Lemon Tree Auto: sweet lemon, lime and a hint of mint
Lemon Tree Auto grew out of a selection project built around the original Lemon Tree cut. Fast Buds tested several phenotypes in search of a clean, sweet citrus, then crossed it with Z-Up Auto to add sweet, minty and floral notes. The result is an F4 auto, 65% sativa and 35% indica, with up to 27% THC.
Vigorous, stable and productive
Plants are vigorous and stable, with dense buds and heavy trichome production. They reach 70–120 cm (XL size) and yield 450–600 g/m² indoors and 60–300 g per plant outdoors. Fast Buds gives a harvest time of 8–9 weeks.
Aroma, flavour and effect
A sweet lemon base with minty and floral nuances. On the palate: lemon, lime (like lime soda), fresh mint and a sour edge. A fresh, complex aroma that develops as the buds are handled.
At 65% sativa, this is a daytime auto. The feelings growers report most are energy and happiness, followed by a giggly, uplifted yet relaxed state. A lively, fresh effect, just like its flavour.

Growing tips
Like all autoflowers, Lemon Tree Auto switches to flowering on its own, with no change in light schedule. Sow it straight into its final pot to avoid transplant stress, give it 18–20 hours of light indoors and start feeding at gentle doses. For week-by-week doses, see our Grotek feed chart for autoflowers.
