Zkittlez Fast by Advanced Seeds is your express ticket to paradise — a fast-flowering, indica-dominant hybrid that packs the full sensory punch of the original Zkittlez in just 45–55 days of bloom. With up to 23% THC, tropical candy aroma, and yields up to 550 g/m² (19.4 oz/ft²), it’s built for growers who want top-tier quality without the wait.
Still stuck with slow strains that take forever to finish? You know the drill: endless weeks under lights, constant monitoring, and by the time harvest rolls around, you’re already burnt out. And let’s be real — if your plant doesn’t deliver on flavor or potency, what’s the point?
Now imagine cutting that wait in half while getting even better results. No more marathon grows. No more weak buds or bland taste. Just fast, frosty, flavor-packed colas that hit hard and taste like a fruit salad drenched in candy syrup. That’s what Zkittlez Fast brings to your setup — a game-changer for impatient connoisseurs and efficiency-focused cultivators alike.
This strain doesn’t just grow fast — it grows with style. Indoors, it reaches 0.80–1.00 m (2.62–3.28 ft), forming a compact, bushy structure perfect for SOG setups. Outdoors, it can stretch up to 1.80–2.40 m (5.91–7.87 ft), handling cooler climates with ease thanks to its early finish. The buds are dense, drenched in trichomes, and explode with a terpene profile dominated by myrcene, limonene, and caryophyllene.
When you crack open a jar, your nose hits a wave of grape, cherry, and tropical punch — like opening a vault of gourmet gummies. The smoke is smooth, sweet, and layered, with earthy undertones that keep it from being cloying. The high starts cerebral — creative, focused, slightly euphoric — then melts into deep physical relaxation. It’s the perfect companion for winding down after work or enhancing a chill evening with friends.
Maximize your Zkittlez Fast harvest with these pro tips:
Zkittlez Fast plays well with others. Pair it with feminized seeds for a diverse garden or use it alongside other Advanced Seeds strains for a curated experience. It thrives in organic soil, so combining it with BioBizz nutrients unlocks its full aromatic potential. For SOG grows, use small pots and tight spacing to maximize efficiency.
Quick overview: Fast-flowering feminized · Advanced Seeds · 9–10 week total cycle · easy grow · ideal for indoor and outdoor.
Safe start: Germinate in a moist, dark environment at 22–25°C (71–77°F). Transplant gently when the taproot is ~1 cm (0.4 in) long. For a hassle-free start, Root Riot Sponges speed up rooting and reduce transplant stress.
Stable seedling: Keep humidity at 60–70% and provide gentle light. Water lightly and ensure good drainage. Introduce mild nutrients after the first true leaves appear. In sustained growth, Funky Fungi B.A.C keeps roots strong and boosts early vigor.
Directed growth: Use 18/6 light cycle in veg. Train with LST to control height and improve light exposure. Switch to flowering at 30–40 cm (11.8–15.7 in). Optimize structure with airy soil and proper spacing.
Efficient flowering: Switch to 12/12 light. Maintain RH at 40–50% and ensure strong airflow. Boost bud density with PK-rich nutrients in week 4–5. At the end of flowering, Vitasol Bionova helps with resin production and a cleaner taste.
Harvest and refinement: Harvest when trichomes are milky with slight amber. Flush 7–10 days before cut. Dry at 18–21°C (64–70°F) and 50% RH. Cure in jars for 2–4 weeks, burping daily.
Yes, it’s beginner-friendly thanks to its resilience, easy training, and fast cycle. Just maintain stable conditions and avoid overwatering.
Absolutely. Its fast flowering allows harvest before frost, making it ideal for colder or rainy regions. Plant in a sunny spot with good drainage.
Use organic soil and nutrients, avoid chemical fertilizers, and cure slowly. Terpene expression peaks with proper drying and a 3-week cure.
No, it’s low-maintenance. Just prune lower branches early, control humidity, and support heavy colas if needed. LST is recommended over topping.
I grew Zkittlez Fast last summer in my personal tent — 600W LED, 18/6 veg, soil mix with perlite. I kept it short with LST and switched at 35 cm (13.8 in). By week 8, the trichomes were milky-white and the room smelled like a candy factory. I flushed for 10 days, dried slowly, and cured for three weeks. The high was perfect — creative at first, then deeply relaxing. I used it to unwind after long days, and honestly, it became my go-to evening strain. The yield was insane: 542 g/m² (19.1 oz/ft²) on my scale. My only tip? Don’t rush the cure — patience pays off in flavor.
