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.

Auto Ultimate is one of the best-yielding autoflowers in the world and, arguably, the highest-yielding autoflower in the Dutch Passion collection — a robust, vigorous plant that combines exceptional growth energy with generous harvest potential and a high-quality cerebral high. The genetics come from Dutch Passion's original photoperiod parent The Ultimate, which became a bestseller shortly after launch for combining extremely high yields with strong long-lasting effect. Auto Ultimate was created by crossing The Ultimate with the classic bestseller Auto Mazar, and the result inherited the extreme yield potential of its photoperiod parent in autoflower format. This strain has produced single-plant harvests of up to 1 kg of dry bud in expert setups, which is genuinely rare for any autoflower. The aroma mirrors the photoperiod Ultimate — dominant citrus and lime scent with sweet earthy notes developing during flowering, and after drying and curing the citrus becomes even more pronounced with strong lemon and musky character. Flavor-wise she compares to classic Lemon Haze and Lemon Skunk but with her own signature — some smokers pick up a coffee flavor on the exhale. The buds are monstrously big, most at least the size of a golf ball and completely covered in trichomes, carrying an old-school aroma reminiscent of Amsterdam coffee shop culture. Auto Ultimate is a popular strain among concentrate makers because large plants produce many sticky flowers that work equally well for cannabis oil, rosin, shatter, wax, or butter — the sheer biomass plus the terpene density makes her particularly effective as an extract base.

Big Bud Feminized is the strain Sensi built around a single dominant specification: maximum yield per square metre. An 85% indica, 15% sativa hybrid, she's prized around the world for bumper harvests — one of the main reasons the strain is a popular commercial option. The original Big Bud dates back to the 1980s US, but the War on Drugs drove breeders to bring the strain to the Netherlands, where Sensi added Skunk #1 and Northern Lights into the genetic makeup to produce the modern Big Bud: robust, skunky, and capable of impressive harvests. She took a Cannabis Cup in the Indica category shortly after entering the market. Deliciously sweet, fruity aroma with notes that users often compare to molasses, huge resin-coated buds, and a potent relaxing stone. Also available as Big Bud Regular and Big Bud Automatic for growers with different format requirements.

Black Jack is one of Sweet Seeds most powerful and productive strains, resulting from crossing Black Domina'98 with an exceptional Jack Herer.

Blueberry Bubblegum Automatic was developed by crossbreeding Gelato #420 with Sunset Sherbet to create an 80% indica, 20% sativa autoflowering cultivar. During flowering she expresses vibrant shades of green and purple, and the indica-dominant expressions result in compact plant structure with a short flowering period. The strain can be grown indoors in tents or outdoors in temperate and continental climates, which is a broader climate tolerance than many autoflowers offer. Plants produce a soothing full-body buzz paired with explosive flavor, and the low-profile growth pattern suits growers with space constraints or discretion requirements. Mario Guzman, who works under the name Sherbinski, is credited with breeding both Gelato and Sunset Sherbet — Gelato has become the backbone for many of the currently popular US-market strains, and that lineage runs directly through this autoflower.

RQS's take on the Bubblegum family, built on a Power Plant x Santa Maria cross. The Bubblegum lineage started in Indiana in the early 1990s, with phenotypes refined in New England before the Dutch cut perfected by TH Seeds put the whole line on the international map. That Dutch pedigree earned the family a 2005 High Times Cannabis Cup and a Spannabis Cannabis Champion's Cup the same year, and the candy-sweet terpene profile has kept the variety in rotation ever since. RQS's XL version pairs that Bubblegum heritage with a Power Plant backbone for a plant with the signature nose but a sturdier, more commercial structure than the original Indiana cut.

Candy Kush Express is RQS's fast-flowering answer to the long-standing "I want a Kush but not a three-month cycle" request. Genetically she is Sweet Special x Royal Kush. Sweet Special brings the candy notes — that lineage traces back through Grapefruit, Hog, and Cream Caramel, three strains that each put citrus-sweet profiles on the map in their own era. Royal Kush contributes the backbone, descending directly from the legendary Afghani Kush and carrying the indica density, resin production, and sedative potential that come with that side of the family. What makes this cross unusual is the split: 40% sativa, 60% indica is about as close to balanced as the Kush family gets, where most crosses tip hard toward knock-out indica territory. The result is a plant that tastes like candy, grows like a compact indica, and hits like a much more balanced hybrid than the name would lead you to expect.

Cherry Bacio Feminized is a 55% indica, 45% sativa balanced hybrid developed through a collaboration between Sensi Seeds' breeders and Sherbinskis, created for the Breeding Grounds program. The strain combines the potent effects of Gelato #41 with the robust stability of Sweet Cherry Kush to produce XL yields and a distinctive terpene profile. She thrives in sunny Mediterranean climates and is built around a specific terpene brief — delivering the cherry-forward flavor signature the name suggests, layered over creamy undertones and a gassy bass note that gives the experience more complexity than typical dessert-strain crosses. Well-rounded cerebral euphoria alongside a soothing body stone make her popular with connoisseurs looking for both flavor and balanced effect.

Chocolate Rainbow XXL Feminized is a 65% indica, 35% sativa hybrid developed by crossbreeding GMO with Gelato 41. The resulting plant has a slim, columnar structure with large fan leaves, bushy foliage, and spacious internodal spacing. She thrives in sunny Mediterranean climates and produces a large yield of dense buds. When consumed the strain delivers a potent body high paired with an uplifting cerebral component, and the terpene profile features distinctly sweet, creamy, fruity notes with subtle hints of diesel fuel and garlic — the garlic character traces directly to the GMO parent, which is sometimes called GMO Garlic Cookies for exactly that reason. Gelato 41 was developed by Sherbinski via a cross of Sunset Sherbet and Thin Mint GSC; GMO was created by crossing Girl Scout Cookies and Chemdawg. Both parents sit firmly in the modern US hybrid tradition.

Cookies Gelato crosses two of the most decorated modern American hybrids — Girl Scout Cookies and Gelato — and the result is a strain built for experienced smokers rather than casual sessions. Both parents are known for sweet, sugary terpene profiles and serious potency; Cookies Gelato inherits the densest expressions of each. This isn't a beginner's smoke or a low-tolerance strain: the THC is high enough that a single hit will overwhelm most novice users, and experienced smokers will recognize the pedigree immediately in the first inhale. The genetic pedigree reads like a list of the most influential US hybrids of the last decade, which is essentially what it is.

Critical is the answer to the question most commercial growers actually ask - what yields the most weight in the shortest time without sacrificing smoke quality? The genetic answer RQS landed on is Afghani x Skunk, an indica-dominant cross that compresses a classic heavy-stone Afghan profile into a plant that finishes in seven weeks. This isn't a connoisseur strain and isn't trying to be. It's a production pick built around a specific calculation: maximum grams per square meter per week, with enough potency and flavor to stand up to retail-grade expectations.

Dark Devil Auto is Sweet Seeds' hybrid between the incredible Big Devil XL Auto and an exotic autoflowering strain with purple flowers. The purple characteristic is inherited from ancestors from the Chitral region in the Pakistani Hindu Kush near Afghanistan, which contributes faster flowering while bringing sweet aromas and purple colors. Dark Devil Auto shows strong hybrid vigor from germination — plants grow with the appearance of Indica-Sativa hybrids featuring a strong central stem, numerous side branches, and a big main cola. Resin production is abundant both in flowers and surrounding leaves, and the aromatic signature combines sweet and fruity character with incense hints and delightful citrus tones.

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.

Frisian Dew is Dutch Passion's outdoor flagship — a feminised hybrid that traces its genetics to a cross between a Super Skunk female and a Purple Star male, selectively bred over many generations in Friesland, a northernmost province of the Netherlands where the Frisian language gives the strain its name. The breeding work was done by Shiva, and the result carries genuine hybrid vigor: Sativa genes drive long continuous blooms, Indica genes produce compact buds, and the combination yields one of the most consistent outdoor producers in commercial cannabis. The strain has accumulated real competition hardware — 1st place at the 2008 Highlife Cup in the Netherlands, and more recently 3rd place in the Dutch Hash category at the 2018 Homegrown Cup. She has been a cornerstone of Dutch Passion's Outdoor feminised seed collection for many years and continues to beat newer varieties at the outdoor game with relative ease. Described by users and growers as fruity, fresh, and floral, with terpene variation across phenotypes — some lean toward forest fruits and light lemon, others toward pine and lavender, and a subset express earth, ammonia, and herbal notes that show the Skunk parent influence. The unique terpene profile provides a pleasant smoking experience across the phenotypic range. Roughly 50% of plants produce purple-hued buds in the tops; there are completely green phenotypes and some plants that express pure purple from cola to calyx, and the light purple variant is a particular favorite for taste and potential among Dutch Passion's own team.

Gorilla Cookies Auto is Fast Buds' most awarded and best-selling autoflower of all time — a powerhouse fusion of GG4 Auto F6 × Cookies Auto F5 bred to deliver extreme potency, dense yields, and mouthwatering flavor in a fast easy-growing format. Now in her F6 generation, the strain has earned her reputation through real commercial and competition performance. She grows stout and bushy, reaching up to 150 cm with thick branches and a sturdy main cola. Expect golf-ball-sized buds absolutely coated in trichomes, producing up to 650 g/m² in around 10 weeks. Late in flower the buds turn almost white from resin, making her a top pick for extractors and commercial growers alike.

Gorilla Cookies FF (Fast Flowering) is Fast Buds' cross of hand-picked Girl Scout Cookies and Gorilla Glue #4 genetics combined with the famous Gorilla Cookies Auto — a variety that takes the best traits from its parents to the next level. This wonderfully balanced hybrid thrives indoors and outdoors across all climates while staying super-resilient to bugs and pests. A massive yielder offering growers of all levels up to 650 g/m² of top-shelf bud. As one of the most powerful versions of these genetics, Gorilla Cookies FF boasts a whopping 29% THC that translates into loads of resin and flavorful terpenes making for the best extractions ever — the perfect choice for hash-makers looking for hard-hitting strains producing exceptional flavors and aromas.

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.

Guava Auto transforms the growing process into an absolute pleasure — a balanced 50/50 hybrid autoflower with exceptional resilience against pests and mold, coupled with remarkable yield potential of up to 550 g/m² in just 8-9 weeks. Perfect for novice cultivators and those with busy schedules. With 28% THC content, brace yourself for a gradual yet powerful onset that seamlessly elevates mood to pure bliss. As consumption progresses, experience uplifting euphoria that enhances sociability and chattiness to unparalleled levels. In resin production Guava Auto surpasses expectations in both quality and quantity — indulge in a creamy fusion of sweet tropical guava and fruity flavors. A coveted choice for hash makers and extractors, this strain not only tantalizes taste buds but ensures substantial returns on flower-to-rosin conversions.

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.
