperiod Haze plants. Nirvana recommends an 18/6 light schedule throughout the entire grow — no need to flip to 12/12. The plant handles its own timing. With a 6-8 week life cycle from seed, you can realistically run 4-5 cycles per year in the same tent.
Yields land between 325-425g/m², which is solid for an auto — especially one with this much sativa influence. To hit the upper end of that range, keep the environment dialled in: 20-26°C, relative humidity dropping from 60% in veg to 40-45% in late flower, and consistent 18 hours of light. A quality LED panel makes a real difference here. We'd pick a 100W-150W board for a 60x60 tent, or 240W+ for an 80x80.
Flavour and Terpene Profile of Lemon OG Haze
Open a jar of dried Lemon OG Haze and the first thing that hits you is fresh lemon peel — not candy lemon, not cleaning product lemon, but the sharp citrus burst you get from zesting a real lemon over a plate. Underneath that sits a pine note, resinous and slightly sweet, which is the OG Kush side making itself known. The smoke is smooth and fruity, without the harsh throat hit some Haze crosses can deliver.
That lemon-pine combination points to a terpene profile rich in limonene and pinene. According to a review published in Frontiers in Pharmacology, pinene and linalool have shown analgesic and anti-inflammatory effects in preclinical (animal) models following exogenous application of irritants (Khaleel et al., 2021). And a study on cannabis terpenes noted that beta-caryophyllene — a common sesquiterpene in cannabis — interacts with CB2 receptors, which has drawn research interest for its potential role in inflammation modulation (Sommano et al., 2020).
A study examining subjective responses to cannabis cultivars found that Super Lemon Haze — a related lemon-Haze cross — was frequently associated with mood-lifting subjective reports among users, though the researchers noted that flavour expectation and terpene content likely both contributed to these perceptions (de la Fuente et al., 2020). Worth keeping in mind: subjective experience varies, and the entourage of terpenes and cannabinoids matters more than any single compound.
| Flavour/aroma note | Likely terpene | Character |
|---|---|---|
| Fresh lemon peel | Limonene | Sharp, citrus, zesty |
| Pine resin | Alpha-pinene | Woody, slightly sweet |
| Peppery undertone | Beta-caryophyllene | Spicy, warm |
| Smooth fruit | Myrcene (probable) | Mango-like, earthy |
Why Grow Lemon OG Haze Autoflower
The honest pitch: if you want a Haze-leaning smoke without the 12-14 week flowering time and 2-metre height that photoperiod Hazes demand, this is one of the better autoflower options. The 6-8 week life cycle means you can go from cracking a seed to trimming buds in under two months. For growers running small tents — the 60x60 or 80x80 setups we sell the most of — that speed and manageable height are genuinely practical advantages.
The OG Kush in the genetics adds body to what would otherwise be a purely cerebral, racy Haze experience. Nirvana describes it as a blend of "narcotic Kush and uplifting Haze," and that's a fair summary. You get the energising onset from the Haze side, followed by a deeper physical relaxation from the Kush lineage. It's a more complete smoke than a pure sativa auto.
One honest limitation: 325-425g/m² is good for an auto, but it's not going to match a photoperiod Lemon Haze grown in the same space. Photoperiod versions from other seed banks can push 450-600g/m² indoors with longer veg times. You're trading yield ceiling for speed and simplicity. For most home growers, that's a trade worth making — but if you're chasing maximum grams per watt, a feminised photoperiod might serve you better.
How to Grow Lemon OG Haze Autoflower Seeds
- Germinate seeds using the paper towel method or directly in a small pot of moist, light soil mix. Autoflowers don't transplant well, so if you start in a small pot, move to the final container within the first week — before the taproot gets established.
- Plant into your final container. An 11-15 litre fabric pot is the sweet spot for most autoflower grows. Fabric pots air-prune roots and prevent the circling you get in plastic pots.
- Set your light schedule to 18 hours on, 6 hours off from day one. Keep it there for the entire grow — Nirvana specifically recommends 18/6 for this strain.
- Begin low-stress training once the plant has 4-5 nodes. Gently bend the main stem away from centre and secure it with soft plant ties. This opens the canopy and encourages side branches to develop into secondary colas.
- Watch for the stretch during early flowering — this strain extends more than typical autos. If using ScrOG, tuck branches under the net every day or two during this phase.
- Reduce humidity to 40-45% once buds start forming. The dense Kush-influenced bud structure can hold moisture, so good airflow is critical in the final 2-3 weeks.
- Harvest when trichomes are mostly cloudy with a few turning amber. The 6-8 week timeline is a guide — check trichomes with a jeweller's loupe rather than counting days.
Complete your setup with a grow tent and LED panel if you haven't already — an 80x80cm tent gives you room for all 5 seeds with training, and a 240W LED board will push yields towards the upper end of that 425g/m² range. A carbon filter is worth grabbing too: Lemon OG Haze puts out a strong citrus aroma in late flower that your neighbours will notice without one.
Frequently Asked Questions
How long does Lemon OG Haze Autoflower take from seed to harvest?
6-8 weeks from germination. That's the full life cycle — no separate veg and flower phases to manage. Actual harvest timing depends on your setup, but most growers report chopping around week 7-8.
What yield can I expect from Lemon OG Haze Autoflower indoors?
Nirvana rates it at 325-425g/m² under an 18/6 light schedule. Hitting the upper range requires good lighting (200W+ LED for an 80x80 tent), proper training, and stable environmental conditions throughout the grow.
Does Lemon OG Haze Autoflower stretch a lot during flowering?
Yes — more than most autoflowers. The Haze 13 genetics give it a noticeable sativa stretch in early flower. Low-stress training or ScrOG is strongly recommended if you're working in a tent under 120cm tall.
What light schedule should I use for Lemon OG Haze Autoflower?
Nirvana recommends 18 hours of light and 6 hours of dark (18/6) for the entire grow cycle. Some growers run 20/4 for autos, but 18/6 is what the breeder suggests for this specific strain.
What does Lemon OG Haze Autoflower smell and taste like?
Fresh lemon peel is the dominant note — sharp citrus, not sweet or artificial. There's a pine resin undertone from the OG Kush side, and the smoke itself is smooth and fruity. Expect strong aromas in late flower; a carbon filter is a good idea.
Is Lemon OG Haze Autoflower good for beginners?
Reasonably, yes. The autoflowering trait removes the need to manage light cycle changes, and the 6-8 week timeline means fewer weeks where things can go wrong. The main thing to watch is the sativa stretch — train early or you'll run out of vertical space in a small tent.
How does Lemon OG Haze Autoflower compare to photoperiod Lemon Haze?
The auto version trades yield ceiling and maximum potency for speed and simplicity. Photoperiod Lemon Haze strains can push 450-600g/m² but take 10-14 weeks of flowering alone, plus veg time. The auto does everything in 6-8 weeks total, which suits small-space and multi-cycle growers.
