Spliff Seeds

Established in 1995 in Amsterdam, Netherlands, Spliff Seeds was founded by a passionate team of Dutch growers and breeding veterans with a mission to stabilize premium cannabis genetics for growers worldwide. Operating out of the world’s most celebrated cannabis capital during the peak of the 1990s coffeshop boom, the brand focused heavily on rigorous mother-plant selection, genetic uniformity, and high germination viability. Spliff Seeds approaches plant breeding with classic Dutch precision. Every strain in their catalog undergoes extensive multi-generational testing to ensure strong mold resistance, structural vigor, and consistent growth traits across both indoor and outdoor setups. Their genetic archive blends heritage Afghan, South American, and Southeast Asian landraces with iconic European hybrids to deliver heavy-yielding plants rich in cannabinoids and distinct aromatic profiles. Their time-tested catalog features famous bestsellers and award-winning strains such as Spliff's Strawberry, Blue Berry, Dutch Chili, Gold Rush Outdoor, Super Skunk, Amnesia Flash, and Bubblegun.

Strain Hunters

Launched in 2008 in Amsterdam, Netherlands, Strain Hunters was created by Green House Seed Co. founder Arjan Roskam and his iconic breeding partner, the late Franco Loja. Born out of their internationally acclaimed documentary series documenting expeditions to remote corners of the world—from Africa and the West Indies to the Himalayas—the brand was established with a mission to identify, document, and preserve rare landrace cannabis genetics before habitat loss and industrial hybridizations wiped them out. Strain Hunters bridges ancient landrace botany with cutting-edge European breeding. By cross-pollinating pristine, site-specific landraces gathered during their global expeditions with stabilized European cup-winners, the breeding collective creates unique hybrids that feature extreme structural resilience, complex cannabinoid profiles, and exotic terpene profiles ranging from spicy landrace hash to sweet tropical fruit. Their globally recognized catalog features celebrated bestsellers and award-winning hybrids such as Money Maker, Afgooey, Damnesia, Flowerbomb Kush, Kaboam, and Skunk Auto. Offering feminized photoperiod strains, rapid autoflowers, and specialized medicinal profiles, Strain Hunters remains an iconic fixture in international cannabis preservation and high-potency breeding.

Super CBDx Seeds

Founded with a singular mission to revolutionize therapeutic cannabis, Super CBDx Seeds is a specialized seed bank dedicated entirely to high-cannabidiol (CBD) and low-tetrahydrocannabinol (THC) genetic research. Recognized for breaking away from high-potency recreational breeding trends, the brand set out to produce high-performing plants that deliver robust medicinal benefits without inducing strong psychoactive effects. Super CBDx achieved a major breeding breakthrough by stabilizing a foundation mother plant (Super CBDx) that consistently yields extremely high CBD percentages alongside negligible THC levels (frequently reaching CBD-to-THC ratios of 24:1 or higher). By crossing this proprietary high-CBD foundation with iconic global cultivars, Super CBDx created a catalog of high-CBD varieties that retain the specific terpene profiles, resin production, and growth vigor of famous classic strains. Their recognized catalog includes therapeutic high-CBD adaptations of world-famous genetics such as Super CBDx, Super CBDx x Jack Herer, Super CBDx x Black Widow, Super CBDx x Chronic, and Super CBDx x Critical Mass. Offering stable photoperiod feminized seeds designed for consistent cannabinoid ratios, Super CBDx Seeds remains a trusted benchmark for medical patients, wellness cultivators, and holistic extractors globally.

Founded in Amsterdam in 1985 by Karel Schelfhout and Nevil Schoenmakers (the founder of The Seed Bank of Holland), Super Sativa Seed Club (SSSC) stands as the second-oldest cannabis seed bank in history. Awarded a High Times Hall of Fame honor, SSSC played a critical role in establishing modern European seed distribution, distributing legendary genetics to over 40 countries during the 1980s via their iconic mail-order magazine catalogs. After taking a sabbatical to preserve their genetic library, Karel Schelfhout—alongside his son Kees—revived SSSC in partnership with Dutch Passion. SSSC’s core philosophy remains anchored in preserving authentic old-school breeding stock while stabilizing high-grade modern sativa-dominant, hybrid, and auto-flowering varieties designed for exceptional trichome density and complex terpene profiles. Their world-renowned catalog features legendary classics, high-potency cup winners, and modern flagship strains such as Karel's Haze, Frosty Friday, TNT Trichome, Kees' Old School Haze, Auto Bruce Lemon Paddy, and Lava Freeze.

TGA Genetics

Founded in the United States in 2001 by the late, legendary breeder Subcool (Monty Caverhill) alongside his former partner MzJill, TGA Genetics (The Green Avengers) is one of the most influential and respected names in American cannabis history. Operating under a revolutionary "open-source genetics" philosophy, Subcool and the TGA team shared their breeding knowledge, parent lineages, and organic cultivation methods openly with the global growing community. TGA Genetics became world-famous for its strict adherence to producing non-feminized, high-potency regular seeds. Subcool’s breeding framework relied on a small pool of legendary mother plants—most notably the fruit-and-sour Space Queen male (known as "Space Dude") and Pluton—crossed with elite clones like Jack's Cleaner, Chernobyl, and Romulan. TGA strains are celebrated for their exceptional resin density, high THCV production, and distinct complex terpene profiles ranging from lemon-cleaner, cherry, and tropical fruit to sour fuel and rotting fruit. Following a devastating California wildfire in 2017 that destroyed Subcool’s primary collection, the brand briefly rebranded as Subcool's The Dank before Subcool’s tragic passing in 2020. TGA’s genetic legacy remains globally celebrated through iconic hallmarks such as Jack the Ripper, Space Queen, Chernobyl, Vortex, Querkle, Agent Orange, JTR, and Pennywise. TGA Genetics remains the definitive gold standard for regular seed collectors, organic soil growers, and craft breeders worldwide.
