Where Silver Haze Comes From
Silver Haze was introduced by Sensi Seeds of Amsterdam. The breeder’s goal was practical: Haze is a famously tall, slow-flowering sativa descended from Central American, South Indian and Thai lines, and crossing it with Northern Lights shortened flowering and reduced stretch while keeping the Haze character. SeedFinder lists about 75% sativa and notes the strain collected many Highlife Cup awards.
Sources describe the lineage slightly differently. Leafly lists Haze crossed with Northern Lights. SeedFinder’s family tree gives Silver Pearl (itself Early Skunk and Northern Lights #5) crossed with Haze. Leafly lists Lemon Haze and Supa Durban among its offspring. The name refers to the heavy coat of trichomes on the buds.
Silver Haze Effects: What It Feels Like
Silver Haze is known for a clear, strong cerebral high. Leafly readers most often report talkative, happy and uplifted effects, and some describe focus, with relaxation or mild sedation later in the session. Compared with a pure Haze it is described as less racy.
It works best in the daytime for conversation, walks and creative work. Because the high is potent, newer users can find it intense: headache, dizziness, anxiety and paranoia at heavy doses are all reported.
Silver Haze Terpenes, Aroma and Flavor
The aroma is earthy and woody, with peppery spice and a citrus lift, and Leafly’s flavor tags include tobacco, woody and earthy. Reviewers describe a peppery, earthy taste with a hint of citrus.
Leafly reports myrcene as the dominant terpene, followed by caryophyllene and limonene, which fits the herbal, peppery and citrus description.
- Myrcene: earthy, musky and herbal, also found in mango and hops
- Beta-caryophyllene: peppery and spicy, also found in black pepper and cloves
- Limonene: bright citrus, also found in lemon and orange peel
Terpene levels vary from grower to grower and batch to batch, so check the lab label on the package. Learn more in our guide to cannabis terpenes.

Growing Silver Haze
- Difficulty: Moderate
- Flowering: About 9–11 weeks (SeedFinder lists 65–75 days)
- Yield: High indoors; about 450–550 g per square meter reported
- Height: Plants roughly triple in height during flowering
- Environment: Indoor; benefits from good air circulation
Sensi Seeds designed Silver Haze to be easier to grow than a pure Haze, with a shorter flowering time and more compact structure. It still stretches a lot in flower, so short vegetative periods and SOG-style training suit it. Leafly lists good mold resistance, but airflow still matters in wet Pacific Northwest autumns.
Home growing is legal for adults in Oregon (up to four plants per household) but only for registered medical patients in Washington; see the Oregon and Washington law guides. Many Oregon dispensaries sell clones and seeds; see where to buy clones in Eugene.
