Amnesia Zkittlez Auto Cannabis Seeds by FastBuds
Amnesia Zkittlez Auto is a 75% sativa-dominant autoflowering cannabis seed that crosses old-school Dutch Amnesia genetics with the candy-sweet Zkittlez line from California. FastBuds bred this one to deliver coffeeshop-grade bud in just 9–10 weeks from germination — no light schedule changes, no fuss. The result is a fast, vigorous plant with a terpene profile that smells like a fruit bowl left next to a bag of classic Haze.
Why Grow Amnesia Zkittlez Auto Seeds
Two of the most celebrated gene pools in cannabis, combined in a single autoflowering seed — that's the pitch, and it actually delivers. Amnesia has been a coffeeshop menu staple in Amsterdam for decades, prized for its soaring, cerebral sativa effect and sharp Haze terpenes. Zkittlez brought something completely different from the US West Coast: dense, resinous buds with a grape-candy sweetness that took dispensary shelves by storm. FastBuds crossed the two and added ruderalis genetics to make the whole thing automatic.
What you get is a plant that doesn't need a 12/12 light flip to start flowering. She'll veg for roughly 3–4 weeks, stretch a bit as she transitions, then stack heavy flowers for the remaining weeks. The autoflowering format means you can run her under 18–20 hours of light from start to finish indoors, or plant her outdoors in any month where temperatures stay warm. Total lifecycle: approximately 9–10 weeks from the moment the seed cracks.
We'd pick this strain over a standard photoperiod Amnesia if speed matters to you. You sacrifice a bit of the ceiling yield you'd get from a full-size photo plant, but you gain weeks of time and a much simpler grow process. For a first autoflower grow, this is a strong choice — the genetics are stable, the growth pattern is predictable, and the end product genuinely impresses.
Amnesia Zkittlez Auto Grow Guide
FastBuds rates this strain as straightforward to grow, and from what we've seen, that checks out. Here's how to get the most from your seeds.
- Germinate using the paper towel method or directly in a small pot of lightly moistened seedling soil. Taproots typically appear within 24–72 hours.
- Transplant seedlings into their final container early — autoflowers don't love root disturbance mid-grow. A 10–15 litre fabric pot works well indoors.
- Provide 18–20 hours of light daily throughout the entire cycle. LED or HPS both work. She's not fussy about spectrum, but she does respond well to strong light intensity during flowering.
- Feed lightly during the first 2–3 weeks, then ramp up nitrogen during veg and switch to a bloom-heavy feed once you see the first pistils forming.
- Watch the stretch. Amnesia Zkittlez Auto can reach up to 120cm, and the main cola gets heavy. A bamboo stake or plant yo-yo will save you from a snapped stem in late flower.
- Monitor humidity closely once buds fatten up. Her dense flower structure traps moisture — keep relative humidity below 50% in the final weeks to avoid mould.
- Harvest when trichomes shift from clear to milky-white with a few amber heads. This typically falls around week 9–10 from germination.

Aroma and Terpene Profile
This is where Amnesia Zkittlez Auto really earns its name. Crack open a cured jar and you get an immediate hit of sweet, grapey fruit — that's the Zkittlez parent doing its thing. Underneath, there's the unmistakable sharp, spicy Haze funk that anyone who's walked through an Amsterdam coffeeshop will recognise instantly. It's a layered smell: candy on top, incense and citrus peel underneath, with a slightly earthy base note that rounds it all out.
The terpene profile leans heavily on fruity and floral compounds. According to Healthline, terpenes like beta-caryophyllene, humulene, and myrcene — commonly found in Haze-lineage strains — have been the subject of research into their potential physiological interactions (Healthline, "Best Cannabis Strains for Sex"). We're not making claims about what this specific strain does — just noting that the terpene family it belongs to has attracted scientific interest.
When smoked or vaped, the flavour follows the nose: a sweet, almost tropical inhale with a peppery, Haze-forward exhale. It's genuinely one of the tastier autoflower profiles we've come across. If you've grown standard Amnesia before and wished it had more sweetness, this is your answer.
Amnesia Zkittlez Auto vs Other FastBuds Strains
FastBuds has a deep catalogue, so it helps to know where Amnesia Zkittlez Auto sits relative to a couple of other popular picks.
| Strain | Phenotype | Harvest Time | Indoor Yield | Character |
|---|---|---|---|---|
| Amnesia Zkittlez Auto | 75% Sativa | 9–10 weeks | Up to 600g/m² | Fruity Haze, cerebral, soaring sativa |
| Fat Bastard Auto | 50% Indica / 50% Sativa | 9–10 weeks | High | Balanced hybrid, dense buds, heavy resin |
| Gorilla Cookies Auto | Indica-dominant | 9–10 weeks | Up to 600g/m² | Relaxing, cookie dough terps, couch-lock |
If you want a headier, more uplifting sativa experience, Amnesia Zkittlez Auto is the clear pick from this lineup. Fat Bastard Auto splits the difference between body and head, while Gorilla Cookies leans much more towards physical relaxation. We'd point you towards Amnesia Zkittlez Auto specifically if you prefer daytime-oriented strains with complex terpene profiles.
Honest Limitations — What to Watch Out For
No strain is flawless, and Amnesia Zkittlez Auto has a couple of things worth knowing before you commit. First, her pest and pathogen resistance is only moderate. If you're growing outdoors in a humid climate, you'll need to stay on top of inspections — those dense buds are magnets for botrytis (bud rot) if moisture gets trapped inside. Indoors, keep your airflow strong and your humidity in check during the last 2–3 weeks of flower.
Second, this strain prefers warm to hot conditions. If you're in Northern Europe trying to grow her outdoors, you'll want to time your plant for the warmest months or consider a greenhouse. She's not the most forgiving auto in cold, damp weather.
Third — and this is more of a heads-up than a flaw — the sativa dominance means the high can be intense for people with low tolerance. For anxiety-prone users, smaller, spaced doses are recommended to capture mood elevation without triggering overstimulation, according to FastBuds' own strain notes. Start slow with the finished product.
Growing Amnesia Zkittlez Auto indoors? Pair your seeds with a complete grow tent kit to control temperature, humidity, and light from day one. A carbon filter is non-negotiable once those fruity Haze terps start filling the room — your neighbours will notice. If you're after a different flavour profile to run alongside this one, Gorilla Cookies Auto makes a solid companion grow with a contrasting indica-leaning character.
