G13 Labs


G13 Labs began with veteran breeders in late–1980s Northern England and later relocated to Spain, where they matured into a respected global seed brand. Their heritage includes the award-winning Granddaddy Purple strain—bred by Ken Estes in California in 2003, a legendary indica known for its grape berries aroma and relaxing effects.

Today, G13 Labs offers a refined lineup of feminized cannabis strains known for fast flowering, robust yields, resin-rich buds, and distinctive terpene profiles. They balance classic genetics with modern breeding techniques to deliver consistency and performance for both home growers and connoisseurs.

Committed to sustainable and organic practices, G13 Labs supports South African growers with elite genetics that are easy to cultivate, medically relevant, and packed with potency. Overgrow is proud to stock these reliable, flavor-forward seeds from this legendary seed bank.
