Super Silver Haze Feminized – Nirvana Seeds · High THC, Citrus Aroma & Massive Yields

Super Silver Haze feminized from Nirvana Seeds is a legendary sativa-dominant hybrid that delivers up to 24% THC, electrifying cerebral effects, and citrus-drenched buds covered in silver trichomes—perfect for creative energy and social moments.

Are you chasing weak highs and bland flavors?

Many sativas promise sky-high energy but leave you anxious, unfocused, or underwhelmed with flavor. Others stretch out of control, wasting space and light. And if you're after serious potency, most just don’t deliver.

What happens if you keep settling for average strains?

You’ll waste precious grow cycles on plants that overgrow your tent, collapse under their own weight, or produce bland, low-THC buds. You’ll miss out on that legendary Haze clarity—where every puff fuels focus, laughter, and inspiration. Worse, you might end up with harsh smoke that ruins the experience.

Super Silver Haze gives you the original Amsterdam powerhouse—reliable, resinous, and ready to elevate

This High Times Cup winner combines Skunk #1, Northern Lights, and Haze to deliver a clean, long-lasting high with massive yields and a flavor that pops from first light to last hit. It’s not just potent—it’s poetic.

Feel the creative spark without the crash

Forget jittery sativas that burn you out. Super Silver Haze lifts your mood, sharpens focus, and keeps the energy smooth and social. Whether you're writing, hiking, or vibing with friends, this strain keeps the momentum going for 5–6 hours without anxiety or sedation. The citrus-terpene rush clears your head and brightens your world—naturally.

How to grow Super Silver Haze for maximum resin and yield

Start strong with healthy seeds and a solid plan. This sativa thrives when you guide her growth early and support her during flowering. Keep it simple, stay consistent, and let her shine.

1. Germinate seeds in a moist paper towel or starter cube at 22–25 °C and high humidity.
2. Transplant to a well-draining soil or coco mix once roots appear (~1 cm); use 11–20 L pots for photoperiod control.
3. Use an 18/6 light cycle in veg and switch to 12/12 to trigger flowering after 4–6 weeks.
4. Apply LST (Low Stress Training) early to control height and expose more bud sites to light.
5. Support heavy branches with bamboo stakes from week 4 of flowering to prevent breakage.
6. Avoid overwatering and overfeeding—this strain shows nutrient burn easily, especially in coco.
7. Harvest when trichomes are mostly cloudy (for energetic effect) or amber (for relaxation), around 9–10 weeks.

Why Super Silver Haze stands out from the rest

• Thanks to its Haze x Skunk x Northern Lights genetics, it grows tall and vigorous, which means you can train it for a bushier canopy and bigger harvests.
• With THC levels reaching 24%, you get a powerful, long-lasting high that fuels creativity and conversation without overwhelming anxiety.
• Its intense citrus and floral terpene profile delivers a refreshing, eye-watering aroma that lingers on the palate and enhances the entire experience.
• Indoors, it produces up to 600 g/m² (2 oz/ft²), making it a top choice for growers who want commercial-grade yields from a classic sativa.
• Outdoors, it can reach 1.80–2.00 m (5.91–6.56 ft) and deliver up to 1200 g (42.3 oz) per plant in sunny, Mediterranean-like climates.
• The frosty, trichome-rich buds are perfect for extractions—hash, rosin, or RSO—giving you more value from every gram.
• Its balanced hybrid nature offers both mental uplift and mild body relaxation, making it ideal for daytime use without couch-lock.

Care, maintenance and storage tips

After harvest, dry buds slowly at 18–20 °C and 50–60% humidity to preserve terpenes. Cure in glass jars for 2–4 weeks, opening daily to release moisture. Store final product in airtight containers away from light and heat to maintain potency and flavor. During growth, ensure good airflow to prevent mold, especially in humid environments.

• Use a carbon filter if growing indoors to manage the strong citrus-skunk aroma.
• Flush plants 7–10 days before harvest to improve taste and smoothness.
• Monitor pH levels: 6.0–6.5 in soil, 5.8–6.2 in coco or hydro.
• Keep humidity at 40–50% during flowering to reduce mold risk.
• Remove lower, shaded leaves to improve airflow and focus energy on top colas.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Super Silver Haze in my 5x5 tent under a 600W HPS and trained it with LST to keep it under 120 cm. The stretch was intense—doubled in height in the first two weeks of flowering—so I had to tie down branches early. By week 6, the trichomes were already stacking up like snow. I flushed for 10 days, dried slowly, and cured for three weeks. The high is unmatched: clear, fast, and motivating. Perfect for writing or long sessions with friends. Not for beginners, but if you're ready for a challenge, this strain rewards effort with flavor, resin, and legacy.
