A Fast, Zesty Take on a Haze Legend
Super Lemon Haze is a multi-cup-winning sativa famous for its sharp lemon zest and soaring, energetic high. The one drawback of pure hazes has always been a long bloom, and this auto version fixes that by pairing the strain with ruderalis for a quick, hands-off grow with the same citrus character.
For a grower, that means the classic lemon-haze experience on a timeline that fits real life. If you want the original in feminized photoperiod form, the award-winning Super Lemon Haze is its parent and a rewarding companion grow for when you can give it more time.
Climate and Where to Grow It
Super Lemon Haze Auto does best in a dry, warm climate, which suits its haze genetics and helps keep its airy flowers clean. It performs both outdoors in an arid, sunny season and in a controlled indoor tent, though you should plan for its height, since it stretches tall like a true sativa.
Low humidity is its friend: dry air keeps the long, resinous colas healthy and reduces the risk of mould on the dense flower clusters. Outdoors a single plant brings in a modest 120–200 g, while indoors, where you can control the environment, it produces a strong 550–600 g/m².
Indoors, aim for daytime temperatures around 75–85°F (24–29°C), keep the air on the drier side, and maintain steady airflow through the tall canopy. Because it grows big for an auto, light training early on helps spread the plant out and keep every bud site in good light.
Growing Autoflowering Seeds
As an autoflower, Super Lemon Haze Auto flowers automatically with age rather than on a change in the light schedule. That removes the biggest decision of a photoperiod grow: you never flip the lights, and the plant simply moves into bloom on its own after a few weeks of early growth.
You can run it under a long day, around 18–20 hours of light, for its entire life, which keeps energy high right through flowering. Start it in its final pot to avoid transplant shock, since autos do not like having their quick life cycle interrupted, and feed gently while young. From seed to harvest the whole run takes about 8–10 weeks.
Feeding Schedule (EC Guide)
This is a vigorous auto that can take a steady feed through bloom, but it still prefers a lighter hand than a heavy photoperiod plant. Start low, build up gradually as it enters flower, and taper off for the final flush so the bright lemon-citrus flavour comes through clean and sharp.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4–0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8–1.2 | Build the frame, raise nitrogen gradually |
| Early flower | 1.2–1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4–1.6 | Peak bloom feed while the long colas swell |
| Flush | 0.0–0.4 | Plain water for the final 1–2 weeks |
Flowering and Harvest
Because it autoflowers, Super Lemon Haze Auto sets its own pace, with the full cycle running about 8–10 weeks from seed. As a sativa-dominant plant it stretches hard as it enters bloom, then fills in long, slender, resin-flecked colas rather than the dense, chunky buds of an indica.
Give the tall structure some support as the colas gain weight, and keep the canopy open so light reaches the lower flowers. Harvest when most trichomes have turned milky-cloudy with a few amber heads for the fullest expression, and run a short plain-water flush in the last week or two before you cut it down.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15–18°C) and 55–60% humidity for 7–14 days, until the thin stems snap rather than bend. A slow, even dry preserves the bright, lemony haze terpenes, which can fade fast if the airy buds are dried too hard or too quickly.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure brings the zesty citrus and sweet notes forward and smooths the smoke, which is exactly what this haze-rooted autoflower deserves after its quick finish.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Super Lemon Haze Auto is an aromatic, resinous plant, so the trim is well suited to dry sift, bubble hash or rosin, giving you a bonus run of zesty, citrus-forward concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
Super Lemon Haze Auto has a bright, zesty lemon-citrus flavour with a clean sweet finish, exactly the fresh, mouth-watering profile that made its parent a favourite. It is a sharp, lively taste rather than a heavy or earthy one, and it pairs naturally with the strain’s energetic, uplifting character.
It carries a focused terpene stack, and all three of its terpenes shape the flavour. Terpinolene drives the zesty citrus and lemon lift; myrcene adds a ripe, sweet depth that rounds out the sharpness; and caryophyllene folds in a gentle peppery spice underneath, giving the bright lemon profile a little warmth and backbone.
Effects and Best Use
With its sativa-dominant genetics, Super Lemon Haze Auto is reported as creative, energetic and uplifted, a bright, feel-good lift carried straight over from its Super Lemon Haze parent. It leans firmly toward daytime and creative use, giving a clear-headed, motivating buzz without a heavy, couch-bound finish.
At a medium 16–20% THC it is approachable rather than overpowering, which suits less experienced users and anyone who prefers a functional, energising high. That balance, the quick auto life cycle, the strong indoor yield and the standout lemon-citrus flavour are exactly why growers reach for this strain.
FAQ
Is Super Lemon Haze Auto an autoflower?
Yes. Super Lemon Haze Auto is an autoflowering strain, so it flowers automatically with age rather than on a light change. You can keep it under a long 18–20 hour light schedule for its whole life, and it runs from seed to harvest in about 8–10 weeks, with no need to flip the lights.
How long does Super Lemon Haze Auto take to flower?
As an autoflower, its full cycle runs about 8–10 weeks from seed to harvest, fast for a lemon haze. That speed is a major draw, since classic Super Lemon Haze needs a long photoperiod bloom, while this auto delivers the same zesty, uplifting character on a far quicker, simpler timeline.
Is Super Lemon Haze Auto indica or sativa?
It is strongly sativa-dominant, at roughly 80% sativa and 20% indica, which it keeps from its Super Lemon Haze parent. That shows in a tall, lively plant and a creative, energetic, uplifting effect, with just a touch of indica to round it out, making it a classic daytime, feel-good strain.
What yield can I expect from Super Lemon Haze Auto?
Indoors it is a strong producer for an auto, giving around 550–600 g/m² with good light and an open canopy. Outdoors yields are more modest at roughly 120–200 g per plant, so most growers get the best return from this tall, lively plant in a well-lit indoor tent.
What does Super Lemon Haze Auto taste like?
Expect a bright, zesty lemon-citrus flavour with a clean sweet finish, exactly the fresh profile that makes this strain so popular. Terpinolene drives the zesty citrus lift, myrcene adds a ripe, sweet depth, and caryophyllene folds in a gentle peppery spice underneath the lemon.
Does Super Lemon Haze Auto grow tall?
Yes, for an autoflower it is notably tall, reaching around 4.92 ft (1.5 m) in line with its sativa haze genetics. Plan for that stretch indoors with headroom or early low-stress training, and the extra height helps it build the long, zesty colas it is known for.
