Last QC test date: 2026-04-11

Outdoor yield: 635-980 g/plant (avg across 8 verified grower reports)

About Super Silver Haze Feminised

Germination & Early Veg (Days 1-14): Super Silver Haze seeds typically crack within 48 hours using the damp paper towel method and break soil by around day 3. Early growth was rapid and upright โ€” narrow first leaves reaching eagerly towards the light from day one. By the end of week two, five nodes were visible with noticeable spacing between each, signalling the sativa-dominant growth pattern ahead. Damping off is uncommon at around 70% relative humidity during this phase.

Vegetative Growth (Weeks 3-6): Vertical growth demanded attention. Even with low-stress training started in week 3, this plant wanted to climb. We bent the main stem at a 90-degree angle in week 4 and the secondary branches quickly caught up, creating a naturally flat canopy by week 6.

Flower (Weeks 1-11): This is where the 6/94 genetics of Super Silver Haze truly revealed itself. The terpinolene aroma appeared in week 3 of flower and intensified steadily. Trichome coverage became visually striking from week 5 onward. Final indoor yield: up to 800 g/m2. THC testing at 25%. Difficulty rating: intermediate.

Continuing the Grow Diary

Mid-Flower (Weeks 4-6): The transformation accelerated dramatically. Bud sites that were wispy clusters at week 3 swelled into properly defined colas. The elongated bud structure continued developing lengthwise, with fresh calyxes stacking along the main stems. Interestingly, the secondary branches produced proportionally larger buds than expected โ€” the open structure allowed light to reach lower sites that a bushier plant would have shaded out entirely.

Late Flower and Ripening (Weeks 9-11): Nutrient input dropped to plain water with a splash of molasses for the final 10 days. The terpinolene aroma became powerful enough that carbon filtration was essential โ€” our neighbours would have noticed otherwise. Trichomes progressed from clear to milky across the final fortnight, with amber heads appearing on sugar leaves first. A common harvest window is around 15% amber on the calyxes.

Dry and Cure (Post-Harvest): Whole-plant hang dry in a darkened room at 17ยฐC and 58% humidity for 12 days. Stems snapped cleanly rather than bending, confirming the moisture content was appropriate for jarring. After 4 weeks of glass jar curing with twice-daily burping (first 2 weeks) then daily burping (weeks 3-4), the bouquet fully developed. Final weight confirmed the up to 800 g/m2 yield estimate. The limonene secondary terpene became far more pronounced after curing than it was at harvest โ€” a reminder that the drying and curing process genuinely creates flavour rather than merely preserving it.

Flowering: 10-11 weeks. Indoor yield: up to 800 g/m2. Outdoor yield: 1500 g/plant. Rated intermediate difficulty. Feminised seeds.

What to Expect When Using Super Silver Haze

New Zealand users report focused, energetic, calm as the defining characteristics, and our experience aligns with that consensus. At 25% THC, this sativa sits in a potency bracket where most users find a productive sweet spot. Vaporised at 175-185ยฐC, the initial effect is a noticeable uplift in mood and mental energy that pairs well with creative projects, bushwalks, or social barbecues. The body remains light and mobile throughout, making this a genuine daytime option for those with THC tolerance. The Terpinolene/Limonene terpene combination imparts a flavour that lingers on the palate โ€” complex and shifting, revealing new notes across the session.

Ideal settings: creative pursuits, social gatherings, outdoor adventures, and daytime leisure.

Terpene Breakdown

Primary: Terpinolene ยท Secondary: Limonene ยท Tertiary: Ocimene. Flavour translation from flower to vapour and smoke differs with this terpene combination. Low-temperature vaporisation (180-188ยฐC) highlights the limonene and ocimene notes whilst keeping terpinolene as a foundation. Higher temperatures or combustion flatten the profile into a single-note experience โ€” still pleasant, but lacking the complexity that makes this cultivar genuinely interesting to those who appreciate flavour.

Suitability and Recommendations

Super Silver Haze suits growers with fundamental skills already established. You should understand pH management, basic nutrient ratios, and light cycle requirements before committing to this cultivar โ€” it will not hold your hand, but it will not punish minor mistakes harshly either. Photoperiod genetics give you complete control over plant size and harvest timing โ€” extend the vegetative phase for larger plants or flip early for a quicker turnaround in compact spaces. The New Zealand growing season (October through April) accommodates the 10-11 weeks bloom period comfortably for outdoor growers in the warmer northern regions. Shipped discreetly within New Zealand with sourced grow figures on every strain page.
