Power Flower traces back to the 1990s, when a group of Dutch growers visiting South Africa noticed tall, vigorous native sativas growing in the wild. They brought seeds home to the Netherlands and began breeding for potency and yield, eventually landing on what became Power Plant - one of the defining commercial sativa strains of 1990s Amsterdam. Power Flower is the RQS evolution of that project, a more refined, more potent descendant of the original South African genetic base.

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.

Royal Queen Seeds' take on the Super Silver Haze lineage — Haze x Skunk x Northern Lights — a cross whose story really begins in the 1970s, when a pair of American brothers started collecting and breeding sativas from Colombia, Mexico, Thailand, and South India. After thousands of seeds and years of work they isolated the clean, soaring cerebral effect that came to define the entire Haze family. When those genetics eventually reached Amsterdam alongside the now-classic Skunk lines, two Dutch breeders set out to solve Haze's main problem: the flowering time was too long to be commercial. Crossing Haze with Skunk and Northern Lights gave them Super Silver Haze, the first Haze variety with indica-scale flowering and Cannabis Cup pedigree. Shining Silver Haze is RQS's version of that line, a two-time winner of the Highlife Cannabis Cup in the Bio Haze category and a well-respected sativa among growers who want Haze character without the commitment of a four-month bloom.

Strawberry Lemonade is Barney's Farm's cross of Strawberry with Lemon OG — a 60% Sativa / 40% Indica hybrid that produces one of the cleanest fruit-forward flavor profiles in the catalog at 24% THC. The Strawberry side contributes the berry-sweet character; Lemon OG brings the sharp citrus signature and OG Kush structural backbone. The combination produces an aromatic profile described as sweet, lemon, earthy, strawberry, and fruity hash — a layered signature that stands out in the Sativa-dominant category — and the palate delivers strawberry, lemonade, lemon, skunky, and sweet notes that reflect the name exactly. The effect is creative, calming, uplifted, happy, focused, and energetic — one of the most balanced daytime-session profiles in the Barney's catalog.

Sweet Cheese is Sweet Seeds' fusion of Cheese with Black Jack — combining two of the strongest hitters in the catalog to produce a hybrid that highlights the virtues of both ancestors. The cross brings a new twist of aromas to Black Jack's flavor foundation, producing long central buds surrounded by plenty of peripheral buds maintaining long structure and good caliber.

Tangerine Dream is Barney's Farm's triple-cross combining G13, Afghan, and Neville's A5 Haze genetics — a 60% Sativa / 40% Indica hybrid built around a complex three-way lineage that produces an extremely citrus-forward aromatic and flavor profile. The Afghan Indica contribution adds density and yield stability; the Neville's A5 Haze brings the classic Dutch Haze cerebral lift; and the G13 genetics reinforce the hybrid vigor. The result is a strain with intense citrus aroma (orange, berries, sweet on the nose) that carries through to a richly layered palate — orange, berry, citrus, sugary, tropical — producing a finished smoke that tastes exactly like the name promises. THC runs 23%, which is strong without being overwhelming, and the effect profile is body-relaxing, cerebral, euphoric, and hunger-inducing in classic Sativa-leaning hybrid fashion.

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.

Wedding Cheesecake FF (Fast Flowering) is Fast Buds' delight for mind and body — a delicious strain offering XXL yields in a 7-8 week flowering cycle. This terpene powerhouse produces loads of mouth-watering vanilla-creamy-cookie-scented terpenes with hints of citrus and cinnamon. The variety grows very well both indoors and outdoors, yielding up to 650 g/m² without extra maintenance — the ideal strain for beginners as it allows maximum yields with minimum work. This super-fast feminized photoperiod version offers upbeat and energetic yet deeply relaxing effects perfect for consumers looking for heavily focused, motivating, and creative high. With up to 25% THC, she's ideal for those needing an extra energy boost to start a busy day on the right foot.

Fast Buds' Z-Up Auto is a sativa-leaning autoflower born from the fusion of the RS-11 cut and Auto Z F5, bringing an entirely new citrus-forward terpene profile to the table. The F5 edition is bright, loud, and full of energy, designed for daytime use, flavor hunters, and fans of all things fizzy and uplifting.

Ztrawberriez Auto is a Fast Buds next-generation polyhybrid bred from Strawberry Pie Auto, Z Auto, and Tropicana Cookies Auto — delivering up to 25% potency, yields of 600 g/m², and award-winning flavor in just 9-10 weeks. Winner of Best Sativa at the American Autoflower Cup 2024, she's a flavor-chaser's dream with a complex blend of fruity terpenes, rock-solid buds, and a perfectly balanced hybrid effect.
