Permanent Marker from Bighead Seeds is an elite feminised hybrid created from Biscotti x Sherb BX x Jealousy. This is a modern, high-impact strain with serious flavour, strong visual appeal and a huge listed THC level of 33%.
Part of the Bighead Seeds Trailblazer range, Permanent Marker is built for collectors who like loud terpene profiles, high-potency genetics and standout modern hybrids. It brings together dessert sweetness, gassy depth and that unmistakable chemical-funk edge that gives the strain its name. Bighead describes it as “a modern masterpiece of flavour and power,” with euphoric headspace and full-body sedation.
Permanent Marker Strain Profile
This hybrid strain has a bold, premium look. The buds are described as thick and dark green, with deep purple clusters, bright orange pistils and a shimmering layer of crystals. This gives the strain strong bag appeal and a heavy, resinous appearance.
The aroma is loud and unmistakable. Expect a complex mix of skunky, floral and chemical notes, followed by hints of soapy candy and diesel funk. It is not a subtle strain — this is the one that walks into the room before you do.
Genetics: Biscotti x Sherb BX x Jealousy
The lineage is one of the biggest reasons this strain has strong collector appeal.
Biscotti brings dessert-style richness, cookie sweetness and relaxing hybrid depth.
Sherb BX adds creamy, fruity-gassy character and modern Cali influence.
Jealousy brings potency, colour, flavour complexity and premium hybrid appeal.
Together, these genetics create a feminised strain with a bold terpene profile, high THC potential and a deeply relaxing effect profile.

Flavour, Aroma and Effects
Permanent Marker is known for its complex, bold and unforgettable flavour. The profile combines skunky gas, chemical funk, floral sweetness, soapy candy and diesel.
