Silver Haze®
The first Haze is vintage masterpiece of cannabis breeding - a harmonious blend of complementary equatorial genotypes that’s widely regarded as the purest and most powerful Sativa ever created. Sensi’s award-winning Silver Haze distils the sunny cerebral magic of her towering parent into a manageable strain with great indoor potential
Haze started out as a multiple-Sativa hybrid with roots in Central America, South India and Thailand. Developed in the days before indoor growing and cultivated below 30°N, her breeders were not restricted by factors like height, yield or short summers. As indoor growing gained popularity in the Eighties, true Haze began to disappear. Though smokers still adored the soaring high, growers found her slow flowering, low yields and unstoppable height-gain impractical for indoor production.
Silver Haze was the first seed strain to offer a solution by delivering the full-strength Haze experience in a fatter, faster, more compact form. Together with NL#5xHaze (her taller sister), Silver Haze helped reverse the decline of the psychedelic Sativa. As soon as such frosted, pleasingly dense tropical crops could be produced efficiently with lights, ganja lovers all across the globe were able to sample that supreme high and the Haze cult rapidly spread far beyond its original circle of devotees.
The original Haze has had both its outrageous height gain and interminable flowering period brought under control by breeding with an extra-potent, non-dominant individual from the Northern Lights line. The dark Afghanica also throws its weight behind the feathery Sativa budding pattern, adding bulk without affecting flower formation.Silver Haze should still be expected to triple her vegetated height in flowering, so seedlings and clones may be flowered almost immediately in close-cultivation methods like SOG.
Silver Haze buds are composed of long, silky pistils sprouting from oval calyxes which surge along the stem and branches to fill the gaps between internodes. Afghani influence is seen in the strain’s thick layers of silver resin glands and the way her calyxes swell, adding density in the final weeks of flowering.

SENSI SEEDS PIONEERED THE CANNABIS INDUSTRY TO BECOME THE WORLD’S LARGEST SEED BANK PIONEERS OF THE CANNABIS SEED INDUSTRY
Sensi Seeds pioneered the cannabis seed industry in 1985. Today, the company is the world’s largest cannabis seedbank with over 500 varieties. These genetics and the brand name have become true classics in the cannabis community. The Dutch government chose Sensi Seeds genetics to develop the medicinal cannabis supplied by pharmacies.
Sensi Seeds aims for the normalization of cannabis use and recognition of the plant’s therapeutic and industrial benefits. This led the company to open the world’s first cannabis museum in 1985. The Hash Marihuana & Hemp Museum is now present in both Amsterdam and Barcelona and has welcomed over two million visitors.
Together with the museum, Sensi Seeds regularly hosts the Cannabis Culture Awards. This award celebrates those who have taken a stand for the acceptance of cannabis. Winners include Sir Richard Branson, and former Prime Minister of the Netherlands Dries van Agt.
Sensi Seeds opened its sister-company, HempFlax in 1993. The company developed new processing methods and purpose-built equipment for hemp cultivation. These innovations have since become the industry standard. They are now used by leading agricultural and construction equipment manufacturers, including John Deere.
HempFlax products are widely used in the textile, food, construction and body-care industries. The automotive industry has also adopted hemp, including brands like BMW, Mercedes and Bentley. Hemp is making a successful come-back and HempFlax is leading the way.
The world’s attitude towards cannabis is changing. Countries are now legalising cannabis for medicinal and recreational use. The possibilities for industrial, nutritional and pharmaceutical applications of hemp continue to surprise us. Sensi Seeds will play its part and remain at the forefront of these developments.
Sensi seeds strives for the acceptance of cannabis worldwide and believes that responsible consumption of cannabis can enrich one’s life.
With more than 30 years’ worth of experience in the field of cannabis, Sensi Seeds is fully aware of the crucial role that cannabis can play for humankind. The company is pleased to see the current increase in attention and recognition for the plant worldwide, not only as a medicine but also as a raw material.
Sensi Seeds is committed to preserving the genetic diversity and accessibility of the cannabis plant for future generations, and disseminating information and knowledge about the beneficial effects the plant can have when used appropriately.
