Lemon Tree Auto

Lemon Tree Auto is a terpene-led FastBuds release built around a bright citrus profile rather than just raw speed or size. It is available as feminised autoflowering seeds, with genetics listed as Lemon Tree Cut x Z-Up Auto. FastBuds worked from the original Lemon Tree cut, selecting through multiple in-house phenotypes for a clean, sweet citrus expression, then used Z-Up Auto to add a more modern minty and floral layer.

The balance is 65% sativa and 35% indica, so the shape and feel of the line sit on the sativa-leaning side while keeping a fairly balanced plant structure. THC is listed at up to 27%, with CBD below 1%. That gives Lemon Tree Auto a strong headline potency figure, but the real point of interest is the aroma: sweet lemon at the base, with fresh mint, lime, lime-soda sharpness and sour notes coming through around it. The floral edge stops the citrus from feeling flat.

Plants are described as vigorous and stable across the population, with dark green colour, balanced structure and an XL size rating. Height is given as 70–120 cm, making it a medium-to-tall autoflower depending on the setup and expression. FastBuds gives a flowering time of 8–9 weeks, and the line is suited to indoor, outdoor, greenhouse and mixed-light growing.

The flowers are dense and resin-rich, with consistently high trichome production. A low leaf-to-flower ratio is a useful practical detail here, as it should make the finished buds easier to trim and work with. The breeder also points to extraction potential, which fits the high resin output and terpene-first breeding aim.

Indoor yields are listed at 450–600 g/m², while outdoor plants can produce 60–300 g per plant. Climate guidance runs from very hot through to cold, with the most suitable range sitting around hot, moderate and cooler conditions rather than very cold extremes. If you want a sativa-leaning auto with a sharp lemon profile, minty freshness, solid resin and a defined 8–9 week finish, Lemon Tree Auto has a clear job and sticks to it.
