Cinderella Auto 420 Fast Buds – Fast-Growing Sativa-Dominant Auto with Tropical Flavor

Cinderella Auto by FastBuds is a high-performing, sativa-dominant autoflower that delivers up to 550 g/m² of dense, trichome-rich buds with a tropical punch of pineapple and peach—perfect for growers who want big returns without the wait.

Are you stuck with weak, flavorless buds and endless grow cycles?

Most autos sacrifice taste and power for speed, leaving you with bland smoke and underwhelming effects. You spend weeks nurturing plants only to harvest airy, leafy nugs that barely spark a buzz. It’s frustrating, time-consuming, and a total waste of space and nutrients.

And if you're chasing that classic sativa energy—creative, uplifting, social—but hate how tall and finicky those strains usually are, you’ve probably given up. Limited space, fear of mold, or just tired of high-maintenance grows? You’re not alone.

Enter Cinderella Auto: the fast, compact powerhouse that brings back the glory of old-school sativas—without the stress. She grows up to 1.20 m (3.94 ft) with a strong central stem and thick side branches, but stays tight thanks to her 35% indica genes. No more bending lights or pruning like crazy. Just plant, feed, and watch her shine.

Before growing Cinderella Auto

Prepping for a new grow? You’ll want to keep things simple but effective. This auto thrives in a stable environment with consistent light and good airflow. Whether you're setting up indoors or outdoors, start with quality soil and a pot that gives roots room to breathe.

• Use 18–27 L pots early to avoid transplant stress
• Start with a light, well-aerated soil mix or coco
• Set your light cycle to 18/6 or 20/4 for steady growth
• Keep humidity at 60–70% in seedling stage
• Pair with Kit Top Grow Box Soil for a complete, balanced start

During the grow: watch her rise and shine

Cinderella Auto stretches fast in the first few weeks, so give her space—she can hit 1.20 m (3.94 ft) tall. But don’t worry, her structure is strong, and she branches heavily, creating multiple colas that rival the main bud. Feed her steadily, but avoid overdoing nitrogen in flowering.

Her dark green buds swell with trichomes, and by week 6, that sweet tropical aroma starts to fill the room. If growing outdoors, she loves warm, sunny climates but handles moderate rain thanks to solid mold resistance. Use LST gently if needed—she responds well without stress.

For maximum resin and flavor, consider adding bloom boosters in mid-flower. Try-Pack Kit Fertilizers BioBizz Bio 100% enhances terpene production naturally, making your harvest taste even juicier.

After harvest: flavor, effect, and next steps

After 8–9 weeks, you’ll be looking at up to 550 g/m² of frosty, aromatic bud. Dry slowly at 18–20 °C (64–68 °F) and 50–60% RH, then cure for 2–4 weeks to unlock the full peach-pineapple punch. The high? A racy cerebral rush that lifts your mood, fuels creativity, and keeps you social—without locking you to the couch.

Once you’ve enjoyed your harvest, clean your space and save some seeds for next time. Or try another top performer like 420 Fast Buds Autoflowering Seeds for more award-winning genetics.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Cinderella Auto in my 1.2 m² (13 ft²) tent with 6 plants in 20 L pots. I used a 600W LED on a 20/4 schedule and started with Plagron soil. By week 4, she was stretching hard—up to 1.10 m (3.61 ft)—so I did light LST to spread the canopy.

I added BioBizz Try-Pack from week 3 onward, and the terpene boost was insane. At harvest, I got 512 g/m²—dense, sticky buds that smelled like fresh fruit candy.

The high hit fast: a sharp, happy buzz that kept me productive all afternoon. After a few hours, it mellowed into a calm, clear relaxation. No paranoia, no couch-lock—just pure, clean joy. I’ve already ordered more seeds. This one’s a keeper.
