Description
Born from the cross of Guava Auto RF3 and Sundae Thumper F4, Guava Sundae Auto Feminized is part of Fast Buds' Champions Line, a collection built around terpene expression and genetic reliability. The flavor profile leans into citrus and ripe tropical fruit with a sweet, dessert-like finish, and the effects land in a comfortable middle ground, opening with a creative lift before settling into a relaxed, easygoing state. THC sits at 25% and above, so newer growers should approach the finished product with some respect.
In the garden, this feminised autoflower is straightforward to work with. Plants develop a bushy, well-branched structure that handles indoor canopy management without much fuss, and the 8 to 10 week harvest window from seed makes it one of the faster turnarounds you can plan a tent cycle around. Indoor yields run 450 to 600 g/m², a high-end return for an auto, while outdoor plants can produce 200 to 450 grams each under generous sun. For growers chasing serious flavor in a reliable, fast-cycling package, Guava Sundae Auto is worth giving a run.

about this product
Guava Sundae Auto brings citrus-tropical depth and 25%+ THC to a compact, easy-growing autoflower ready for growers who want big results without the complexity.
Guava Sundae Auto is genuinely well-suited to first-time growers — it's part of Fast Buds' Champions Line and was specifically bred for reliability and straightforward cultivation. The feminised autoflowering format means no need to manage light schedules or worry about male plants. Just give it consistent care and it handles the rest.
The profile leans into ripe tropical guava and citrus with a sweet, dessert-like finish that makes it a standout in terms of terpene expression. Fast Buds specifically built this cultivar around flavour intensity, so the aroma in the final weeks of flower tends to be pronounced. Curing properly will reward you with that full citrus-fruit depth.
The effect opens with a creative, mentally engaged lift before gradually settling into a relaxed, easygoing state — so it spans both ends of the spectrum across the session. With THC at 25% and above, even experienced consumers will feel it, and newer users should start slow with the finished product. It's not a couch-lock cultivar, but it's not a light smoke either.
For a first grow or a test run in a new space, 3 seeds is a practical entry point that lets you assess how Guava Sundae Auto performs in your specific environment without a large upfront commitment. Indoor yields are rated high at 450–600g/m², so even a single well-managed plant can return a satisfying harvest in the 8–10 week autoflower window. If results impress, scaling up with a larger pack from there makes sense.
