Studio 54 Stardust Auto® by Sweet Seeds – Fruity Autoflower with 25% THC & Colorful Buds

Studio 54 Stardust Auto® by Sweet Seeds is a high-THC autoflowering strain that delivers colorful, resin-rich buds with a sweet tropical punch in just eight weeks from seed to harvest.

Still stuck with bland, low-yielding autos?

Most autoflowering strains promise fast results but leave you with weak flavors, pale buds, and mediocre potency. You end up with harvests that lack character — forgettable smoke that doesn’t spark joy or creativity.

What if your auto could actually impress?

Imagine opening your drying rack to find buds bursting with color — deep purples, fiery reds — coated in crystal trichomes and oozing with banana-mango aroma. No more settling for average. No more wasting months on slow photoperiods just to get flavor and power.

How to grow Studio 54 Stardust Auto® – expert grow guide

Optimized for speed, flavor, and color — this autoflower rewards simplicity.

Safe start

• Germinate in moist paper towels or starter cubes at 22–25 °C.
• Transplant gently once the taproot reaches ~1 cm (0.4 in).
• Use a light, airy soil mix to prevent damping off.
• For faster rooting, Kit Hesi Starterbox Soil provides balanced nutrients and root support.

Directed growth

• Maintain 18–20 hours of light daily — no photoperiod switch needed.
• Water when topsoil feels dry; avoid overwatering in early stages.
• Transplant to a 20 L (5.28 gal) final pot by day 17 to maximize yield.
• Apply Vita Star Plagron to boost root development and early vigor.

Efficient flowering

• Expect pre-flowers by week 3; full flowering by week 4.
• Keep humidity at 40–50% to prevent mold, especially as buds swell.
• Support branches if needed — dense buds can get heavy.
• Use Plagron Power Buds in mid-flower to enhance resin and bud density.

Harvest & refinement

• Harvest at 8 weeks when trichomes turn milky to slightly amber for balanced effect.
• Flush with plain water 7–10 days before harvest to improve taste.
• Dry slowly at 18–22 °C (64.4–71.6 °F) and 50–60% RH for 10–14 days.
• Cure in jars for 2–4 weeks, burping daily, to develop flavor and smoothness.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autos, but Studio 54 Stardust Auto® stood out immediately. I planted it alongside some photoperiods last spring, and by week 8, it was ready while the others were still in mid-flower. The aroma hit me first — pure mango and banana, like a fruit stand in a California summer. The buds were dense, frosty, and some turned a deep, wine-like purple. I made some rosin from it, and the color? Unbelievable — golden amber with purple streaks. The high is clean, creative, and lasts. Not too heavy, not too spacey — just right for daytime inspiration. If you want an auto that doesn’t compromise, this is it. I’d recommend it to anyone tired of boring, fast-grown weed.
