Cinderella Auto 420 Fast Buds by FastBuds – Sativa-Dominant Autoflower with Tropical Peach & Pineapple Flavor

Cinderella Auto by FastBuds is a high-performing sativa-dominant autoflower that delivers up to 550 g/m² of dense, trichome-covered buds with a mouthwatering tropical flavor of ripe peach and pineapple, all in just 8–9 weeks from seed to harvest.

Struggling to find a strain that’s both powerful and beginner-friendly? One that grows tall without taking over your space, hits hard without locking you to the couch, and tastes like a vacation in every puff? Too many autos fall short—either weak, finicky, or smelling like a skunk convention. You want quality without the headache.

It’s frustrating when your plant stretches too much, gets moldy in humidity, or just doesn’t deliver on flavor and yield. You’ve probably tried strains that promised big but left you with airy buds and a flat high. Or worse—snapped branches under heavy colas because they weren’t built to handle their own success.

Meet Cinderella Auto: the upgraded version of the legendary Cinderella 99, now in a fast, forgiving autoflower. With a 65% sativa dominance, it gives you a racy cerebral high that boosts focus and creativity, then gently melts into a relaxed, floating state—no couch lock. It grows up to 1.20 m (3.94 ft) with a strong central stem and thick side branches, producing up to 550 g/m² (19.41 oz/ft²) indoors and 160 g (5.65 oz) per plant outdoors. The buds are dark green, dense, and absolutely drenched in trichomes, giving off a sweet, tropical aroma with hints of pine and skunk. It’s resilient, easy to grow, and perfect for SCROG or LST—no green thumb required.

How to grow Cinderella Auto: expert tips

Get the most out of your grow with these pro-backed recommendations—simple, effective, and tailored to this strain’s strengths.

Safe start: Germinate seeds in a moist paper towel at 22–25 °C. Transplant carefully once the taproot is ~1 cm long.

• Use a well-aerated, light soil mix for seedlings
• Keep humidity at 60–70% in early stages
• Apply RootFast by Atami to boost root development
• Avoid overwatering—let topsoil dry slightly between waterings
• Start with low light intensity to prevent stretching

Directed growth: Maintain 18–20 hours of light daily. Train early with LST to control height and maximize canopy.

• Move to final 20 L pot early to avoid root stress
• Use organic nutrients for best flavor and terpene expression
• Begin light defoliation to improve airflow
• Support side branches with soft ties as they gain weight
• Keep pH at 6.0–6.5 (soil) or 5.8–6.2 (coco)

Efficient flowering: Monitor trichomes—harvest when mostly milky with some amber for balanced effects.

• Reduce humidity to 40–50% to prevent mold
• Boost flowering with Super PK Aptus during weeks 4–6
• Flush 7–10 days before harvest for cleaner taste
• Use stakes or netting to support heavy colas
• Ensure strong airflow to avoid bud rot

Personal Experience of Pevgrow’s CEO (Alan)

I first grew Cinderella Auto when I was looking for a sativa that wouldn’t take six months and wouldn’t snap under its own weight. What I got was a game-changer. It grew to 1.15 m (3.77 ft) in my 2.5 ft tent—tight, bushy, and loaded with frosty colas. I used a simple 18/6 light cycle, organic soil, and just a touch of bloom booster. No topping, no FIM—just LST and trust in the genetics. The high hit fast: clear-headed, energetic, perfect for writing or hiking. After a couple of hours, it mellowed into a smooth, floating relaxation—never sedating. The flavor? Like biting into a ripe peach with a hint of pine. I’ve recommended it to friends who are just starting, and even my veteran grower buddy used it for a quick-turn rosin run. It’s one of those rare strains that’s easy for newbies but respected by experts. If you want a sativa that actually delivers, this is it.
