Amnesi-K Haze Cannabis Seeds by Kannabia
Amnesi-K Haze is a sativa-dominant feminised cannabis seed bred by Kannabia that recreates the legendary Amnesia Haze from a unique combination of Jamaican, Laotian, Afghan, and Hawaiian landraces. She flowers in just 9–10 weeks — remarkably fast for any Haze variety — and delivers tall, trichome-coated colas with a citrus-forward aroma that old-school Dutch coffeeshop regulars will recognise instantly.
We've carried Kannabia seeds for years and this one consistently gets people talking. The genetics behind Amnesi-K Haze aren't your standard Amnesia cross — four distinct landrace lines give her a complexity you don't often find in modern hybrids. If you've grown Haze varieties before and got frustrated by 14-week flowering times, this is the one that finally respects your schedule.
Pack Size
Amnesi-K Haze is available in packs of 5 feminised seeds. Every seed is female — no males to cull, no wasted pots.

Growing indoors? Amnesi-K Haze stretches hard in bloom, so a grow tent with at least 1.8m of vertical clearance is worth considering. Pair her with a carbon filter setup — those citrus terps are gorgeous but your neighbours might not appreciate them as much as you do.
Why Amnesi-K Haze Deserves a Spot in Your Garden
The original Amnesia Haze has been a coffeeshop staple in Amsterdam for decades. Walk into any shop on the Warmoesstraat and you'll find it on the menu, usually near the top. The problem? Classic Amnesia Haze genetics can be painfully slow — 12 to 14 weeks of flowering isn't unusual, and that's a long time to wait when you're managing a grow room with limited cycles per year.
Kannabia's breeders tackled that head-on. By crossing four landrace varieties — Jamaican, Laotian, Afghan, and Hawaiian — they've pulled the flowering time down to 9–10 weeks without gutting the sativa character that makes Amnesia Haze worth growing in the first place. That's 3–4 weeks saved per cycle. Over a year of indoor growing, that extra cycle adds up significantly.
The honest limitation: this is still a proper sativa. She stretches hard once you flip to 12/12 — we're talking plants that can double in height during bloom. If your indoor ceiling is tight, you need to plan for it. Topping or FIMming during veg is basically mandatory indoors unless you've got a tall tent. Outdoors in a warm climate, she'll happily reach 2 metres and fill out with long, dense flower clusters. She's not the most beginner-friendly plant in the catalogue — if you've never grown a sativa before, something shorter and more forgiving like a Northern Lights cross might be a gentler introduction. But if you've got one or two grows under your belt, Amnesi-K Haze rewards the effort.
Growing Amnesi-K Haze: What to Expect
Amnesi-K Haze grows with classic sativa architecture — a tall central stem, relatively few side branches, and bright green foliage. She's not bushy. Think vertical, not wide. That apical dominance means she'll put most of her energy into one main cola unless you intervene with training techniques.
Outdoors, she thrives in warm, humid conditions — think southern Spain, southern France, or anywhere with a proper Mediterranean summer. Her natural pest and pathogen resistance is a genuine advantage here. We've seen growers in northern climates struggle with sativas that can't handle the damp, but Amnesi-K Haze holds up better than most.
Indoors, the stretch is the thing to manage. Flip to 12/12 when your plants are no more than half the final height you want — she'll fill the rest. A SCROG net works well to spread out those long branches and get even light distribution across the canopy. After 9–10 weeks of flowering, you'll be looking at long, slightly spongy buds in vivid green, dusted with a thick layer of trichomes and threaded with bright orange pistils. They look the part.
Aroma and Flavour Profile of Amnesi-K Haze
Crack open a cured jar of Amnesi-K Haze and the first thing that hits you is fresh citrus — sharp, bright, almost like lemon zest grated over something sweet. Underneath that top note, there's a delicate floral layer that rounds it out. On the inhale, those citrus tones carry through cleanly. On the exhale, you'll catch something earthier — a subtle spice that reminds you this plant has Afghan genetics in the mix.
If you've smoked Amnesia Haze in a Dutch coffeeshop, you'll recognise the family resemblance immediately. The Kannabia version leans a touch more citrus-forward than some Amnesia cuts we've tried, which we actually prefer. It's a terpene profile that fills a room — during the last 2–3 weeks of flower, your grow space will smell unmistakably of ripe citrus and fresh herbs.
How to Grow Amnesi-K Haze
- Germinate your feminised seeds using the paper towel method or directly in a starter plug. Keep temperatures between 22–26°C for best germination rates.
- Transplant seedlings into their final pots once they've developed 2–3 sets of true leaves. A 15–20 litre pot gives plenty of root space for this tall variety.
- During vegetative growth, top or FIM once the plant has 4–5 nodes. This breaks apical dominance and encourages multiple cola sites — critical for managing height indoors.
- If growing indoors, flip to 12/12 when plants reach roughly 40–50% of your available vertical space. Amnesi-K Haze will stretch significantly during the first 3 weeks of bloom.
- Consider a SCROG net set at canopy height to spread branches evenly and maximise light penetration across all bud sites.
- Maintain warm temperatures (22–28°C) and moderate humidity (40–50% in flower) throughout the bloom phase. Good airflow helps prevent any moisture-related issues in those dense colas.
- Harvest after 9–10 weeks of flowering when trichomes show a mix of milky and amber under magnification. Dry slowly in a dark room at 18–20°C for 7–10 days, then cure in glass jars for at least 2 weeks.
Amnesi-K Haze vs Other Amnesia Strains
There are dozens of Amnesia crosses on the market, so here's how Kannabia's version stacks up against two popular alternatives.
| Strain | Flowering Time | Height | Genetics | Difficulty |
|---|---|---|---|---|
| Amnesi-K Haze (Kannabia) | 9–10 weeks | Up to 2m | 4 landraces (Jamaican, Laotian, Afghan, Hawaiian) | Intermediate |
| Classic Amnesia Haze | 12–14 weeks | Up to 2.5m | Thai, Afghani, Jamaican, Hawaiian | Advanced |
| Amnesia Auto | 10–11 weeks seed to harvest | 80–120cm | Amnesia x Ruderalis | Beginner |
The sweet spot for Amnesi-K Haze is clear: you get the sativa character and classic Amnesia terpene profile without the punishing 14-week wait. Autoflower versions are easier and faster, but they sacrifice the height, yield, and flavour depth that make Amnesia genetics worth growing. If you want the real thing on a reasonable timeline, Amnesi-K Haze is the best Amnesia variant for growers who value both quality and efficiency.
Frequently Asked Questions
What does Amnesi-K Haze taste like?
Fresh citrus dominates — sharp lemon zest with a sweet edge. Underneath, you'll find floral undertones and a subtle earthy spice on the exhale from the Afghan genetics. It's recognisably Amnesia but with a stronger citrus lean than many classic cuts.
How tall does Amnesi-K Haze grow indoors?
Without training, she can easily reach 1.5–2 metres indoors. She stretches significantly during early bloom, so topping or FIMming during veg and flipping to 12/12 early are both recommended. A SCROG net helps manage the height effectively.
Is Amnesi-K Haze suitable for beginner growers?
She's best suited to intermediate growers. The main challenge is managing her sativa stretch indoors — without topping or training, she'll outgrow most tents. If you've completed one or two successful grows, you'll handle her fine. Complete beginners might prefer a shorter indica-dominant strain first.
What climate does Amnesi-K Haze need outdoors?
Warm and humid — Mediterranean climates are spot on. Southern Spain, southern France, Italy, or Greece all work well. She has good natural resistance to pests and pathogens, which helps in outdoor environments. Northern European climates with short, damp summers are risky for any sativa this tall.
How long does Amnesi-K Haze take to flower?
9–10 weeks from the flip to 12/12. That's remarkably fast for a Haze variety — most classic Amnesia cuts take 12–14 weeks. This shorter flowering time is one of the key advantages Kannabia bred into this strain.
What training techniques work best for Amnesi-K Haze?
Topping or FIMming at the 4th–5th node breaks her strong apical dominance and creates multiple cola sites. A SCROG net evens out the canopy. LST (low stress training) also works if you prefer a gentler approach. The goal is always the same: control height and spread light evenly.
Are Amnesi-K Haze seeds feminised?
Yes, all seeds in the pack are feminised. Every seed will produce a female plant — no need to identify and remove males. You get 5 feminised seeds per pack.
