Auto Mazar is Dutch Passion's autoflowering version of the legendary Mazar photoperiod variety — a classic that has been in the collection for over a decade and counts among the founders of the autoflower revolution that transformed commercial cannabis breeding during the 2010s. The genetics cross the original award-winning Mazar (Afghani x Skunk #1) with an Indica-dominant autoflower, and the result is a robust, easy-to-grow plant that produces powerful Afghan Indica character with the short cycle and simplified cultivation of auto format. Auto Mazar was also the basis for Blue Auto Mazar, where it was crossed with another Dutch Passion legend, the original Blueberry, to produce the Blue Family auto line. The aromatic profile is classic Afghan Kush: earthy, spicy, pungent, with notes of lime and lemon on top — a clean old-school hash aroma sometimes slightly pine-like in haze-leaning phenotypes. The taste matches the nose — earthy Kush and lemon with a slightly pungent edge — producing authentic Afghan hashish character rather than generic auto approximation. This strain grows and flowers best under 20 hours of daily light indoors and produces potent buds that are genuinely not inferior to a photoperiod Kush variety. Dutch Passion remains proud to keep this plant in the collection after all these years — novice growers routinely achieve more than 100 g per plant, experienced growers have pushed well past that, and the current record for a single Auto Mazar plant is 900 g of dry bud. The combination of XL yields, robust genetics, and reliable Kush-character effect has made her one of the most repeatedly-grown autoflowers in the Dutch Passion catalog and one of the most appreciated outdoor strains alongside Auto Ultimate, Auto Euforia, and Auto Duck.

Black Domina Feminized is one of the darkest indica strains Sensi Seeds produces — a 95% indica four-way hybrid built for sedative potency, striking visual character, and flavor that matches the drama of the name. Sensi used four premium indica strains to create her: Northern Lights for resin production, Ortega for analgesic and soporific properties, Hash Plant for short flowering time and rich harvests, and an Afghanica called SA for strong growth and stable flower clusters. The combination produces an almost-pure indica that packs more of a punch than the sum of its parts — strongly sedative, almost narcotic, with compact growth and a short flowering cycle. Also available as Black Domina Regular for purists who prefer the original seed format.

Green Poison F1 Fast Version is Sweet Seeds' feminized, photoperiod-dependent version of the classic Green Poison featuring ultra-fast flowering — an F1 hybrid resulting from crossing the elite clone of the appreciated Green Poison with a selected 3rd Generation autoflowering genetic line of Green Poison Auto. The strain is ready to harvest with thick buds covered in abundant aromatic resin just 6 weeks after the flowering photoperiod begins, which is genuinely exceptional for a photoperiod strain. Plants display the appearance of Indica-Sativa hybrids with exceptionally vigorous growth, very fast flowering, and large flower production. The taste and aroma are exquisite, with a sweet intense hint of fruit. This strain is remarkably resistant to mold in outdoor grows — the fast flowering lets her beat the botrytis season that typically attacks traditional outdoor photoperiod strains, making her particularly valuable for humid climates where slower strains would fail.

Hash Plant Regular is a tribute to old-school cannabis — a 90% indica strain with a resinous Afghan lineage and a flowering cycle short enough to be a headline feature on its own. Average flowering time is just 45 days, the plant stays ultra-compact, and the resin content is immense, producing a mild hashish taste and the kind of strong body stone that the Hindu Kush region's hash plant traditions are built on. A multi-award-winning strain that took prizes at the Highlife Festival in 2002 and at the Copa de la Marihuana in 2004, among other recognitions. The name traces back to the Hindu Kush growing tradition: indica strains from that region are called hash plants specifically because their resin content is so heavy that harvest is followed by hand-rolling the collected resin into balls that are sold as charas. Sensi built Hash Plant Regular on a premium quality, extremely sticky Afghan strain, then tested several crosses and backcrosses with Northern Lights #1 before finalizing the line.

White Label's Master Kush Feminized is a cross between two well-known landraces from India and Afghanistan — what you get when you take some of the best pure-indica genotypes in the world and combine them into a modern feminized format. Resinous, heavy buds packed with THC and CBD, a deeply recognizable charas-like smell, and a cultivation profile simple enough that it borders on hands-off. Growers value the short flowering time and low height, which make her particularly well-suited to indoor tents or small outdoor plots, and the buds are versatile enough to be enjoyed as dried flower, kief, or home-made hashish. In 2004 Master Kush was awarded the High Life Cannabis Cup, confirming what longtime Hindu Kush fans already knew about the strain's quality. Also available as Master Kush Regular or Master Kush Automatic for alternative seed formats.

Mohan Ram is Sweet Seeds' cross of a White Widow elite clone with S.A.D. Sweet Afgani Delicious S1 — a hybrid combining the fresh, floral, fruity top notes from the White Widow side with the sweet musky character of the award-winning S.A.D. mother. The result is an ideal mostly-Indica plant with spectacular resin production and a finished smoke that layers White Widow's bright profile over the deeper Afghan dessert character. She blooms very fast, features a strong long-lasting effect, and is easy to grow with exquisite aroma throughout the cultivation cycle.

Big Devil XL Auto is Sweet Seeds' 3rd Generation autoflowering hybrid — the result of crossing Big Devil #2 Auto with an autoflowering Jack Herer from the Sweet Seeds R&D Department.

Ice Cream Haze is Dutch Passion's new-school USA-inspired F1 hybrid — a vigorous, potent Haze-dominant Sativa with 18-22% average THC (peaks up to 25%), XXL yield potential, and a terpene profile combining spicy Haze notes with sweet fruity creamy Gelato and Wedding Cake character from the Ice Cream Cake parent. Available in both feminised and regular cannabis seed formats, the strain was developed years ago by breeder Antonio (35 cannabis cups in the last 7 years) initially as regular seeds, with the feminised version released later after excellent community feedback. The Haze mother comes from a Crockett's Haze selection — a vigorous fast-growing Sativa known for exceptional yields exceeding 750 g/m², with tropical fruit-smelling sticky character and outstanding taste. The Ice Cream Cake pollinators (Gelato x Wedding Cake, both male and female) are vigorous, stable, and quick to root. The mother plant always provides compact, easy-to-cut potent buds with beautiful appearance; the father has strong aroma, powerful branches, good masculine top structure, and very frosty sugar leaves. Combining these two cultivars — one full Sativa, one slightly more Indica-dominant hybrid — creates a truly unique F1 cross suited to lovers of fast-growing plants with generous yields of strong-smelling and strong-tasting weed. The terpene profile is super penetrating and intense: powerful spicy Haze aroma with notes of tropical fruit and smooth thick ice cream. Some phenotypes smell very strongly of spicy-yet-fruity Haze; others lean toward the Ice Cream Cake parent with pungent terpene-rich Gelato genetics (originally from the Cookie Family). The real winners in every pack are plants that combine both profiles in balance — these are the phenos worth keeping and cloning. Taste leans to the Haze side of the spectrum — spicy, fresh, fruity simultaneously — with all phenotypes producing beautiful buds covered in thick trichome layers. The frosty appearance at harvest is genuinely photogenic, and Ice Cream Haze has remarkable bag appeal once dried.

Laughing Buddha is Barney's Farm's award-winning Sativa-dominant cross of Thai and Jamaican landrace genetics — an 80% Sativa / 20% Indica hybrid that combines two tropical sativa traditions into a distinctive 23% THC strain with unusually layered character. The Thai side contributes clean cerebral energy and the characteristic sweet-herbal note that defined classic Thai sticks; the Jamaican contribution adds the uplifting social euphoric quality that made Jamaican ganja legendary through the reggae era. The combination produces an aromatic profile described as fresh, sweet, exotic fruits — layered enough to stand out among modern Haze-dominant Sativas — and a palate that combines roasted pepper and pineapple top notes with lemon and herbal supporting character. The finished smoke tastes exactly like the heritage it comes from: clean, tropical, complex, and unmistakably Sativa. The effect is focused, productive, giggly, energized, creative, social, and euphoric — one of the most genuinely daytime-friendly profiles in the Barney's Farm Sativa catalog.

Shaman is a Sativa-dominant outdoor classic from Dutch Passion, built from a cross between an exceptional quality male Purple #1 and a Skunk female — a reliable, potent F1 hybrid that has been in the Dutch Passion catalog for several decades and still attracts new growers each season. Originally developed as a regular seed strain, Shaman is also available as feminised seeds, giving growers a choice of format. The original breeding program crossed an early Skunk with a colorful Purple variety, and the work was perfected when a very robust and easy-to-grow outdoor plant emerged from the selection. Sativa dominance defines the experience — the Sativa side handles growth structure, effect, and most of the aromatic character, with the small Indica proportion contributing to density and compactness where needed. Users describe the aroma as fresh, sweet, spicy, and floral, sometimes with sour notes and a pine undertone across different phenotypes. The taste is mainly sweet and spicy, with some phenotypes leaning more acidic and others expressing a piney, woody character. Green phenotypes usually taste slightly sweeter than the purple phenotype, which is worth noting for growers selecting cuts. Because of the diversity of phenotypes within the line, there's genuinely something for every palate — and for growers who run multiple plants from a single pack, pheno-hunting can reveal genuinely distinct expressions of the strain. The most striking visual trait is the purple coloration: about 50% of plants develop pink/purple tones in the flowers, ranging from light pink through rich violet to almost-black dark purple depending on phenotype and temperature. On certain phenotypes even the flower hairs go pink or purple instead of the usual orange or brown, which produces some of the most photogenic outdoor cannabis flower in the Dutch Passion lineup.

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.

Auto Cinderella Jack is Dutch Passion's answer to the question of whether an autoflower can genuinely outperform photoperiod varieties on pure potency — and the answer is a decisive yes. With a THC percentage of nearly 26% verified by two separate laboratories using the HPLC method, this is the most potent autoflower in the Dutch Passion collection and arguably the strongest autoflower in the world at launch. The strain took 2nd prize at the Copa Esmeralda in Colombia in 2018, confirming what the lab analysis already showed. The genetic lineage is (Cinderella 99 x Jack Herer) x Magnum Genetics: two legendary photoperiod parents known individually for potency, flavor, and yield, crossed with the Magnum autoflower line from Buddha Seeds (which guarantees above-average harvests and contributes the auto genetics). The project started as a Cinderella 99 x Jack Herer hybrid, with Magnum auto genetics added to convert the line to autoflower. The result comes from many generations of selective breeding focused mainly on one characteristic: THC percentage. Only careful breeding by a skilled master breeder made this level of potency achievable in autoflower format, and the breeding program used professional laboratory analysis at every stage to ensure the high-THC genetics remained stable across generations and across individual plants. The terpene profile is dominated by alpha-pinene (pine), beta-myrcene (floral, earthy, fruity), beta-caryophyllene (spicy and woody), and limonene (citrus, fresh and fruity). Combined these produce a strong pine-like, spicy, and fruity aroma with some phenotypes expressing more fruit and freshness than others. The buds are super white, loaded with trichomes, and deliver a wonderfully tasty high that hits hard and lasts long — a unique combination of cannabinoid power and terpene complexity that separates her from generic high-THC strains.

Early Skunk Feminized is Sensi Seeds' best all-rounder for outdoor cultivation, built specifically to produce bumper crops in climates that would kill lesser strains. A 35% sativa, 65% indica hybrid that won an award at the High Life Cannabis Cup in 2006, Early Skunk combines uncomplicated skunk genetics with a powerful hybrid buzz and the mould-resistance needed to finish reliably in the short, wet summers typical of Northern Europe. Robust and resilient enough to reward novice growers, she's the strain Sensi built to solve a specific problem: before this line, growing potent skunks to full maturity in places with short summers was essentially impossible. Fat skunk buds tend toward mould in poor weather, which forced northern growers to harvest before flowering peaked. Early Skunk was developed explicitly to solve that problem.

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.

Passion #1 is one of the oldest outdoor varieties in the Dutch Passion collection — a feminised hybrid cannabis strain with California origins that have been shaped by Dutch breeding work since 1980. Originally developed as one of the best green outdoor varieties in 1970s California, the strain was formerly known as Amstel Gold and is the result of years of selection and crossing. It's been bred selectively over decades for speed, size, yield, and potency, and the combination of those four traits has made Passion #1 one of the fastest and at the same time largest outdoor varieties available on the commercial market. THC levels can reach nearly 20%, which is high for an outdoor strain and particularly high for one with this growth vigor — Passion #1 is no weak outdoor option. Smokers looking for potent resin-drenched buds from a strain bred explicitly for outdoor cultivation have relatively few better picks. The aroma is fresh, tart, and slightly spicy, dominated by a fruity blend of lemon, lime, and woody herbs — rosemary and thyme come through clearly for experienced palates. The scent is strong without being super-penetrating, a practical advantage for outdoor growers who prefer not to advertise their plants to neighbors or passers-by. The taste follows the aromatic profile: sour citrus notes mixed with a bit of spice and earth, smoking smoothly and producing a strong potent up-high. The sharp, spicy, sour notes can tingle the throat on bigger draws, which some users love and others find notable.

White Label's Pure Power Plant Feminized is a fast-flowering 60% sativa, 40% indica strain built for quick turnarounds and abundant yields. She's been around since the 1990s and remains popular — a firm favourite in Dutch coffeeshops, often on the menu, and prized for super-sized yields that surpass many other cannabis strains. The strain produces a skunky vanilla-wood aroma during growth that carries through clearly into the finished flavor, and the sativa dominance results in a talkative, uplifting, exuberant high. Grown indoors or in warm outdoor climates, she delivers plentiful yields — as much as 700 grams per square metre under optimal conditions — alongside a focused, energetic effect that the 60% sativa genetics drive directly. Also available as Pure Power Plant Automatic by White Label for autoflower setups.

Royal AK Auto is the autoflowering reinterpretation of the original AK-47 hybrid — one of the most recognizable strain names in commercial cannabis. The lineage pulls from the same pool of Colombian, Mexican, Thai, and Afghan landraces that defined the AK character: hardiness, resilience, and a sweet-floral nose that set the strain apart from the heavier-indica skunks of its era. RQS's auto version adds ruderalis genetics for rapid cycle times without sacrificing the giggly, daytime-friendly effect of the original. Genetic split sits at 40% indica, 35% sativa, 25% ruderalis — an unusually balanced distribution for an autoflower, and one that preserves the AK-47 experience rather than substituting a generic auto profile for it. For growers who want AK character without the photoperiod commitment or the multi-phenotype lottery of traditional polyhybrid seed packs, this is the closest commercial match available.

Royal Cheese Auto is the autoflowering version of the legendary UK Cheese line — a strain bred in Britain for its notorious pungency and tranquil, munchy effect profile. RQS built their auto version by crossing Cheese into Royal Critical Auto, which contributed the short cycle and euphoric lift of a Cannabis Cup-winning autoflower. The result is a 50% indica, 30% sativa, 20% ruderalis split that preserves the skunky cheese aroma while cutting weeks off the timeline. For growers chasing Cheese character without the full photoperiod commitment, this is the cleanest shortcut RQS offers, and the phenotype expression stays close enough to the original UK Cheese that veteran growers recognize the lineage immediately.

Runtz x Layer Cake is Barney's Farm's cross of the widely-known Runtz genetics with Layer Cake — a balanced 50/50 Indica/Sativa hybrid that produces 28% THC in a genuinely balanced hybrid package. The Runtz side contributes the candy-sweet dessert character that made the Runtz family a modern US classic; Layer Cake brings structural density, compact bud architecture, and additional terpene complexity. The aromatic profile is tropical fruits, herbal, sweet, and spicy — a layered signature that stands out against single-line modern hybrids — and the palate delivers citrus, diesel, earthy, and spicy notes with the complex character the parent lineage suggests. The effect is creative, strong body high, uplifting, and relaxing — genuinely balanced hybrid territory where users get both cerebral energy and body relaxation in proportion.

Silver Fire Feminized is an indica/sativa hybrid with a serious genetic pedigree: Sensi's own award-winning Silver Haze crossed with the popular US strain Fire OG. Originally part of the inaugural Sensi Seeds Research project in 2019, Silver Fire proved so popular with the community that Sensi decided to add her to the permanent catalogue — despite her not being one of the final three choices from that first research round. The plants reach average heights with rapid growth during flowering, produce large yields, and carry a spicy, citrusy aroma and taste that trace back to both sides of the lineage. The high is uplifting, euphoric, and potent — a fairly powerful, fast-acting effect that novice users should be ready for, because she comes on quickly and with real intensity.
