Appearance

Permanent Marker XL Auto typically exhibits a medium to tall stature for an autoflower, often reaching between 80-120 cm indoors under optimal conditions. Plants tend to develop moderately tight internodal spacing, promoting dense cola formation. The foliage may start as a vibrant green and can darken, with some phenotypes showing purple hues under cooler temperatures. Buds are generally compact and weighty, featuring a dense structure with minimal excess sugar leaf, and are covered in a conspicuous resin layer.

Aroma & Flavor

The strain's aroma is characterized by a distinct "permanent marker" or dry-erase pen scent, complemented by underlying notes of candy sweetness and a gassy, solvent-like edge. Upon grinding, this complexity intensifies, releasing pungent citrus notes, often described as limonene-forward, alongside hints of lavender and pepper. The flavor profile mirrors the aroma, presenting a blend of sweet candy, floral, and citrus elements with a unique chemical sharpness.

Effects

Permanent Marker XL Auto is reported to produce balanced effects, often described as cerebral and conducive to creativity. The indica influence contributes to dense bud structure and resin production, while the sativa component is associated with mental clarity and a more buoyant experience at moderate consumption levels.

Terpenes & Cannabinoids

This hybrid is noted for its significant terpene content, with Limonene, Caryophyllene, and Linalool frequently cited as prominent. Other terpenes such as Pinene, Humulene, Ocimene, and Nerolidol may also be present, contributing to its complex aromatic profile. THC levels are reported to range between 15-25%, with CBD content below 1%.

The strain is considered forgiving and suitable for various growing environments, adapting well to different substrates and conditions.

Origins & Lineage

Permanent Marker XL Auto is a cross between the popular U.S.-bred Permanent Marker photoperiod strain and a European autoflowering ruderalis line. The original Permanent Marker is known for its dessert-like profile, often linked to genetics such as Biscotti, Jealousy, and Sherb.
