Sweet Mandarine Zkittlez F1 Fast Version by Sweet Seeds – Fast-Flowering Feminized Hybrid

Sweet Mandarine Zkittlez F1 Fast Version by Sweet Seeds is a photoperiod-dependent, feminized hybrid that finishes flowering in just 7 weeks, delivering potent, aromatic buds with a vibrant citrus-diesel profile and energizing effects.

Stuck in slow-growth mode?

Waiting 10, 11, even 12 weeks for your plants to finish flowering? That’s time you could be harvesting, enjoying, or starting your next grow. Long cycles mean more electricity, more risk of mold, and more stress if your schedule’s tight.

What if you could cut that wait in half — not with an auto, but with a photoperiod that gives you full control and still finishes in record time? That’s the frustration this strain was built to erase.

Sweet Mandarine Zkittlez F1 Fast Version is your shortcut to quality. With a flowering time of just 7 weeks, it’s perfect for impatient growers, seasonal outdoor setups, or anyone who wants more harvests per year. You get the control of a photoperiod with the speed of an F1 hybrid — dense, resinous buds ready fast, without sacrificing potency or flavor.

Before you plant Sweet Mandarine Zkittlez F1 Fast Version

Get ready for a fast ride. This strain doesn’t mess around, so your setup needs to be tight from day one. Whether you're growing indoors under LEDs or outdoors in a sunny spot, make sure your environment is stable before germination.

• Start with a clean, sterile germination setup
• Use pots of 18–20 L (4.76–5.28 gal) for indoor photoperiod grows
• Choose well-aerated soil or coco for optimal root development
• Set your light cycle to 18/6 during vegetative growth
• Check pH levels: aim for 6.0–6.5 in soil, 5.8–6.2 in coco

During the grow: speed with stability

From seedling to harvest, this strain moves fast but stays strong. You’ll notice vigorous growth early on, with tight internodal spacing and a bushy structure that responds well to LST. The citrus-pine aroma develops quickly, so consider a carbon filter if discretion is key.

It thrives in temperate to continental climates and shows solid resistance to cold and mold — a big plus for outdoor growers in shorter seasons. Feed it consistently, but avoid overloading in flowering; this plant values balance over brute force.

For sustained growth, Medi One organic fertiliser for growth and flowering | Green Planet Nutrients keeps leaves green and structure compact without excess nitrogen.

After harvest: flavor, effects, and maintenance

Once cured, expect a complex smoke: sweet mandarin and mango up front, backed by spicy diesel and a woody-pine finish. Some phenotypes show beautiful purple and reddish hues by the end of flowering — a visual treat as much as a sensory one.

The effect? Uplifting, creative, and social — perfect for daytime use when you want to stay sharp but inspired. THC levels range from 19–24%, so it’s not for beginners, but the ride is smooth and clear-headed.

After your harvest, clean your space thoroughly. This strain doesn’t demand special upkeep, but a well-maintained environment ensures your next grow is just as fast and flawless.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Sweet Mandarine Zkittlez F1 Fast Version in my 1.50 x 1.50 m (4.92 x 4.92 ft) tent under a TS-3000 LED, and it was a game-changer. I started with 3 plants in 20 L pots, soil-based, and used SensiZym Advanced Nutrients from week 2 to boost root activity and nutrient uptake.

The stretch was minimal — maybe 30% — and by week 3 of flower, the trichomes were already glistening. I flushed for 10 days, dried slowly at 19 °C (66.2 °F) and 55% RH, and cured in glass jars. The result? Frosty, dense buds with a zesty, diesel-citrus punch that hits your nose before you even open the jar.

The high is clean and motivating — I used it while working on new product designs, and it kept me focused without anxiety. At 24% THC, it’s strong, but never overwhelming. If you want speed, potency, and flavor in one package, this is it.
