What is the Permanent Marker strain?
Permanent Marker is an indica-dominant hybrid from Seed Junky Genetics in Los Angeles, built from Biscotti, Sherb Bx1 and Jealousy, and it was Leafly's 2023 Strain of the Year. Its name matches its smell: a sharp, solvent-like note layered over sweet candy, florals and fuel. Seed versions sold by Royal Queen Seeds and Zamnesia list about 70% indica and 55–65 days of flowering, and Leafly reports retail flower averaging roughly 25–30% THC.
Ratio from Royal Queen Seeds and Zamnesia, which sell seed versions. Leafly files it simply as a hybrid.
Leafly describes sweet, marker-like fumes of grape candy and creamy berry with a solvent edge, the smell most reviews mention first.
Permanent Marker strain specs
Permanent Marker's pedigree and potency come from SeedFinder and Leafly; the grow figures come from Royal Queen Seeds and Zamnesia, two seed makers that sell feminized versions under ideal-conditions claims. The original reached dispensaries as Seed Junky's own selected plant, so seed-grown plants can differ a little from that flower.

Where does the Permanent Marker strain come from?
Permanent Marker was bred by Seed Junky Genetics in Los Angeles, which crossed a Biscotti × Sherb Bx1 plant with its own Jealousy. Biscotti is a Cookies-family cut usually listed as Gelato 25 × South Florida OG, and Sherb Bx1 is a backcrossed Sherbet line. Jealousy, Leafly's 2022 Strain of the Year, is Sherbert Bx1 × Gelato 41, so Sherbet genetics appear on both sides of Permanent Marker's family tree.
Seed Junky launched Permanent Marker in 2022 on both US coasts, and Leafly tracked its menu availability climbing from about ten stores in August 2022 to 587 stores by November 2023, which Leafly said led the country in year-over-year menu growth. Feminized seed versions now come from European seed makers such as Royal Queen Seeds and Zamnesia, which list the same (Biscotti × Sherb Bx1) × Jealousy pedigree.
Does Permanent Marker really smell like a marker?
Yes, Permanent Marker's name matches its smell, which many reviewers compare to a freshly uncapped marker pen. Leafly describes sweet, marker-like fumes of grape candy and creamy berry with a solvent note, and Canadian retail listings mention soapy funk with candy and floral gas. Leafly's own flavor tags for it are chemical, ammonia and tobacco rather than fruit.
Watch for look-alike names. SeedFinder lists other crosses sold as Permanent Marker by unrelated breeders, so check that a listing gives the (Biscotti × Sherb Bx1) × Jealousy pedigree.

How do you grow Permanent Marker seeds?
Permanent Marker seeds grow into bushy, medium-height plants that are easy to moderate to handle: veg for 4 to 6 weeks, top and spread the branches, flower for 8 to 9 weeks under 12/12, and run strong carbon filtration because the smell gets loud late in bloom.
- Germinate3–7 days
Permanent Marker seedlings come up stocky with compact node spacing, a trait of its Cookies and Sherbet ancestry.
- Vegetate4–6 weeks indoors
Top once and use LST to open the dense, Christmas-tree frame so the lower bud sites get light.
- Flower8–9 weeks
After the 12/12 switch, Permanent Marker stretches moderately and packs on dense, resin-heavy buds; some plants show purple tones.
- HarvestDay 55–65 indoors · late Sept–Oct outdoors
Harvest when most trichomes look cloudy, then dry slowly to hold on to the candy and solvent notes.
Grow tips for Permanent Marker
- Plan for the smell. Permanent Marker's solvent-and-candy funk is strong in late flower, so size the carbon filter for the whole tent before bloom starts.
- Thin the canopy. Tight node spacing traps humid air. Remove crowded inner leaves around the switch and again about three weeks into bloom to lower bud rot risk.
- Keep height in check. Indoor plants usually finish at 80–120 cm, which suits most tents, and a single topping plus a SCROG net keeps the canopy level.
- Expect some seed-to-seed variation. Feminized Permanent Marker seeds come from seed makers working with the original lines, so color and smell can vary. Keep a clone of your favorite plant.
- Outdoors, finish before the rain. Permanent Marker comes in from late September to October in the Northern Hemisphere, and its dense colas need dry autumn weather.

Great pick if you
- Want a modern, high-THC dessert hybrid with a famous name

- Are sensitive to very potent THC levels
- Grow outdoors where autumn rain arrives in September
