Crystal Candy Auto by Sweet Seeds – Sweet Fruity Aroma & Fast 8-Week Harvest

Crystal Candy Auto by Sweet Seeds is a fast, high-yielding autoflower that packs a sweet, fruity punch in just 8 weeks from seed to harvest, making it perfect for quick-turnaround grows with serious flavor and resin production.

Worried your autoflowers won’t deliver big yields or complex flavors? Too many 'fast' strains end up small, bland, or weak—leaving you stuck in a cycle of underwhelming harvests and wasted time. You want something that actually lives up to the hype: fast and flavorful, easy and potent.

Crystal Candy Auto shuts that doubt down. Bred from elite Sweet Seeds genetics, it grows tall, produces dense, crystal-coated buds, and floods your space with a mouthwatering aroma of strawberry gum and ripe melon—all in a reliable 8-week cycle. No more compromises.

Why Crystal Candy Auto delivers where others fail

This isn’t just another compact auto. At 0.70–1.30 m (2.30–4.27 ft), it’s built for volume. With up to 600 g/m² indoors and 300 g per plant outdoors, it outperforms most autos in its class. The 60% Indica dominance brings structure and resilience, while the 38.4% Sativa adds vigor and a balanced high. It’s the rare auto that feels like a photoperiod in yield and presence.

Common doubts, clear answers

Let’s clear the air on what really matters:

How to grow Crystal Candy Auto successfully

Maximize your harvest with these simple, proven steps:

1. Start with a 3–5 L pot and move to 18–20 L early — autos hate root disturbance.
2. Provide 18–20 hours of light daily — no photoperiod switching needed.
3. Use well-aerated soil or coco — ensure good drainage to prevent overwatering.
4. Water when the top inch feels dry — avoid soggy roots.
5. Feed lightly; increase nutrients gradually — autos are sensitive to overfeeding.
6. Apply HESI Hydro Growth in early veg for strong root and leaf development.
7. Support branches if needed — large buds can get heavy.
8. Flush 7–10 days before harvest — improves taste and smoothness.

Personal Experience of Pevgrow’s CEO (Alan)

I was skeptical at first—another 'candy-flavored' auto? But Crystal Candy Auto surprised me. I grew it side-by-side with a photoperiod, and it kept up in height and yield. The smell during flowering was unreal: like walking into a sweet shop. I used Bud Factor X in mid-flower, and the resin production went through the roof. Harvested in week 8, cured for 3 weeks—smooth, flavorful, and perfectly balanced. It’s now one of my go-to recs for growers who want quality without the wait.
