Auto Zkittlez Cannabis Seeds by Advanced Seeds
Auto Zkittlez is an autoflowering cannabis seed from Advanced Seeds that delivers sweet, tropical buds in just 55–60 days from germination. A cross of Zkittlez and ruderalis genetics, this compact cultivar stays under 1 metre tall yet pumps out up to 550g/m² indoors — serious numbers for an auto. With around 20% THC and a terpene profile that genuinely smells like a bag of fruit sweets, she's one of the tastiest autos we've come across.
What's in the Pack
This listing contains 3 feminised autoflowering seeds. Every seed is female — no need to sex your plants or worry about pollination.

Complete your Auto Zkittlez grow with a propagation kit to nail germination, and a grow tent with carbon filter if you're running indoors — that tropical fruit aroma is loud, and your housemates (or neighbours) will notice. A basic LST clip set is also worth grabbing if you want to push yields closer to that 550g/m² ceiling.
Why Auto Zkittlez Seeds Deserve a Spot in Your Grow Room
We've sold a lot of autoflowering seeds over the years, and the ones that keep coming back into conversation share two things: they're genuinely easy to grow, and the end product actually tastes good. Auto Zkittlez ticks both boxes. The Zkittlez parent brings that unmistakable sweet, tropical fruit profile — think ripe mango and berry with a candy-like finish — while the ruderalis genetics strip away the complexity of photoperiod light schedules. You plant her, keep her fed and watered, and 55–60 days later you're trimming sticky, fragrant buds.
The honest limitation? She's compact. Under 1 metre means you're not going to get massive individual plants. But that's actually the point. You can fit more plants per square metre, and the canopy stays manageable without a ladder. For indoor growers working with a tent — say an 80x80 or 100x100 — this is a genuine advantage. Outdoor growers in northern Europe will appreciate the short lifecycle too: start her in late spring and you're harvesting before autumn rains set in.
Compared to something like Auto Gelato or Auto Gorilla Glue, Auto Zkittlez leans more towards flavour and smoothness than raw potency. The 20% THC is nothing to scoff at, but the terpene profile is the real star here. If you've been growing autos that taste like hay and disappointment, this one will remind you why you started growing in the first place. The smoke is smooth, the vapour is sweet, and the effect settles into a warm body relaxation with a clear, uplifted headspace — best enjoyed when you've got nowhere to be.
How to Grow Auto Zkittlez Seeds
- Germinate your Auto Zkittlez seeds using the paper towel method or directly in a small pot of moist, light soil mix. Keep temperatures between 22–26°C. Taproots typically appear within 24–72 hours.
- Transplant seedlings into their final container early — autos don't love being repotted mid-grow. A 10–15 litre fabric pot with well-aerated soil works well. She'll stay under 1 metre, so you don't need anything enormous.
- Provide 18–20 hours of light per day throughout the entire lifecycle. Unlike photoperiod strains, Auto Zkittlez doesn't need a light schedule change to trigger flowering — she'll do that on her own around week 3–4.
- Feed lightly during the seedling stage and increase nutrients gradually as she enters vegetative growth. Switch to bloom nutrients once you see the first pistils forming. Auto Zkittlez isn't a heavy feeder, so err on the side of less rather than more.
- If you want to push yields towards that 500–550g/m² mark, apply low-stress training (LST) during weeks 2–4. Gently bend the main stem sideways and secure it with plant ties. This opens up the canopy and encourages more even bud development. Don't top or high-stress train — autos don't have time to recover.
- Monitor humidity: keep it around 60–65% during veg and drop to 40–50% during flowering to prevent mould. Good airflow is critical with dense, resinous buds like these.
- Harvest around day 55–60 from germination. Check trichomes with a jeweller's loupe — you're looking for mostly milky with a few amber for that balanced body-and-mind effect. Dry in a dark room at 18–20°C with 55–60% humidity for 7–10 days, then cure in glass jars for at least 2 weeks.
Aroma, Flavour, and Effect — What to Expect from Auto Zkittlez
This is where Auto Zkittlez really earns her keep. Crack open a cured jar and the first thing that hits you is a wave of tropical fruit sweetness — it's not subtle. There's ripe berry, a citrus tang, and something almost candy-like underneath. It smells, honestly, like the sweets she's named after. That aroma carries over into the smoke and vapour without losing anything in translation, which isn't always the case with autos.
The effect sits at around 20% THC, landing as a warm, full-body relaxation that doesn't glue you to the sofa immediately but definitely nudges you in that direction. There's a gentle mental uplift at the onset — a brightening of mood — before the physical calm takes over. It's the kind of smoke you reach for on a Friday evening when the week's been long and you want to properly unwind. Not a daytime strain, not a party strain. A "put your phone down and enjoy the quiet" strain.
One thing we'd flag: because the terpene profile is so aromatic, you absolutely need a carbon filter if you're growing indoors. We've had customers tell us they could smell Auto Zkittlez through a closed door during late flowering. Plan accordingly.
Frequently Asked Questions
How long does Auto Zkittlez take from seed to harvest?
55–60 days from germination. That's the full lifecycle — no separate veg and flower periods to manage. She starts flowering automatically around week 3–4 regardless of your light schedule.
What yield can I expect from Auto Zkittlez indoors?
Advanced Seeds lists indoor yields at 500–550g/m². You'll get closer to the higher end with LST and proper lighting (at least 400W equivalent). Without training, expect something nearer 400–450g/m².
Can I grow Auto Zkittlez outdoors?
Yes. She does well outdoors in most European climates thanks to the short 55–60 day lifecycle. Plant after the last frost and you'll harvest before autumn humidity becomes a problem. She stays under 1 metre, so she's discreet too.
Do I need to change the light cycle for Auto Zkittlez?
No. Autoflowering genetics mean she'll flower on her own timeline regardless of light hours. Most growers run 18/6 or 20/4 from start to finish for the best balance of growth and energy cost.
Is Auto Zkittlez suitable for first-time growers?
Absolutely — she's one of the more forgiving autos we carry. No light schedule changes, compact size, and a fast turnaround mean fewer things to get wrong. Just don't overfeed her and you'll be fine.
Should I use LST on Auto Zkittlez?
We'd recommend it if you want to maximise yield. Start bending the main stem gently around week 2–3 and secure with soft ties. Avoid topping or FIM — autos don't have the recovery time that photoperiod plants do.
How does Auto Zkittlez compare to the photoperiod version?
The auto version sacrifices some yield potential and overall size for speed and simplicity. Flavour and effect are very close to the original Zkittlez, though the photoperiod version can produce larger individual plants with longer veg times. If time and ease matter more than maximum yield, go auto.
