Amnesia Haze came out of the 1990s as one of the strains that would define Dutch coffeeshop menus, and like a lot of Haze-dominant varieties her provenance is half history, half legend. What's documented is the competition record - she took 2nd place in the Highlife Cannabis Cup Bio Haze category, and demand for her has stayed high enough that RQS continues stocking seeds of the line three decades later. She's a true Haze-dominant hybrid: the kind of strain the word sativa was invented to describe, genetically and experientially.

Amnesia Haze Auto is the autoflowering solution to the biggest practical problem with the original Amnesia strain: flower time. The classic Amnesia, bred in the Netherlands in the 1990s by Hy-Pro Seeds - and known variously as Amnesia, Champagne Haze, The Bomb, and Ultra Haze - needs 11-12 weeks of bloom on average, with some phenos stretching to a full 20 weeks before finishing. That timeline is unworkable for most home growers and commercially impractical. Crossing the original into ruderalis solved it, producing an auto version that keeps the signature euphoric high and spicy-sweet flavor while cutting the cycle dramatically and limiting final height.

Early Pearl Regular is one of the foundational outdoor sativas in Sensi Seeds' catalog — a 75% sativa, 25% indica strain that was the first sativa-dominant variety developed specifically to thrive in shorter, cooler summers rather than the warm Mediterranean conditions most sativas need. First introduced in the 1980s, she's been a favorite outdoor variety ever since, and her genetics add stability and strength to future hybrids — which is why she's a popular breeding base for growers working on new crosses. Yields on outdoor plants can reach up to 2 kilograms each in the right conditions, making her one of the highest-producing outdoor sativas commercially available. Plants can grow to towering heights, sometimes reaching 4 metres when cultivated outside, with a distinctive scent of orange and pine layered over notes of incense. The high is buoyant, uplifting, and exuberant — pure classic sativa expression.

Liberty Haze is Barney's Farm's balanced Sativa-dominant hybrid combining G13 genetics with ChemDawg 91 — a cross that produces a 60% Sativa / 40% Indica split with a musky, earthy, skunky aromatic signature grounded in the Chem lineage and a cleaner pine and lime flavor profile on the palate. The herbal backbone is unmistakable, and the combination of two heavy-hitting parents produces serious THC: this strain averages 26%, which puts her at the top of Barney's Farm's catalog for raw cannabinoid content. The effect profile is long-lasting, calming, with tingly giggly euphoric character that eventually transitions to creative cerebral energy — the hybrid balance genuinely comes through in use, with neither pure Sativa racing nor pure Indica sedation dominating the experience.

Utopia Haze is Barney's Farm's heritage Sativa — a 90% Sativa / 10% Indica cross built from Brazilian landrace genetics that produces one of the purest Sativa-dominant expressions in the catalog. THC averages 22%, which is strong for a Sativa-heavy landrace-derived strain, and the Brazilian landrace foundation gives the finished smoke depth and character that modern quick-cross Sativas can't replicate. The aromatic profile is fruity, woody, pungent, and earthy — a complex landrace signature that holds up through cure — and the palate combines fruity, spicy, mint, and citrus notes in layered complexity. The effect profile reflects the near-pure Sativa character: cerebral lift, hazy relaxation, and an eventual sleepy transition at higher doses. This is unusual for a 90% Sativa — most strains this Sativa-dominant produce pure up-energy without the Indica-style sleep transition, but the Brazilian landrace heritage adds a relaxing undertone that eventually lands users toward rest rather than wired energy.

Fast Buds' Gorilla Auto is the most infamous strain in the catalog — a knockout artist with a staggering 24% THC, large plant size, and buds so loaded with resin that the "glue" in her name becomes literal: fingers will stick together during trim. She's a super-easy grow with a pine and diesel terpene profile that impresses even experienced cannabis connoisseurs, and the 9-week cycle produces enormous sticky fat buds that any type of grower will fall in love with. Well suited for beginner growers, and hash makers should not miss out on this trichome queen.

Fast Buds' Girl Scout Cookies Auto is one of their best-selling and most renowned strains — a 20% THC cultivar with extra-large yields and the fantastic sought-after cookie flavor that made the GSC family famous. The Cali cookie genetics are a cinch to grow indoors or out, producing dense sparkling nugs. A huge-yielding sticky resin machine.

Jack Herer Feminized is Sensi Seeds' tribute to the cannabis activist the strain is named after, and it lives up to its namesake reputation — officially recognized as one of the few medicinal cannabis strains in the Netherlands, and widely regarded as the prime example of an ultra-potent hybrid with dense resin production and high THC content. The hybrid split is a balanced 50% sativa, 50% indica, and the strain was developed specifically for indoor cultivation. Jack Herer has won just about every cannabis award available across multiple decades, and it's Sensi Seeds founder Ben Dronkers' all-time favorite strain — context that matters for a breeder with Ben's catalog depth.

Titan F1 is RQS's flagship entry into F1 hybrid autoflowering genetics - a new breeding category that crosses two stable inbred lines to produce uniform, high-vigor offspring with predictable traits across every seed. The parental lines for Titan share heritage with Blue Dream, Sugar Magnolia, and Amnesia, which gives her an unusual mix of fruit-forward terpenes and the kind of structural resilience commercial growers actually need. As one of the first true F1 autoflowers on the market, she's aimed at growers who want uniformity and predictability from seed rather than the phenotypic lottery of traditional polyhybrid autoflower packs.

White Label's White Widow Regular is the budget-tier interpretation of one of Amsterdam's most recognizable hybrids — 65% indica, 35% sativa, and still a coffeeshop mainstay nearly a quarter century after the original release. The strain gets its name from the thick layer of white trichomes that coats mature buds, a feature that signals the dense THC content underneath. Compact plants, high yield potential, and a genetic line that traces back thousands of years make White Widow a strain that has survived every fashion cycle in cannabis genetics since the 1990s. White Label's version preserves the core genetics while prioritizing accessibility — easy to grow, resistant to temperature fluctuations, and forgiving enough that newcomers growing cannabis for the first time can run her without catastrophe.
