Our take
CBD Auto 20:1 is a balanced sativa-indica autoflower bred specifically for a high CBD-to-THC ratio — up to 20% CBD with THC staying well below 1%. It suits growers who want a substantial CBD harvest without navigating complex light schedules. The forgiving autoflower life cycle and straightforward growth pattern make it a reasonable choice for beginners and a practical one for experienced growers scaling up.

Growing notes
CBD Auto 20:1 fits indoor, outdoor, greenhouse, and mixed-light setups equally well. The full cycle runs 9–10 weeks from seed with no light-schedule adjustment required. Indoor yields land between 1.1 and 1.5 oz per square foot; outdoor plants produce 2–6 oz each. Plants reach 27–35 inches at harvest — a large size class for an autoflower, so plan vertical space accordingly.
