Siberian Haze Auto Cannabis Seeds
Siberian Haze Auto is an autoflowering cannabis seed from Kalashnikov Seeds that delivers top-shelf Haze genetics in a compact, beginner-friendly package. She finishes in just 45–55 days from seed, stays between 80–100cm tall, and still pumps out the resinous, trichome-coated buds you'd expect from a proper Haze hybrid — just without the fuss of photoperiod light schedules or months of waiting.
This product comes in a single pack size of 3 feminized autoflowering seeds.

Why Siberian Haze Auto Deserves a Spot in Your Grow
Here's the thing about classic Haze strains: they're brilliant, but they test your patience. Long flowering times, stretchy growth, light sensitivity — it's a lot to manage, especially if your setup is a small tent or a balcony corner. Kalashnikov Seeds took their Siberian Haze — already a solid performer in cold climates — and crossed in ruderalis genetics to strip away the complexity without gutting the character.
The result is a plant that tops out at about a metre, grows a thick central stem, and packs on dense, sticky buds regardless of your light schedule. You don't need to flip to 12/12, you don't need to worry about light leaks, and you don't need three months of flowering. From the moment she breaks soil, you're looking at roughly 7–8 weeks total before harvest. For a Haze, that's almost absurdly fast.
What surprised us is that the autoflower version actually gained something the original didn't have: a meaningful CBD content of around 3%. That shifts the effect profile from pure cerebral rocket fuel into something more balanced — a clear-headed, uplifting onset that gradually melts into deep physical relaxation. Medicinal growers have taken notice, and we get why. The Sativa-dominant genetics (50%) still lead the charge, but that 40% Indica backbone rounds out the experience nicely.
How to Grow Siberian Haze Auto Seeds
- Germinate your seeds using the paper towel method or directly in a small pot of moist, light soil mix. Taproot should appear within 24–72 hours.
- Plant the germinated seed about 1cm deep in your final container — autos don't love transplanting, so start in the pot you intend to finish in. A 10–15 litre fabric pot works well.
- Provide 18–20 hours of light per day from seedling stage through harvest. Autos don't need a dark period to flower, so more light equals more energy for bud production.
- Keep temperatures between 20–26°C and relative humidity around 50–60% during veg, dropping to 40–50% once flowers form.
- Begin light feeding after week 2. Autos are sensitive to overfeeding — start at half the recommended dose and increase only if the plant looks hungry.
- Watch for pre-flowers around week 3–4. Once pistils appear, switch to bloom nutrients. The plant will stretch slightly but won't double in size like a photoperiod Sativa.
- Harvest when 70–80% of trichomes have turned milky with a few amber ones appearing — typically around day 45–55 from seed. The thick stem and resinous buds will tell you she's ready.
Honest Limitations — What to Watch For
No autoflower will match the yield of a well-grown photoperiod plant in the same space. The 350g/m² ceiling is achievable, but it requires solid lighting (at least 400W equivalent), proper nutrition timing, and no early stress. Stunt an auto in week one and she never fully recovers — there's no veg time to compensate.
Outdoors, the 80g per plant figure assumes warm, sunny conditions. If you're growing in northern Europe with short summers, she'll still finish (that's the beauty of autos), but expect yields closer to 40–60g in cooler climates. She handles cold better than most Haze genetics — Kalashnikov bred her for Siberian resilience, after all — but she's not frost-proof.
Compared to something like a Royal Dwarf or Quick One, Siberian Haze Auto is slightly taller and takes a few days longer. The trade-off is a noticeably better terpene profile and that balanced Sativa/Indica effect that cheaper autos simply can't deliver. If speed is your only priority, go smaller. If you want quality smoke from an auto, this is the one we'd pick.
The Smoke — What to Expect from Siberian Haze Auto
The buds come out dense but not rock-hard, coated in a visible layer of resin that makes trimming a sticky affair. Break one open and you'll get that classic Haze funk — slightly spicy, slightly sweet, with an earthy undertone from the Indica side. It's not subtle.
The effect starts upstairs: a clear, focused head-high that's social and creative without being racy or paranoid. Give it 20–30 minutes and the Indica genetics start pulling you into physical relaxation. Not couch-lock territory, but a warm heaviness that makes you want to stay exactly where you are. The 3% CBD content likely contributes to that smooth landing — you don't get the abrupt crash that pure Sativa autos sometimes deliver.
Frequently Asked Questions
How long does Siberian Haze Auto take from seed to harvest?
45–55 days total. That's from the moment the seed cracks open to the day you chop. One of the fastest Haze-dominant autos available.
Can I grow Siberian Haze Auto outdoors in a cold climate?
Yes — Kalashnikov Seeds specifically bred this line for cold tolerance. She'll finish outdoors in northern Europe, though yields will be lower than in warm, sunny conditions. Expect 40–80g per plant depending on sunlight hours and temperature.
Is Siberian Haze Auto good for beginners?
Absolutely. The autoflowering genetics remove the need to manage light schedules, and her compact 80–100cm height means she won't outgrow a small tent or balcony. Just don't overfeed her in the first two weeks.
What's the CBD content of Siberian Haze Auto?
Around 3%, which is notable for an autoflower. This gives her a more balanced effect than pure THC strains and makes her interesting for medicinal growers looking for a Sativa-leaning hybrid with some physical relief.
How tall does Siberian Haze Auto grow?
Between 80 and 100cm in most conditions. She's among the taller autoflowers but still manageable in a standard 120cm tent with room for a light above.
What yield can I expect indoors?
Up to 350g/m² under strong lighting with proper nutrition. Realistically, most growers hit 250–300g/m² on a first run. She responds well to LST (low-stress training) if you want to maximise canopy coverage.
Does Siberian Haze Auto need a specific light schedule?
No. As an autoflower, she'll flower regardless of light hours. We'd run 18/6 or 20/4 for the best balance of growth and energy savings. 24/0 works but gives the plant no rest period.
