Xtreme Seeds stands out in the cannabis world as a Spanish seed bank with a remarkable reputation. Established by a team of Spain's most skilled growers and breeders, this brand has carved a niche in the market with its unique approach to cannabis cultivation.
Unveiling the Potential of XXL Autoflowers
At the heart of Xtreme Seeds' innovation are their XXL autoflowering strains. These varieties are not just any regular seeds; they are the result of extensive plant selection to identify the best parents for hybrid creation. This meticulous process has led to the development of genetics with a distinct personality, setting Xtreme Seeds apart in the industry. Their range includes some of the most sought-after autoflowering and feminized seeds, designed to maximize the potential of your grow space.
One of the crowning achievements of Xtreme Seeds is their Giant Autoflowers collection. Launched in 2009, after two decades of dedication to medical cannabis cultivation and breeding, this collection features plants that grow into towering figures. These 'monsters' are known for their super high yields, exceptional THC levels, and perfect flavor profiles. A standout in this collection is the High Mass ASB, a strain that boasts metallic tastes and impressive yields of up to 200g/plant outdoors or 500g/m2 indoors, all within 90-100 days from seed to harvest.
Collaborations and Genetic Breakthroughs of Xtreme Seeds
The period between 2015 and 2018 marked a significant phase for Xtreme Seeds, as they embarked on collaborations with other seed banks, notably Blue Stone Sanctuary. These partnerships were focused on enhancing the genetics of existing strains and introducing new, improved versions. The result was an expanded catalog of top-notch ASB autoflowers, including strains like Blue Kush 99 Auto, which promises yields of 400-500g/m2 in just 65 days from seed to harvest.
Deep Chunk, a 100% Indica strain ideal for extractions and breeding, emerged from these collaborations, showcasing Xtreme Seeds' commitment to innovation and quality. This period of collaborative growth not only enriched their strain offerings but also cemented their position as a leader in the cannabis seed industry.
Today, Xtreme Seeds continues to work closely with breeders, constantly exploring new genetics and better cannabis cultivars. Their goal is clear: to elevate the cannabis industry to new heights with every strain they develop. With a technical team dedicated to exhaustive analysis and quality control, Xtreme Seeds ensures that each product meets the highest standards, a fact corroborated by thousands of satisfied customers worldwide.
