AeroGrow does not use genetically-modified seeds, and is committed to never doing so.  We participate in the "Safe Seed Initiative" which is sponsored by the Council for Responsible Genetics, and have signed their "Safe Seed Pledge", which means we will never knowingly buy or sell genetically engineered seeds or plants.  Many of our seed suppliers have also signed this pledge. Our seeds are sourced from large and small vendors from around the world.  Many are heirloom seeds, organic sources are chosen when available, and GMO seeds are never used.
