STRNG Seeds – Purple Punch Auto

Purple Punch Auto captures the full dessert-like personality of the original photoperiod version, but with the added benefit of speed and compact growth. It offers the same eye-catching purple tones and sweet, fruity flavor in a format that’s perfect for growers who want fast, fuss-free results.

As the plant matures, it releases a layered aroma of grape candy, blueberry yogurt, and soft vanilla, with a subtle herbal undertone. It’s a fragrance that becomes more complex as the flowers fatten and ripen.

Most describe it as a strain with a gentle, calming nature. It tends to be well-suited for moments of unwinding and relaxing.

Very closely. The structure is smaller, but the taste, aroma, and visual appeal hold up remarkably well. You’ll still get dense purple buds, sugary trichomes, and that signature grape-and-berry flavor with every cycle.

Indoors, it usually stays within 60–90 cm, while outdoors it may stretch up to 100–110 cm. Its compact size and bushy structure make it ideal for tight spaces or discreet outdoor spots.

Very important — especially when growing in coco or hydro. Keep pH levels around 5.8–6.2 for hydro/coco and 6.3–6.8 for soil to maintain healthy nutrient uptake.

Growers who value flavor and aesthetics love this strain. It’s also great for those who appreciate mellow, reflective moments without intensity or overstimulation.

Not at all. It’s generally low-maintenance and resilient, thriving in a range of conditions with minimal intervention. This makes it a smart choice for new growers or anyone seeking reliability.

Yes — under the right conditions, Purple Punch Auto develops deep violet and lavender hues in the buds and sugar leaves, especially when exposed to cooler nighttime temps late in flower.

On average, expect a full cycle of 9–10 weeks from germination. Some phenos may go a little longer, but most finish quickly without sacrificing yield or bag appeal.

No. As an autoflower, it will transition to flowering on its own. You can keep lights on 18–20 hours per day from start to finish for strong growth and better yields.

Yes, as long as there’s no frost. It’s a solid choice for short-season regions because of its quick turnaround, and its compact frame makes it easier to shelter or protect if needed.

Absolutely. Its small stature, low noise (odor), and short lifecycle make it ideal for stealth grows on balconies, patios, or private gardens.

Yes. In mild climates, growers often complete 2–3 cycles between spring and fall thanks to the strain’s short seed-to-harvest time.

It can handle light LST (low-stress training), especially early in veg. However, more aggressive methods like topping are not recommended due to its short lifecycle.

Use final containers from the beginning to avoid transplant stress. 3–5 gallon (11–19L) pots give the roots enough room while supporting the compact plant size autos are known for.

Cooler temperatures late in the flowering phase (especially at night) can trigger the purple pigments in the buds and leaves. Keep nighttime temps 5–10°C lower than daytime for best results.

Go easy. Autos generally don’t like strong feeding early on. Start with half-strength nutrients and gradually increase during flowering if the plant responds well.

Keep relative humidity between 45–50% during flowering to minimize risk of mold in the dense buds. Good airflow is essential, especially in indoor setups.

Look for clouded trichomes and fading pistils. Buds will feel firm and sticky, and the sweet, grape-heavy aroma will be at its peak just before harvest.
