What Are Autoflowering Cannabis Seeds?

Autoflowering cannabis seeds are seeds that have been produced by using the genetics of the cannabis Ruderalis plant.

The Ruderlais genetics produce plants that are short-growing, resilient, and automatically start to flower after a certain period of time. Their short vegetation period also means that buds are produced quicker.

These attributes make Autoflower seeds perfect for beginners and people who want an easier grow.
