Lemon Tree Auto™ was developed around the original Lemon Tree cut, with Fast Buds selecting for a specific expression that preserves intense, clean and sweet citrus characteristics while maintaining depth and balance. The line was then combined with Z-Up Auto to introduce additional sweet, minty and floral dimensions to the terpene profile, resulting in a distinctly Sativa-leaning autoflower.
The aroma is the defining feature of this variety. Its profile begins with a sweet lemon foundation and develops into refreshing mint, lime-soda and subtle floral notes, creating a fresh and layered citrus character rather than a simple lemon profile. Fast Buds specifically positions Lemon Tree Auto as a terpene-focused variety for those who place aromatic quality high on their list of priorities.
Visually, the variety is characterized by dark-green plants and dense, resin-rich flowers with substantial trichome production. The low leaf-to-flower ratio is also highlighted by Fast Buds as one of the line's distinguishing structural characteristics.
Overall, Lemon Tree Auto™ combines a strong citrus identity with minty freshness, floral depth and a pronounced resinous character, while retaining the compact XL classification and relatively short 8–9 week flowering period specified by Fast Buds.
