When Heavyweight seeds were originally set up in Spain in 2008, the initial concept was to develop a range of mouth-watering varieties, using only top quality, highly stable, pure strains.
Once the Heavyweight team was convinced that they had reached their goal, with varieties to satisfy all tastes, they were then ready to release their strains onto the European Market in 2010 after 2 years of dedicated, ongoing, research and development.

Heavyweight is already building a name for consistency and quality, time and time again.

The heavyweight ethos………..excellence!
