An independent 2026 review of Super Silver Haze, the late-90s Cannabis Cup champion bred from Skunk, Northern Lights, and Haze. The lineage, the citrus-haze profile, the heavy yield, the energetic daytime effect, and why it is an intermediate grow rather than a beginner's first plant.
Quick answer: Super Silver Haze is a sativa benchmark, a Skunk, Northern Lights, and Haze cross that swept the Cannabis Cup in the late 1990s. ILGM lists its feminized seeds at around 18 percent THC with a fast, for a Haze, 9-week flower and heavy yields up to about 9 ounces per plant indoors. The reward is a bright citrus-haze flavor and a clear, energetic daytime effect. ILGM rates it best for intermediate growers, so it is a plant to reach for once you have a grow or two behind you.
Super Silver Haze is a piece of cannabis history, not just another catalog name. It was bred in the 1990s by crossing three foundational strains: Skunk, Northern Lights, and Haze. Each parent brings something specific. Skunk contributes vigor and a pungent backbone. Northern Lights adds resin, structure, and a shorter, more stable flowering habit. Haze supplies the soaring, cerebral sativa high that made the strain famous. Put together, they produced a sativa that hits hard mentally while staying more manageable to grow than a pure Haze.
That pedigree is why the strain matters. Super Silver Haze won back-to-back High Times Cannabis Cups in the late 1990s, and it has been a reference point for sativa breeding ever since. The Northern Lights in its background is worth knowing on its own, and our Northern Lights autoflower review covers that parent, one of the most influential indicas ever bred. Because a classic this famous gets copied constantly, the seed source matters for getting a stable, true-to-type Super Silver Haze. Our full ILGM Seed Bank review covers how their catalog, shipping, and germination guarantee work.
This is the honest part of the review. ILGM rates Super Silver Haze as best suited to intermediate growers, and that rating is fair. It is not a plant we hand a complete beginner. The high yields and quality are real, but so is the sativa stretch and the need to manage height, airflow, and a longer-than-average flower. A grower with a cycle or two of experience will do well with it. A first-timer is usually better served by a more forgiving, compact strain from our best cannabis seeds for beginners guide before stepping up to a Haze.
Super Silver Haze grows tall and stretchy, the hallmark of its Haze side, and it can outgrow a short tent fast once flowering starts. Plan for the height from day one. Topping early, then running a screen or low-stress training, keeps the canopy even and turns that vertical vigor into bud sites instead of a plant jammed against the light. The buds are long and resin-coated, so a little support in late flower helps the colas carry their weight.
Feeding is moderate. Super Silver Haze responds to a steady, gradual nutrient ramp rather than heavy pushing, and reading the plant beats chasing a chart. Because it stacks resinous flowers on a big frame over a nine-week bloom, airflow through the canopy is important in late flower to keep humidity down and mold off the dense buds. Sensible defoliation opens the plant up. The core setup principles are in our Learn to Grow at Home guide.
It does best in a warm environment with room to grow. Soil brings out the fullest citrus-haze terpene expression, while coco and hydro can push slightly faster, larger plants for growers comfortable dialing in the feed. Outdoors it wants a long, warm season, which is why it thrives in Mediterranean and southern climates and is happiest indoors in cold-fall regions where an outdoor Haze would finish too late.
Yield is a major reason the strain endured. ILGM lists heavy production, up to around 9 ounces per plant indoors and up to about 10 ounces per plant outdoors under good conditions. That tall, resinous frame is what fills a tent, and canopy training under a screen is how you spread the plant and reach the top of the range rather than getting one dominant cola and a lot of larf.
Flowering runs about 9 weeks for the photoperiod line, which is genuinely fast for a Haze-dominant sativa, since pure Hazes can drag on to 12 weeks or more. The Skunk and Northern Lights genetics are what pull that timeline in. With a few weeks of veg, the full indoor cycle lands around 12 to 14 weeks from seed to harvest. Outdoors it prefers a long, warm season and finishes in mid to late fall, so northern growers, including in Michigan, get more reliable results indoors. The frost-date and season-length guidance from Penn State Extension is a useful reference for timing any outdoor crop in a cold-fall region.
Super Silver Haze is a classic daytime sativa. Users consistently report an energetic, uplifting, cerebral effect, clear-headed and creative rather than sedating, and it is often described as a productive or social strain rather than a couch-lock one. At around 18 percent THC it is not the strongest number in the catalog, but the clarity and drive of the high are what people remember. Because effects vary by person, newer users should still start with a small amount. We are not making medical claims; we are reporting what users commonly report, and any health-related use should be discussed with a qualified medical professional.
The flavor is sharp and sativa-forward. Super Silver Haze leads with bright citrus and the unmistakable haze note, over skunky, spicy, and earthy undertones from the Skunk side. It is zesty and pungent, not sweet, which sets it apart from dessert strains. That character comes largely from terpinolene and limonene. It is closest in spirit to a strain like Sour Diesel, sharp and energizing, though Super Silver Haze leans citrus-haze where Sour Diesel leans fuel. A slow cure of several weeks sharpens the citrus and smooths the skunk edge.
Grow Super Silver Haze if you want a legendary, Cup-winning sativa with a bright citrus-haze flavor, a clear energetic daytime effect, and heavy yields, and you have enough grow experience to manage a tall, stretchy plant over a nine-week flower. For an intermediate grower who wants a true sativa without a twelve-week Haze timeline, it is one of the best-balanced picks around.
Look elsewhere if this is your first grow or you have a short tent you cannot train around, in which case a compact autoflower or a bushier hybrid is a better start. If you specifically want maximum THC, a stronger hybrid like Bruce Banner tops it on paper, and if you want a sweeter, more beginner-friendly sativa lean, Blue Dream delivers similar daytime energy with an easier grow.
Super Silver Haze earned its legend and still lives up to it. It runs true to reputation: ILGM lists it around 18 percent THC with a bright citrus-haze profile, a fast-for-a-Haze 9-week flower, and heavy yields up to about 9 ounces per plant indoors. The high is the draw, clear, energetic, and creative, a daytime sativa in the truest sense. The one honest caveat is the grow. ILGM rates it for intermediate growers, so plan for the stretch and the height. For a grower ready to step past beginner strains into a real sativa classic, few plants deliver the pedigree and the payoff that Super Silver Haze does.
If you grow in Michigan, the state's adult-use law allows home cultivation within set plant limits, and Super Silver Haze's vigor makes it a strong indoor pick up north where an outdoor Haze would finish too late. Our Michigan home grow guide summarizes the rules, and the official details are on the State of Michigan Cannabis Regulatory Agency site. Always confirm your own state and local laws before planting.

Super Silver Haze is a sativa-dominant hybrid bred from Skunk, Northern Lights, and Haze. That three-way cross combines Skunk's vigor, Northern Lights' resin and structure, and Haze's soaring cerebral effect. It won multiple High Times Cannabis Cups in the late 1990s and became a benchmark sativa. ILGM lists it as a sativa-dominant classic with a citrus-haze profile.
ILGM lists Super Silver Haze feminized seeds at around 18 percent THC. That is a moderate, manageable potency by modern standards, not a chart-topping number, but the effect punches above the percentage because it is a clear, energetic sativa. The high is cerebral and uplifting rather than heavy, which is a large part of the strain's lasting reputation.
ILGM lists Super Silver Haze at about 9 weeks of flowering, which is fast for a Haze-heavy sativa, since pure Hazes can run 12 weeks or more. The Skunk and Northern Lights in its genetics shorten and stabilize the cycle. With a few weeks of veg, the full indoor run from seed to harvest lands around 12 to 14 weeks.
It is a heavy producer. ILGM lists yields up to around 9 ounces per plant indoors and up to about 10 ounces per plant outdoors under good conditions. Its tall, resinous, stretchy sativa frame is the engine. Topping and a screen to control the height and spread the canopy are how you reach the top of that range.
ILGM rates Super Silver Haze as best suited to intermediate growers. It is not the pick for a first grow. The plant stretches hard, wants managing for height, and rewards canopy training and good airflow. A grower with a cycle or two of experience handles it well, but a complete beginner is better off with a more forgiving, compact strain first.
Super Silver Haze leads with a bright citrus and classic haze character, with skunky and spicy, earthy undertones from its Skunk parent. It is a sharp, zesty, sativa-forward profile rather than a sweet or dessert one. That aroma comes largely from terpinolene and limonene. A slow cure sharpens the citrus and mellows the skunk edge.
