Auto Lennon Seeds — Jack Herer x Haze in Under 85 Days
Auto Lennon seeds are feminized autoflowering cannabis seeds from Pyramid Seeds that cross Jack Herer with Haze genetics into a compact, fast-finishing plant. The result is a balanced 40% Indica / 30% Sativa / 30% Ruderalis hybrid that goes from seed to harvest in 75-85 days flat — no light schedule changes, no sexing, no fuss. At 10-13% THC, this is a clear-headed, cerebral smoke rather than something that pins you to the sofa. If you want flavour and function without the fiddly grow requirements, Auto Lennon is a solid shout.
Why Grow Auto Lennon Seeds?
We get it — not everyone has a dedicated grow room with programmable timers and six months to spare. Auto Lennon seeds solve the two biggest headaches for home growers in one go: the autoflowering genetics mean the plant flips to flower on its own internal clock (no 12/12 light switch needed), and the feminized seeds mean every single one produces a female plant. No males to spot and pull. No wasted pots, soil, or electricity.
The Jack Herer x Haze lineage gives Auto Lennon a distinctly incense-forward, hazy flavour profile. Think warm, resinous, slightly spicy — the kind of smoke that fills a room. The effect sits squarely in cerebral territory. At 10-13% THC, it's on the mellower end of the spectrum, which actually makes it a better daytime option than most autoflowers that chase big THC numbers at the expense of everything else. You stay functional. You stay present. That's the point.
The honest limitation? Yields. Outdoor plants produce 30-100 grams each — that's a wide range, and the lower end is genuinely modest. Indoor growers can push up to 550 g/m2 under optimal conditions, but "optimal" means proper lighting, good airflow, and dialled-in nutrients. If you're after monster harvests, something like a photoperiod Jack Herer will outproduce this. But if you want a quick, uncomplicated grow with a flavourful payoff, Auto Lennon earns its place.
Auto Lennon Seeds — Growing Tips and What to Expect
Auto Lennon stays compact at 60-110 cm tall, which makes it one of the easier strains to manage in a small tent or on a balcony. The shorter end of that range is typical for indoor grows under 18-20 hours of light; outdoor plants with full sun tend to stretch closer to the 110 cm mark.
Here's what the grow cycle actually looks like:
- Germinate your Auto Lennon seeds using the paper towel method or directly in a small pot of moist, light soil. Taproots usually appear within 24-72 hours.
- Transplant seedlings into their final container early — autoflowers don't love being repotted, so a 7-11 litre pot from the start saves stress. Fabric pots work well for aeration.
- Provide 18-20 hours of light per day indoors for the entire lifecycle. Auto Lennon doesn't need a dark period to trigger flowering — it does that on its own around week 3-4.
- Keep feeding light during veg, then gradually increase nutrients as flowers develop. The Indica influence means the plant stays bushy, so some light defoliation of lower fan leaves helps airflow.
- Harvest at 75-85 days from seed. Check trichomes with a jeweller's loupe — you're looking for mostly cloudy with a few amber heads for that cerebral effect.
One thing we'd flag: because the seed-to-harvest window is so short, Auto Lennon doesn't recover well from early mistakes. Overwatering in the first two weeks or a nutrient burn during early veg can cost you a significant chunk of your final yield. Go easy at the start.
Auto Lennon Flavour Profile and Effects
The terpene profile here leans heavily into incense and classic Haze territory. If you've smoked a proper Haze before, you'll recognise the warm, woody, slightly floral notes on the exhale. It's not fruity, it's not diesel — it's old-school Amsterdam coffeeshop flavour. The kind of smell that clings to your jacket in the best possible way.
The 10-13% THC content puts Auto Lennon firmly in the "functional" category. The effect is cerebral and clear — good for a creative afternoon, a walk, or just pottering around without losing your train of thought. Compared to something like a high-THC auto from the same seed bank, this is a gentler ride. We'd pick Auto Lennon over a 20%+ strain any time the goal is to stay sharp rather than sink into the cushions.

How Auto Lennon Seeds Compare
If you're weighing up Auto Lennon against other autoflowering options, here's how it stacks up against two common alternatives in a similar price range:
| Feature | Auto Lennon (Pyramid Seeds) | Typical Auto Jack Herer | Typical Auto Haze |
|---|---|---|---|
| Genetics | Jack Herer x Haze | Jack Herer x Ruderalis | Haze x Ruderalis |
| THC | 10-13% | 15-20% | 15-18% |
| Seed to Harvest | 75-85 days | 70-84 days | 80-95 days |
| Height | 60-110 cm | 80-150 cm | 90-160 cm |
| Best For | Mellow cerebral smoke, small spaces | Stronger effect, moderate space | Haze flavour, patient growers |
Auto Lennon's lower THC is actually its selling point for a specific type of grower — the one who wants flavour and clarity without getting floored. If you want more punch, a standalone Auto Jack Herer will deliver that, but it'll also grow taller and need more headroom.
Complete your Auto Lennon grow setup with a propagation kit and root stimulator to give seedlings the strongest possible start. If you're growing indoors, a compact grow tent and carbon filter keep things discreet and climate-controlled — autoflowers love consistent conditions.
Frequently Asked Questions
Do Auto Lennon seeds need a specific light schedule?
No. Auto Lennon is autoflowering, so it transitions from vegetative growth to flowering based on age, not light hours. Most growers run 18-20 hours of light per day from seed to harvest for the best results. You never need to switch to 12/12.
How much will one Auto Lennon plant yield?
Outdoors, expect 30-100 grams per plant depending on sunlight and conditions. Indoors under strong lighting, Pyramid Seeds rates the strain at up to 550 g/m2. Realistic first-grow yields tend to sit at the lower-middle end of those ranges.
Is 10-13% THC too low?
Depends what you're after. 10-13% THC gives a clear, cerebral effect — you stay functional and focused. If you're used to 20%+ strains, it'll feel mild. But for a daytime smoke or if you prefer flavour over intensity, it hits the mark.
Can I grow Auto Lennon seeds outdoors in a cooler climate?
Yes. The 75-85 day seed-to-harvest window and compact 60-110 cm height make Auto Lennon viable in shorter summers. As long as your plants get decent sunlight and temperatures stay above 15 degrees Celsius at night, they'll finish before autumn sets in.
Should I top or train Auto Lennon plants?
We'd avoid topping autoflowers — the short lifecycle means they don't recover fast enough. Low-stress training (LST) works better: gently bend the main stem to expose lower branches to light. This can meaningfully improve yields without stressing the plant.
What does Auto Lennon smell like when growing?
Expect warm, resinous incense notes with a classic Haze undertone. It's noticeable but not as pungent as skunk-dominant strains. If you're growing indoors without a carbon filter, your neighbours will likely catch a whiff during the last few weeks of flowering.
