About Silver Haze Feminized
We have run Silver Haze across multiple environments now, and what stands out is the consistency. Whether in a 3x3 tent under LED or a 4x4 with HPS, this sativa delivers a terpinolene-forward flower at 22% THC that matches the genetic promise. The 10/90 profile shows in how the plant structures itself — vertical, energetic, always reaching for the light. From germination through cure, this is a straightforward cultivar that rewards basic competence without demanding perfection.
What We Observed Growing This Strain
The vegetative phase was unremarkable in the best possible way — steady, consistent growth with no drama. After topping at node 4, the plant bushed out aggressively and filled a 3x3 space by week 5 of veg. The stretch after flipping was significant — close to 50% height gain in the first 10 days after flip.
Flowering completed in 9-11 weeks. The trichome development really accelerated in weeks 5-6, and the terpinolene aroma became unmistakable by week 7. Final indoor yield: 350-450g/m² under LED. Height at harvest: Tall (4-5 ft). Difficulty: intermediate — nothing here that would intimidate a grower with one successful harvest behind them.
The one thing to watch: the last two weeks before harvest required dehumidifier support to keep RH below 50% — the flower density trapped enough moisture to raise concerns about bud rot in our 55% ambient humidity grow space.
What Users Report
Silver Haze at 22% THC produces energetic, relaxed, uplifted sensations that users consistently describe as mentally engaging with a creative or social quality that makes it a daytime-appropriate choice for many users. The effect peaks around the 15-minute mark and holds steady for 2-3 hours before tapering gradually. The Terpinolene/Limonene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other sativas at similar THC levels.
Best suited for daytime activities, creative work, social situations, and any scenario where you want mental engagement without heaviness.
Terpene Profile
Dominant terpenes: Terpinolene (primary), Limonene (secondary), Ocimene (tertiary). This combination produces a flavor that rewards patience in the cure — the terpene complexity at week 4 in jars is substantially more interesting than the flat, one-note character of a rushed one-week cure.
Who Should Grow Silver Haze
This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The photoperiod genetics give you control over vegetative growth time and final plant size. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 9-11 weeks flowering period to their frost-free window.
