The original auto chemdawg gave me exceptional yield. She developed a few side branches and each side branches formed 12 inch plus cola. The smell combines both kush and berry hint.
The red poison auto grows vigorously. She spent three weeks in the Vegetative phase and transitioned into flowering. Bud's structure is a bit loose but the smell is amazing.
I would recommend the red poison auto if you plan for a quick grow with exotic looks.
