Our take

Lemon Tree Auto brings together Lemon Tree and Z-Up Auto genetics in a sativa-leaning (65/35) feminized autoflower that finishes in just 8–9 weeks without any light-schedule changes. Potency reaches up to 27% THC, and the flavor profile runs from fresh mint and lemon to a sharp lime-soda sourness. A good fit for growers with some runs under their belt who want a high-yielding, flavorful plant on a fast timeline.

Completes seed-to-harvest in 8–9 weeks indoors or out — no light-schedule flip needed
Indoor yields of 1.5–2 oz/ft² and up to 11 oz per plant outdoors from an XL-sized plant (28–47 inches tall)
Distinct citrus-and-mint aroma from Lemon Tree lineage, with up to 27% THC at finish

Growing notes

Lemon Tree Auto suits indoor tents, outdoor beds, greenhouses, and mixed-light setups equally well. Expect plants to reach 28–47 inches — plan vertical space if growing indoors. The 8–9 week total cycle is measured from germination, so no timing guesswork. Intermediate growers will get the most from her; solid environmental control and adequate feeding will push yields toward the top of the range.
