People often talk about their “super autos”—plants that stay easy but stretch tall. Whether in a greenhouse, outdoors, or indoors, the genetics hold steady. These seeds come from a deep understanding of Cannabis Ruderalis, and they tend to resist common pests. Even newer growers say they get good harvests without too much trial and error.
