About Lee Roy Auto
The most common mistake growers make with Lee Roy is underestimating how dense the flower structure gets in weeks 6-8, leading to humidity problems inside the buds when airflow is inadequate. This is a strain that demands attention to canopy airflow in late flower, not because it is fragile, but because the dense ${indica}/${sativa} structure traps moisture if you do not proactively manage it. At 22% THC with myrcene-dominant terpenes, the quality ceiling is high, but you have to manage the specific characteristics of this cultivar to reach it.
Growing This Strain: Where Things Go Right and Wrong
The three most common issues growers report with Lee Roy:
1. Nutrient timing at the flip. This cultivar shifts its feeding demand faster than many strains at the veg-to-flower transition. Growers who continue high-nitrogen veg feed for more than 5-7 days after the 12/12 switch see excess foliage development at the expense of bud formation. Switch to bloom nutrients within the first week of seeing pistils.
**2. Late-flower humidity. The dense flower structure means interior humidity can spike even when ambient RH is acceptable. Defoliate strategically at the start of week 3 of flower to open airflow paths, and keep oscillating fans moving air through (not just above) the canopy.
3. Harvest timing. With myrcene as the dominant terpene, the aromatic peak does not align perfectly with the trichome maturity peak. Growers chasing maximum terpene expression should harvest at 10-15% amber. Growers prioritizing potency should wait for 15-20% amber. These are different windows, know which one you are targeting.
Flowering: 8-10 weeks. Yield: 400-500g/m² indoor / 350-500g/plant outdoor. Height: Compact (2-3 ft). Difficulty: intermediate.
Effects and Use
At 22% THC, Lee Roy delivers euphoric, creative, calm effects with a myrcene-influenced character. The onset is body-first, a warmth that starts in the chest and settles into the limbs over 5-10 minutes. At moderate doses, you remain conversational and present. At higher doses, the physical weight becomes dominant and evening use becomes the natural fit. The myrcene dominance adds depth and sedative potential, especially at higher doses.
Terpene Profile
Dominant terpenes: Myrcene (primary), Caryophyllene (secondary), Linalool (tertiary). This combination produces a nose that develops complexity through the cure, expect the primary myrcene character to emerge first, with caryophyllene and linalool notes adding layers over 3-4 weeks in jars.
Who Should Grow Lee Roy
Best suited for growers who value speed and simplicity, autoflowering genetics mean no light schedule changes, compact plants, and harvest in 10-12 weeks from seed. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results.

Lee Roy is our F5 autoflower line. Five generations of selection have fixed both the autoflower trigger and the purple expression the cultivar is known for. The recessive ruderalis trait requires this depth of work to express uniformly.
Stabilize the recessive ruderalis trait in Lee Roy for uniform auto-trigger.
Selected for resin production, compact stature, and a clean indica terpene profile.
