Cultivar Details:

Plant physiology: Lemon Vuitton (LV) stays relatively short and stocky, with good, sturdy branching. The plants bush out well when only the terminal shoot is topped early. Growth is vigorous for a broadleaf type plant with internodal spacing wide enough for good airflow around the flowers late in flowering. Flowers are white/silver with extreme resin content.

Average yield: With a two-week vegetative growth time, expect 2 to 4 dry ounces per plant depending on many factors, including selection preferences. At nine plants per light, LV yields an average of 2.5 lbs./1000-watt light.

Flowering time: Swamp Boys harvest at 59 days in a greenhouse, although expect some selections to go to 63 days or more. Generally, the terpene profile gets deeper and more complex after 60 days if environmental conditions are kept at optimal levels—cooler temperatures with lower light levels or higher Kelvin (a unit of measurement used to express color temperatures).

Ideal light-intensity setting: LV can handle high light levels throughout the growth cycle, up to 750 watts per meter. That said, the flower structure has large bracts that prefer a slightly lower light level and cooler temperatures in the last 10 to 14 days. This protects the flower from drying out and ensures robust terpene production.

Ideal cultivation environment temperature: The LV plants Swamp Boys grew out did best at 78 degrees Fahrenheit daytime average, with cooler nights (72 degrees Fahrenheit) the last two weeks.

Ideal cultivation environment relative humidity: LV likes a relative humidity (RH) of 60% throughout most of its lifecycle, falling between 40% and 50% as Swamp Boys lower the temperatures during the last two weeks of flowering.

Water needs: On average, LV is a slightly light drinker depending on the leaf area index and level of crop steering. Phenotypes that prefer a slightly higher RH usually use slightly less water. LV struggles a little with aggressive dry-downs due to the plant structure and broad leaves, so the plant prefers a more vegetative irrigation model.

Nutrient needs: LV seems to perform best with a lower nutrient strength that corresponds with its irrigation preferences.

Cannabinoid profile: High THC (waiting for official test results).

Terpene profile: LV has a lemon, leather and fuel base with whiskey cream notes, which are some very interesting terpene combinations that immediately stood out. (Waiting for test results.)

Varietal resistance: LV flowers are fairly dense with large bracts, so humidity must be controlled during last stages to reduce the chance of Botrytis. Too much heat and high light levels in the later stages of flower can dry out bracts/flowers and reduce or change the terpene expression of this variety.
