Permanent Marker

Permanent Marker is a highly potent hybrid cannabis strain famous for its rich, complex genetics, high THC levels (25%–35%), and a distinct aroma that smells exactly like a chemical marker. It was crowned Leafly's Strain of the Year in 2023. Part of Permanent Marker's rapid success can be attributed in part to its strong genetic foundation. It’s a cross of Biscotti, Sherb Bx, and Jealousy—each a respected strain in its own right. Through targeted backcrossing, these genetics have been refined by Seed Junky to produce the strain’s distinctive aroma and potent, well-balanced effects. ?These parent strains share lineage with the iconic Gelato and, further back, Girl Scout Cookies, cultivars that helped define the modern cannabis era in early 2000s California. Permanent Marker's genetics ensure vigorous growth while maintaining manageable plant structure. This photoperiod strain thrives in stable environments, flowering within 8-10 weeks. Plants maintain medium heights while producing generous amounts of dense, resinous buds. The sturdy stems support their weight well throughout flowering. Outdoor cultivation works best in warm climates with low humidity during flowering. Plants benefit from good airflow around developing buds. Permanent Marker blend Biscotti and Jealousy genetics into a gassy, potent hybrid that leaves a lasting impression. This elite cross combines two legendary lineages known for their exceptional resin production and memorable effects. The result is a plant that delivers both commercial yields and connoisseur quality.
