Scientific & Botanical Overview

Limelight exhibits classic sativa-leaning morphology, producing elongated colas with dense resin coverage and a bright lime-green coloration. The plant combines the vigorous growth of Sour Diesel with the tighter structure and resin density of MK Ultra.

Botanically, the cultivar is associated with elevated concentrations of terpinolene and limonene, supported by caryophyllene and myrcene. This terpene profile is responsible for its sharp citrus aroma and energetic sensory experience.
