Silver Haze from Sensi Seeds is now available in this feminised version called Silver Haze #9. Silver Haze is famously the first Haze strain that was capable of being cultivated indoors under artificial lighting with a realistic flowering period and improved yields.

Although praised by sativa connoisseurs Haze itself is quite impractical for indoor growers as it takes 125 days or more to flower, grows ridiculously tall like a vine and produces small yields of exquisite, psychedelic cannabis. This feminised version of Silver Haze was not made available to the public until the newly feminised version had been back-crossed to the original Haze over several generations of selection. This Silver Haze #9 is 80% sativa and can be a stretchy plant to grow. For that reason it is often put into flowering when seedlings/cuttings are only 10 - 15 cm. tall yet they will still finish up at around 100 cm. Its lanky profile means that it is very suitable to be used in a SoG or SCRoG system. The choice is yours whether to veg. longer and train or just keep them short.

Indoor flowering can take between 65 - 80 days but the wait is more than worthwhile. Outdoor harvests will not be ready until late October at the earliest and for this reason cultivation outdoors is conta-indicated for all but warm, dry climates - the Mediterranean will be ideal as long as it is not at too high an altitude. Long colas fill out with contiguous buds which have an open but not airy structure and incredible resin production - density is added thanks to the indica genetics. The effect is very psycho-active, psychedelic, cerebral and uplifting providing mental energy. This will evolve very slowly into a more relaxed state but this is not really recommended as a beginner's strain for smoking/vaping.

About Sensi Seeds

View all Sensi Seeds products

There is no other seed bank in the world that has been coveted with more awards than Sensi Seeds. From the Highlife Cup to the Cannabis Cup, Sensi have achieved unrivalled legendary status in the seed bank world.

In the early 1970’s, the founder of Sensi, Ben, opened a clothes shop in the Dutch city of Rotterdam where he sold homemade clothing. A few years earlier, at the age of seventeen, he smoked his first joint. But it wasn’t until he began making regular trips to Turkey, Afghanistan and Pakistan to purchase textiles that he became aware of the plant’s versatility. He learned about hemp fibre’s suitability as, among other things, a textile and was given cannabis and cannabis seeds by local farmers. Ben discovered that the cannabis plant had so much to offer in spite of it being prohibited and vilified in all corners of the world.

It became one of his passions to collect cannabis seeds from Central and South East Asia and the Asian subcontinent. Back home in the Netherlands, he started to cultivate these seeds in order to learn more about the growth process of this very special plant.

At the start of the 1980’s, the first examples of innovative, stabilised hybrids, such as Haze and Skunk, arrived in Europe from the United States. Ben was one of a mere three Dutch cultivators who were granted access to these hybrids, which are considered an important blueprint for the development of European hybrids.

At the end of the seventies, Ben found out that cannabis seeds did not fall under the cannabis prohibition; it was only the plant that was prohibited and not the seeds. As it was not illegal to sell seeds, Ben reasoned that the production process should not be illegal either. He started his seed company after a lawyer confirmed this insight and in 1985 the Sensi Seed Club, also known as the Sensi Connoisseurs’ Club, came into being. Ben took over a company called the Seed Bank in 1991 and the gene libraries were merged to create the Sensi Seed Bank as we know it today.

Sensi Seeds search for cannabis genetics has never ceased in the last 30 years. Their dedication towards genetic preservation has also never diminished. To this day, Sensi are true to their roots and are now, more than ever, aware that the future of cannabis genetic research lies in its past, in the genetics that started it all.

Sensi genetics offer not only the high yield and range of effects people search for, they actually represent a part of Cannabis’ history.

With a host of award winning strains, it would be unwise to overlook Sensi Seeds, available to buy at Seedsman now.
