Green House Seed Company

If you are looking to buy cannabis seeds online, then you have probably heard about the Green House Seed Company before. The Green House Seed Company, sometimes referred to as Green House Seeds Co, is one of the most successful cannabis businesses in the entire world. Below you will find Sirius’ collection of greenhouse seeds, which are some of the most high-quality cannabis seeds you will find in our online Seedshop!

Arjan Roskam – The Man Behind the Green House Seed Company

Arjan Roskam, known by some as the “King of Cannabis”, is the main force behind the Green House Seed Company. For over 25 years he has shaped the evolution of cannabis genetics and has even created some weed strains himself. He also started the Strainhunters mission, which aims at documenting, preserving, and exploring rare cannabis genetics from all around the world. Today Arjan’s creations can be bought online in Sirius’ online Seedshop. Keep reading if you want to know more about the exclusivity and variety of Green House Seed Company cannabis seeds. 

Huge Selection of Green House Seed Company Seeds at

Winner of many international awards (40 High Times Cannabis Cups, 17 Highlife Cups, and many more private awards in many countries), the Green House Seed Company is the leader when it comes to genetic preservation and cultivation of exotic weed strains. If you want to experience the passion and expertise the Green House Seed Company has for cannabis seeds, then you just need to look at the weed strains they offer. If you are looking for haze, how about some Arjan’s Strawberry Haze or Arjan’s Ultra Haze #2, two powerful sativas that were named after the founder of the Green House Seed Company himself. 

If you prefer Kush, you will like strains such as Sweet Valley Kush or Bubba Kush, that give you the ability to completely relax at the end of the day. One of the most popular greenhouse seeds is Exodus Cheese. This delicious indica-dominant strain combines full aromas with a long-lasting stoned effect. Its popularity stems from the fact that it produces record yields in an incredibly short amount of time, making it the perfect strains for growers who want to fill up their stack quickly. These are just some examples of greenhouse seeds, and you can find much more in our online Seedshop!

Autoflowering and CBD weed from Green House Seed Company

Most of the popular Green House Seeds Co strains are also available as an autoflowering variant, for example Exodus Cheese Auto. The professionalism of the genetics & breeding team of the Green House Seed Company shows when one examines their autoflowering CBD lines. Green House Seeds Co has managed to combine some very classic strains not only with the Ruderalis plant (which is responsible for the autoflowering part), but even with CBD genetics. Examples of this are White Widow Auto CBD and Super Lemon Haze CBD. These strains allow you to experience your favorite weed in a less strong and more medicinal version, while being extremely easy to grow thanks to the autoflowering part.
