The History and Heritage of Greenhouse Seeds: Innovation and Awards

The story of Greenhouse Seeds began in the 1980s with Arjan Roskam, who traveled the world collecting rare landraces. This valuable genetic material formed the foundation for breeding numerous legendary strains. In 1992, Arjan opened the first Greenhouse Coffeeshop in Amsterdam, which quickly became a central hub for the international cannabis scene and served as a platform for introducing his new genetics. Greenhouse Seeds has since evolved into a global empire known for its breeding innovations. The seed bank has significantly contributed to the development and popularization of feminized seeds and was among the first to focus intensely on autoflowering genetics. A standout feature of Greenhouse Seeds' work is the incredible number of awards they have won – over 40 High Times Cannabis Cups and 17 Highlife Cups are an impressive testament to the consistent quality and potency of their strains. The "Strain Hunters" project, initiated by Arjan and his late partner Franco Loja, further underscores Greenhouse Seeds' commitment to preserving cannabis genetic diversity and seeking out new, exciting strains worldwide.

The Greenhouse Seeds Assortment: Legendary Strains and Variety for Every Grower

The range of Greenhouse Seeds is the result of decades of intensive breeding work, offering an exceptional variety of cannabis seeds. The catalog includes an extensive selection of feminized seeds as well as a wide array of autoflowering seeds. Many of Greenhouse Seeds' strains have become true icons in the cannabis world. Names like Super Lemon Haze, a multi-award-winning sativa with an intense citrus aroma and uplifting effect, or White Widow, a stable hybrid known for its resin production and strong effect, are just a few of the highlights. Other popular strains like Amnesia Haze, Neville's Haze, or Great White Shark are also part of their proven offering. Greenhouse Seeds is also known for developing strains with very high THC content, which deliver a correspondingly powerful effect. In addition to these photoperiodic favorites, the seed bank offers a solid selection of autoflowering strains, allowing growers to cultivate popular genetics in a faster and more straightforward cycle. Autoflower variants of classics like Super Lemon Haze Auto or White Widow Auto are available, delivering the usual quality in a shorter time. The spectrum of genetics offered ranges from potent indicas to stimulating sativas and balanced hybrids, all bearing the characteristic stamp of Greenhouse Seeds: quality, potency, and a pronounced terpene profile.

Cultivating with Greenhouse Seeds: Reliability and Top-Quality Buds

Growing with cannabis seeds from Greenhouse Seeds is a rewarding experience for many growers, yielding high-quality buds. Thanks to decades of breeding experience and meticulous selection, the genetics are generally very stable and robust. This leads to vigorous and uniform plant growth, making them relatively easy to handle, even for less experienced growers. The feminized seeds ensure a high probability that all plants will be female, making cultivation more efficient and focusing on bud production. Greenhouse Seeds' strains are designed to perform well both indoors and outdoors. While the yield potential for many strains is considered good to very good, Greenhouse Seeds consistently focuses on the quality of the final product: dense, resinous buds with intense aroma and the strain-specific, often very potent effect. The autoflowering strains offer the added benefit of a fast life cycle, often completed from germination to harvest in just a few weeks. This is particularly practical for growers who desire quick results or cultivate under specific conditions.
