Offering top-quality, high-yielding cannabis seeds, Heavyweight Seeds is an increasingly popular choice at the MGS seedbank.

Founded back in 2008, Heavyweight Seeds came to fruition when they visited a cannabis cultivator who had obtained remarkable results from his latest harvest. Having agreed to purchase clones of his mother plants, the Heavyweight team returned to Spain and began their adventure into the world of cannabis seeds. 

The resulting strains created from the cross between the aforementioned mother plants were truly exceptional. In order to preserve those remarkable phenotypes more efficiently, the team decided to create their own gene pool.  Developing a wide variety of regular, auto and feminised seeds, the Heavyweight team have selected only the finest genetics, specifically chosen for their individual characteristics and superior quality.

Following a year of experimentation and development, they were ready to release their cannabis seeds to market and thus, the creation of the Heavyweight Seeds brand was established. 

Focussing on creating hybrid strains that deliver exceptional resin levels, Heavyweight´s genetics typically produce an excellent resin harvest of between 10% and 20% when grown under normal conditions with generic nutrients.

With a simple philosophy of only breeding strains with high production (flowers and resin) and potent effects, Heavyweight Seeds are now well established as serious players in the hugely competitive cannabis seed market. Indeed, cultivators who choose from the extensive Heavyweight Seeds catalogue can be confident that they are selecting cannabis seeds of the highest quality, sure to deliver bountiful harvests.

Boasting an extensive library of seeds that continues to expand, Heavyweight Seeds offers consumers a wide variety of regular, feminised and autoflowering strains, including 2Fast 2Vast, currently one of the most popular auto-flowering strains available today. Other notable choices in the Heavyweight collection include Dream Machine, Fruit Punch and Strawberry Cake.

With almost fifteen years of knowledge and experience behind them, Heavyweight Seeds now come with a heavyweight reputation, with their impressive selection of cannabis seeds earning several cannabis cup awards and nominations in recent years.

Whether you´re looking for a potent indica-dominant cannabis strain or an uplifting sativa hybrid, Heavyweight Seeds’ high-quality genetics ensure only the most rewarding growing experience.
