Description

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.

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 🤜💥🤛

So far Awsome...!
I am stocked that Guava Sundae is here. Two top shelf strains in one Awsome desert package. Since there is no suggested help on how she grows I am going to be very careful on what she wants. Everything is going down to its lowest levels and will increase as needed. Normally I can adjust fertilizers and timers as per the suggested Info. Normally I will drop ten seeds at a time to make sure I have a very good crop going but since I'm having to feel her out I am taking the beginner's route and work them in a set of two. Once I find her sweet spots I will drop them here for all to get knowledge on how she reacts. Hope all is well.

What A Rocket ...
Guava Sundae is now operating in a league of its own. What started as a promising plant a few weeks ago has evolved into one of the absolute standouts of this entire grow. The long, massive colas keep stacking flower after flower and are already coated in an incredible layer of sparkling trichomes. What impresses me the most is the insane frost production. Even the larger sugar leaves are slowly disappearing beneath a thick blanket of resin, making the entire plant look as if it has been dusted with powdered sugar. At the same time, the outstanding structure allows nearly every branch to produce high-quality flowers from top to bottom. 🍨❄️ Guava Sundae currently delivers everything you could ask for from a top-tier autoflower: size, density, resin production, and stunning visual appeal that immediately catches everyone's attention. 🏆 An absolute standout in this run and a serious contender for the crown of the tent. If she continues performing like this over the final weeks, she could easily become one of the most impressive Fast Buds plants I have ever grown. 👑🔥💎🍨❄️

Guava Sundae Auto
Im going into week 6 and she is slowly making her flower transition. She seems to be responding well to low maintenance training so far. She looks like she will be able to handle a good feeding cycle as she does well with only distilled water up to this point minus the soil fertilizers. Happy Frog does wonders for this strain.
