Runtz × Permanent Marker is a terpene-dense hybrid that combines the sweet, candy-forward profile of Runtz with the sharp, fuel-and-ink character associated with Permanent Marker. Lab testing shows total THC approaching 27% alongside an elevated terpene content of 4.48%, driven by caryophyllene, limonene, myrcene, and farnesene. The aroma blends sugary citrus notes with pungent gas, floral undertones, and a distinct marker-like sharpness. Effects are fast-acting and mentally stimulating, followed by a smooth, grounding body relaxation. Flowers are dense and highly resinous, making this cultivar well suited for both premium flower production and terpene-focused applications.
