Description
Born from the cross of Guava Auto RF3 and Mango Runtz F5 Auto, a distinguished line from Mephisto Genetics, Guava Runtz Auto is part of Fast Buds' Champions Line, a curated tier reserved for their most refined genetics. The flavor profile leans unapologetically tropical, layering fresh guava and ripe mango candy over a creamy Runtz finish. Effects carry the balanced character you'd expect from a well-bred indica-sativa hybrid, offering a grounded yet present experience that suits a range of occasions.
As a feminised autoflower, Guava Runtz Auto removes the variables of photoperiod timing and male plant management, making it a practical choice for both new and experienced growers. Fast Buds notes early hybrid vigor in this line, meaning plants establish quickly and make the most of their compact structure from the start. That same compact form keeps canopy management straightforward whether you're running a small tent or a dedicated grow room. With a harvest window of 8 to 10 weeks from germination, this strain fits neatly into back-to-back grow cycles. If you're looking to add a high-resin tropical cultivar to your rotation without complexity, Guava Runtz Auto is a compelling place to start.
