About

Guava Sundae Auto is a next-generation autoflower built from two proven, award-winning genetics.

This cross combines Guava Auto RF3, a World Cup winner, with Sundae Thumper (Mephisto Genetics), an American Cup champion. The objective was to bring together structure, yield potential, and terpene performance into a single, high-performing line.

From the start, this hybrid shows aggressive growth and strong hybrid vigor, developing into a large, tall plant with a solid frame and consistent structure across the population. She is a high-output plant, capable of delivering serious yields when pushed correctly, with dense stacking and efficient light distribution thanks to well-balanced internodal spacing.

Flowers come in large, heavy, and tightly formed, with strong bag appeal and a clean, uniform finish. The terpene profile hits hard: fresh tropical guava upfront, backed by creamy gelato depth, creating a rich, loud, and fully developed expression. Guava Sundae Auto is bred for growers who want performance, intensity, and results: all in one run.
