Sumo Seeds - Cold Thunder: Bred For The Cold

Are you a Siberian stoner or a Canadian cannabis connoisseur? Or perhaps a Baltic bong-hitter? Not all cannabis growers have the luxury of year-round warmth. However, some regions of the world are remarkably cold, which makes the beginning and end of the outdoor growing season quite brutal for cannabis plants.

But fear not, the innovative minds of cannabis breeders view obstacles and challenges as opportunities instead of deterrents. Cold Thunder is a strain that was developed purely to handle cold outdoor temperatures with ease. This almost pure sativa (85%) was created using the hardy and durable genetics of Early Sativa and Alaskan Thunder.


Cold Thunder produces flowers with a high THC content, inducing a powerful effect. The sativa-dominant genetic makeup results in creative, motivating, and focus-enhancing experiences. This feeling eventually turns into a relaxing body stone, made possible by the slight presence of indica genetics.

These effects make Cold Thunder an excellent daytime smoke during creative projects or demanding work tasks that require prolonged focus.


The trichomes of Cold Thunder work hard in cooler climates and turn out terpenes than contribute to some great flavours and scents. The strain is defined by aromas of earth, sweetness, and citrus fruits, along with a spicy kick.


Not only does Cold Thunder survive in colder temperatures, she absolutely thrives in them. Her tough nature allows her to explode to mammoth heights of 350cm when grown outdoors in garden beds or large pots. Her root system grows extremely large and can easily support such massive specimens.

The enormous size of Cold Thunder results in some staggering yields that clock in at approximately 600–1000g/plant. The flowers themselves are massive and extremely compact. Stakes may be needed in order to support the branches during the late stages of the flowering phase. This outdoor beauty will be ready to harvest sometime in September, well before the winter frost really sets in.
