Description

Guava Sundae Auto is part of our new Champions Line, a breeding project built around combining the most awarded autoflower genetics into new performance driven hybrids. This early F1 release brings together two elite winners: our Guava Auto RF3, champion of the latest Autoflower World Cup, and Sundae Thumper F4 by Mephisto Genetics (Gelato #45 x Forum Stomper), awarded Best Autoflower Hybrid at the American Autoflower Cup 2025.

The objective behind this cross was to unite Guava’s explosive tropical intensity and proven performance with Sundae Thumper’s resin production, and creamy terpene profile, creating a balanced, flavor forward hybrid built from true champions.

From the early stages, Guava Sundae shows strong F1 hybrid vigor, developing medium-sized, bushy plants with sturdy lateral branching.  She responds well to light training or leaf tucking, encouraging multiple dense colas and strong yield potential relative to her size.

Sounds interesting 🧐
When are going to upgrade your Papaya Cookies 🍪 Auto? Personally, I think if you cross Papaya Cookies x Gorilla 🦍 Cookies 🍪 you may have something special but your breeder is the expert and he'll decide what's the next best thing for Papaya Cookies upgrade/level-up. Thanks for being awesome 🤜💥🤛

Customer questions & answers

How does the Champions Line differ from your regular strains?
The Champions Line features crosses between our genetics and other breeders’ award-winning strains, whereas our “regular” autoflowers are established genetic lines developed from our own proprietary genetics.
Why are these F1 seeds? Are they less uniform?
These seeds are produced from our experimental projects and are especially created for those who want to be among the first to try exciting new crosses and the next big thing. We don’t plan to continue production unless they pass all our internal testing standards. And yes, F1 seeds do tend to be less uniform; however, they are extremely vigorous and deliver higher overall performance. As we continue to work on these lines, they will become more and more stable, just like our “regular” autoflower seed lines.
What environments is Guava Sundae Auto best suited for?
F1 plants are very hardy and resilient. As long as you provide good environmental conditions, whether indoors, outdoors, or in greenhouses, they will produce excellent results.
Which parent strains were used to create Guava Sundae Auto?
Guava Sundae Auto is a cross between Sundae Thumper F4 (Gelato #45 x Forum Stomper) and our Guava RF3, which comes from ((Gorilla Cookies Auto F5 x Kosher Cake) x Tropicana Cookies Auto F5).
How was the selection process for this strain?
Our Champions Line seeks to produce seed crosses exclusively with award-winning strains. In this case, we wanted to experiment with Sundae Thumper F4 from Mephisto and our Guava RF3 to create a creamy twist on the fruity Guava terps. Sundae Thumper F4 won Best Hybrid at the American Autoflower Cup 2025 and brings many strong qualities that can only enhance our Guava RF3.
