Ruderalis Skunk®
Ruderalis Skunk is the most powerful descendent of Cannabis Ruderalis. By bringing the auto-flowering advantage to Skunk #1’s dependable potency and yield, we have created a tough, rewarding outdoor hybrid for growers with short and unpredictable summers. C.Ruderalis grows wild across north-eastern Europe and is able to survive the harsh and varied climate through adaptations such as its auto-flowering capability. Wild Ruderalis plants flower according to age rather than a declining photoperiod, which allows them to take advantage of the warmest, brightest part of their brief growing season.
Ruderalis Indica was bred to be a psychoactive hybrid with features inherited mainly from C.Ruderalis – broad, tough, bushy plants with the full auto-flowering ability – and a much higher THC content than the wild strain. The Ruderalis Skunk breeding program achieved almost the reverse – a Skunk hybrid that retains the potency, yield and vigour of its exceptional family line, inheriting only the unique flowering trait of the land-race.
Around 50% of Ruderalis Skunk plants will auto-flower. As with Ruderalis Indica, blooming starts at the 5th to 7th set of branches &ndash typically within 5-10 weeks of germination, depending on how quickly plants are able to vegetate in a given climate. The other 50% of plants grown from seed will react to photoperiod, and will be triggered to flower around the same time as strains such as Early Girl and Early Skunk. This makes it possible for garden growers to have a double harvest each season with Ruderalis Skunk, and also means that photo-reactive plants will generally finish larger and yield more.
Ruderalis Skunk conforms to a Skunk growth pattern, gaining slightly more height in blooming than an Indica, without the enormous potential stretch of a Sativa. Auto-flowering individuals will rarely exceed 2m at full size. Flower formation is strong and fast, with thick tops clustering at every internode and extending along stem and branches. Resin production is clearly taken from the Skunk side of the family, covering buds and the single-bladed leaflets which grow from them.

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.
Skunk #1, also referred to as the Original Skunk #1, is a cultivar created by David Watson -- also known as Sam the Skunkman -- that serves as the genetic backbone for many of today’s cannabis strains.
Sources trace its origins to 1970’s California. It’s present in countless crossbreeds, and is a descendant of an Afghani landrace strain crossed with Acapulco Gold and Colombian Gold.
Refining his crops over many years, Sam the Skunkman selected phenotypes with the best yields, early flowering times and dense, resinous buds. It was one of the first well-known indoor cannabis varieties, and won several awards, including 1st place at the inaugural High Times Cannabis Cup in 1988.
