Permanent Marker Strain Review: Seed Junky’s Powerhouse Indica

The Permanent Marker strain is Seed Junky Genetics’ Biscotti x Sherb BX x Jealousy cross, famous for an aroma that really does smell like a fresh marker.

I’m James Bean, founder of Seeds Here Now since 2010. This review covers Permanent Marker’s lineage, its award, the aroma and the Marker crosses it inspired.

Seeds Here Now sells authentic breeder packs to adults 21+. We do not provide growing instructions, and nothing here is a medical claim.

Permanent Marker at a Glance

Permanent Marker Genetics and History

Permanent Marker is a three-way cross of Biscotti, Sherb BX and Jealousy, bred by Seed Junky Genetics and brought to fame by Doja Pak. Leafly named it 2023 Strain of the Year.

It quickly became a breeding parent too. LIT Farms used it in Lit Marker and Rainbow Marker, and many Marker crosses followed. Read our LIT Farms review.

Permanent Marker Aroma and Appearance

The Permanent Marker strain smells like its name: sharp and solvent-like, with gas, floral soap, candy and a funky edge. It is one of the most distinctive aromas of the decade.

Buds are dense and heavily frosted, often with deep purple tones.

Buying Permanent Marker

Permanent Marker seeds are among the most counterfeited names right now. Look for the original breeder or an accountable seller. We carry Automatically Delicious Permanent Marker autoflower and Marker crosses from breeders such as Raw Genetics.

Leafly Strain of the Year 2023

The Permanent Marker strain reached a much wider audience when Leafly named it its 2023 Strain of the Year. Leafly’s annual pick is based on what its editors and readers saw rising across legal markets that year, and Permanent Marker had gone from a little-known exotic to one of the most talked-about names on dispensary menus in a short time.

For buyers, an award like that is a double-edged thing. It confirms that the Permanent Marker strain is a genuinely important modern line, but it also means the name gets copied. After the award, a lot of packs and products started using the Permanent Marker name, and not all of them trace back to the original breeder. You can read Leafly’s own write-up in the sources below.

The award also says something about where cannabis taste was heading in 2023. Permanent Marker is not a pure dessert strain and not a pure gas strain. It sits in between, and that blend is exactly what made it stand out.

Seed Junky Genetics: The Breeder Behind Permanent Marker

Seed Junky Genetics is the California breeding project credited with creating the Permanent Marker strain. Seed Junky Genetics built its name in the 2010s with some of the most influential exotic lines of the decade, and it is widely credited with popularizing Wedding Cake and with releasing Kush Mints and Jealousy.

What ties the Seed Junky Genetics catalog together is a focus on modern Cookies, Gelato and Sherbet family genetics, refined into lines with loud, layered aromas. Permanent Marker fits that pattern perfectly, since all three of its parents come out of that same family.

If you want to understand the Permanent Marker strain, it helps to know the rest of the Seed Junky Genetics catalog. Our Seed Junky Genetics brand page covers the breeder in more depth, and our Wedding Cake strain review covers the line that made the breeder famous.

Seed Junky Genetics releases tend to be limited and are often drops rather than permanent catalog items.

Doja Pak and the Rise of Permanent Marker

The Permanent Marker strain is also closely associated with Doja Pak, a brand known for exotic flower and distinctive packaging. Doja’s releases helped introduce Permanent Marker to buyers who had never heard of the breeder, and the brand’s name still appears alongside the strain in many write-ups.

This split between breeder and brand is common in modern cannabis. A breeder creates and selects the genetics, while a brand or grower makes the flower famous. When you collect Permanent Marker seeds, the breeder is the name that matters most, because the breeder is the source of the genetics in the pack.

Parent One: Biscotti

Biscotti is usually listed as Gelato #25 crossed with South Florida OG, and it comes out of the Cookies family of genetics. It is known for a sweet, cookie-dough and coffee-like aroma with an OG fuel note underneath.

In the Permanent Marker strain, Biscotti is widely credited with the creamy, bakery side of the aroma and with the dense, frosty look of the flower. It is also the parent that carries some of the OG gas from South Florida OG into the cross.

We carry Dr. Blaze Biscotti feminized seeds for buyers who want to hold one of Permanent Marker’s parents alongside the finished line.

Parent Two: Sherb Bx

Sherb Bx is a backcross of Sunset Sherbet, which itself is usually listed as Girl Scout Cookies crossed with Pink Panties. A backcross breeds a line back toward one parent to fix that parent’s traits, so Sherb Bx is meant to lock in what made Sunset Sherbet special.

Sunset Sherbet is famous for a sweet, fruity, sherbet-like aroma and for purple coloring. In the Permanent Marker strain, the Sherb Bx side is widely credited with the fruit, the berry tones and much of the purple color buyers see in photos.

Our Sunset Sherbet strain review covers the history of this parent in more detail.

Parent Three: Jealousy

Jealousy is another Seed Junky Genetics line, usually listed as Sherbet Bx1 crossed with Gelato 41. It became a sought-after exotic in its own right, known for a sharp, gassy and slightly sweet aroma.

In the Permanent Marker strain, Jealousy is widely credited with the gas and with the funky, inky edge that gives the strain its name. Because it also carries both Sherbet and Gelato, it reinforces the family traits already coming from the other two parents.

Jealousy is easy to find under its own name; browse our Jealousy listings to see the lines that use it.

The Three Parents Side by Side

Seen this way, the Permanent Marker strain looks less like a random combination and more like a deliberate blend: one parent for dessert, one for fruit and color, and one for gas.

Why a Three-Way Cross Is Unusual

Most named strains are simple two-parent crosses. The Permanent Marker strain is listed with three parents: Biscotti, Sherb Bx and Jealousy. In practice, a three-way cross usually means that two of the lines were crossed first and that result was then crossed with the third.

Three-way crosses are harder to work with because each new parent adds more possible combinations of traits. That makes careful selection even more important, and it is one reason a breeder’s reputation matters so much with a line like this. A well-selected three-way cross can combine the best of three lines; a poorly selected one can be all over the place.

If you want to learn the vocabulary of crosses, backcrosses and selections, our cannabis breeding 101 guide is a good place to start.

The Cookies and Gelato Thread

Look closely at the three parents and you will see the same family running through all of them. Biscotti comes from Gelato #25. Sherb Bx comes from Sunset Sherbet, which comes from Girl Scout Cookies. Jealousy comes from Sherbet and Gelato 41, and Gelato itself descends from Sunset Sherbet and Thin Mint Girl Scout Cookies.

So while the Permanent Marker strain is a three-way cross, it is really a concentrated expression of one modern family: Cookies, Sherbet and Gelato. That shared background is part of why the strain is more consistent than a random three-way cross might be.

For more on these relatives, see our Gelato strain review and our Runtz family tree, which traces another branch of the same Gelato and Zkittlez era.

Permanent Marker Appearance Up Close

Photos of the Permanent Marker strain usually show compact, rounded flower with a thick layer of frost. The color ranges from lime green to deep violet, often within the same bud, with bright orange pistils running across the surface.

The purple tones are usually credited to the Sherbet side of the family, while the heavy frost is credited to Biscotti and the Gelato cuts. Under magnification, the trichome heads look dense and cloudy, which is a big part of the strain’s visual appeal for buyers and photographers.

Permanent Marker Terpenes

Terpenes are the aroma compounds that give cannabis its smell. The Permanent Marker strain is usually reported to carry a terpene mix led by beta-caryophyllene and limonene, with myrcene, linalool, alpha-pinene and humulene in smaller amounts.

Terpene levels vary from sample to sample and from lab to lab, so treat any exact percentages as rough guides. We describe terpenes for aroma only and make no claims about effects. Our guide to cannabis-derived terpenes explains how these compounds are measured.

The Permanent Marker Flavor Profile

Buyers and reviewers describe the Permanent Marker strain in layers:

• First impression: sharp gas and diesel with a sweet candy edge.
• Middle: creamy vanilla and mixed berry, the dessert side of the family.
• Finish: a lingering fuel funk with floral spice and a peppery note.
• Overall: sweet and gassy at the same time, which is the balance that made it famous.

That combination of dessert and gas is the signature of the Permanent Marker strain. Pure dessert strains can feel one-note, and pure gas strains can feel harsh on the nose. Permanent Marker sits between them.

Why It Is Called Permanent Marker

The name is usually explained by the aroma. Many people describe a sharp, inky, almost solvent-like note in the Permanent Marker strain that reminds them of opening a fresh marker. Combined with the sweet side of the family, it makes an aroma that is easy to recognize and hard to forget.

Strain names are often playful, and this one does what a good name should: it tells you something real about the smell.

The name also works as a quiet joke about the strain’s reputation. Buyers often say the aroma lingers in a room long after a jar is closed, the way a marker’s smell lingers after the cap goes back on. Whether or not that was the breeder’s intent, it is how many people remember the Permanent Marker strain.

Permanent Marker Expressions: Fuel, Sweet and Balanced

Like any modern three-way cross, the Permanent Marker strain shows more than one expression. Buyers usually describe three:

• Fuel-forward: heavy gas and diesel with only a little sweetness, often lighter green in color.
• Sweet-forward: vanilla and berry up front, often with deep purple tones and bright orange pistils.
• Balanced: an even mix of fuel and sweet, purple-green flower with a heavy coat of frost. This is the expression most people picture when they think of Permanent Marker.

These are community descriptions, not lab categories, and the split between them varies by seed batch. They are a useful way to talk about the line, and they show how much variety a single pack of Permanent Marker seeds can hold. Read about cannabis trichomes to understand the frost buyers talk about.

About Permanent Marker THC Numbers

The Permanent Marker strain is usually reported to test in a high range, often quoted around 25% to 35% THC. Those numbers come from flower samples sold in legal markets, and they vary a lot from sample to sample.

Lab results depend on the specific plant, how it was grown, how the sample was handled and which lab ran it. Two samples of the same strain can test several points apart. That is why we treat THC figures as reported ranges, not guarantees, and why we never promise any result from a pack of seeds.

Seeds themselves contain no meaningful THC. The figures you read describe flower from mature plants, not the seeds in a buyer’s pack.

The Permanent Family: Related Lines

Because the Permanent Marker strain became so popular so quickly, breeders started using it as a parent. A few of the lines buyers see most often:

Not every line with Marker in its name is a direct descendant of the Permanent Marker strain, so check the lineage on each pack.

How Breeders Use Permanent Marker as a Parent

Once a strain wins a major award, breeders start testing it as a parent. With the Permanent Marker strain, breeders are usually trying to add its gas and frost to another line without losing that line’s own character.

Crossing it with White Runtz, for example, aims to combine Permanent Marker’s fuel with a candy-forward Runtz parent. Autoflower versions aim to carry its aroma into a different seed type. Each new cross is its own line, so judge it by its own breeder and lineage rather than by the Permanent Marker name alone.

Permanent Marker vs. Wedding Cake, Gelato and Runtz

All four belong to the same modern era of dessert and candy genetics. What sets the Permanent Marker strain apart is the gas. It keeps the sweetness of its relatives but adds a sharp fuel note that the others mostly lack. Browse our Wedding Cake, Gelato and Runtz listings to compare.

How to Spot Authentic Permanent Marker Seeds

A Strain of the Year award brings a wave of copies. A few habits help buyers find real Permanent Marker seeds:

1. Check the breeder name. The original line is credited to Seed Junky Genetics; other breeders’ versions should say what they are.
2. Read the lineage. A real Permanent Marker pack should list Biscotti, Sherb Bx and Jealousy, or explain how the version differs.
3. Buy sealed, original breeder packaging with no signs of repacking.
4. Be careful with listings that lean only on the award or the name and say nothing about the source.

A Short Timeline of the Permanent Marker Strain

Exact release dates for modern exotics are rarely published, so this timeline follows how the story is usually told rather than documented launch dates.

The Numbered Gelato Cuts in Permanent Marker

Two of the three parents in the Permanent Marker strain carry a numbered Gelato cut. Gelato was released in the Bay Area in the 2010s, and growers kept individual selections under numbers, such as Gelato #25, Gelato #33 and Gelato 41. Each number refers to one specific plant chosen from the original seed run.

Biscotti traces to Gelato #25, which is usually described as sweeter and more doughy. Jealousy traces to Gelato 41, which is usually described as gassier and sharper. Having both in the Permanent Marker strain helps explain how it manages to be both sweet and gassy.

Numbered cuts like these are why buyers care about exact lineage. Two strains can both say Gelato in their family tree and still smell very different depending on which cut was used.

The West Coast Exotic Scene

The Permanent Marker strain came out of a particular moment in West Coast cannabis. In the 2010s, breeders and growers in California focused on exotic flower: loud, unusual aromas, colorful buds and heavy frost, sold under memorable names in eye-catching packaging.

The Cookies family from the Bay Area provided much of the raw material for that movement, and California breeders like Seed Junky Genetics refined it into new lines. Permanent Marker is one of the clearest results of that era, and one of the few exotics from it to win a major national award.

Our review of Girl Scout Cookies covers the family’s starting point.

Reading a Permanent Marker Seed Listing

When you look at Permanent Marker seeds, the listing should tell you a few things clearly:

• Breeder: who made the cross, since several breeders now offer versions.
• Seed type: feminized, regular or autoflower. Our explainer on feminized vs. regular seeds covers the difference.
• Lineage: the original Biscotti x Sherb Bx x Jealousy cross, or a newer cross that uses Permanent Marker as one parent.
• Generation terms: labels like S1, F1 or Bx describe how the seed was made. See our guide to S1, F1 and F2 seeds.

If a listing is vague on all of these, treat it with caution.

Common Myths About the Permanent Marker Strain

• Doja Pak bred it. Doja Pak is the brand most associated with the flower; the genetics are credited to Seed Junky Genetics.
• Every Marker strain is Permanent Marker. Some Marker-named lines are crosses of Permanent Marker, and some simply borrow the word. Check each lineage.
• Higher THC means a better pack. Reported THC describes mature flower and varies widely by sample. It says little about the quality or authenticity of seeds.
• All seeds in a pack are identical. Even feminized seeds from a three-way cross can show different expressions.
• The award makes every listing authentic. The award belongs to the strain, not to any particular pack. Provenance still matters.

Permanent Marker and the Return of Gas

Through much of the 2010s, the most hyped strains leaned sweet: cookies, cake, gelato and candy. By the early 2020s, many buyers were looking for something sharper again, the kind of fuel and funk that older lines like Chemdog, Sour Diesel and OG Kush were known for.

The Permanent Marker strain answered that demand without leaving the dessert family behind. It kept the creamy, fruity base of its Cookies and Gelato relatives and added a loud gas note on top. That is a big part of why it caught on so quickly, and why so many newer lines now try to combine sweet and gas in the same way.

Week 9: Harvest Decision

• Trichomes: Look for 70% milky, 20% amber, 10% clear
• Pistils: 80% should be brown/orange
• Flush: Begin 7-10 day plain water flush
• Final Check: Calyxes should be swollen, almost bursting

🌾 Harvest & Curing Guide

⏰ Perfect Harvest Timing

Visual Indicators:

• Trichomes: 70% milky white, 20% amber, 10% clear
• Pistils: 80% brown/orange, curled inward
• Calyxes: Fully swollen, “pregnant” appearance
• Fan Leaves: Natural yellowing and dying off

Aroma Indicators:

• Peak terpene production just before amber trichomes appear
• Maximum fuel/sweet balance – if waiting longer, sweetness may diminish
• Room-filling scent even through carbon filters

🔪 Harvest Process

Preparation:

• 48-72 hour darkness before harvest (optional but recommended)
• Sharp, clean trimming scissors – resin will gum up tools quickly
• Gloves essential – this strain is incredibly sticky
• Good ventilation – strong aroma during processing

Wet vs. Dry Trimming:

• Wet Trim: Better for dense buds, prevents mold
• Dry Trim: Preserves terpenes better, slower process
• Our Recommendation: Wet trim for Permanent Marker due to density

🌬️ Drying Protocol

Optimal Conditions:

• Temperature: 60°F to 65°F (15-18°C)
• Humidity: 55% to 62% RH
• Airflow: Gentle circulation, avoid direct fans on buds
• Light: Complete darkness – light degrades THC and terpenes
• Duration: 10-14 days until small stems snap cleanly

Drying Setup:

• Hang whole branches or individual buds on lines
• Space adequately – dense buds need air circulation
• Monitor daily – Permanent Marker’s density can trap moisture
• Test doneness: Outer buds feel dry, stems snap with slight bend

🏺 Curing for Maximum Potency

The Critical Phase: Curing is where Permanent Marker truly shines. The complex terpene profile develops incredible depth with proper curing.

Curing Timeline:

Week 1:

• Jar Burping: 15-30 minutes daily
• Humidity: 58% to 62% (use Boveda packs if needed)
• Changes: Harsh chlorophyll taste diminishes

Week 2-4:

• Jar Burping: Every 2-3 days for 15 minutes
• Humidity: Maintain 58% to 62%
• Changes: Terpenes merge and develop complexity

Month 2-3:

• Jar Burping: Weekly 15-minute sessions
• Peak Flavor: Fuel and sweet notes perfectly balanced
• Peak Potency: THC conversion complete

Month 4-6:

• Maintenance: Monthly check-ins
• Premium Quality: Connoisseur-level smoke
• Storage: Can maintain quality for more than 12 months properly stored

Pro Curing Tips:

• Glass jars only – plastic affects terpene profiles
• Fill jars 75% – leave room for air exchange
• Grove Bags work well as alternative to jars
• Cool, dark storage – basement or wine fridge ideal
• Track humidity – 62% Boveda packs are perfect

Questions to Ask Before Adding Permanent Marker Seeds

1. Who is the breeder, and is the original Seed Junky Genetics cross or a newer version?
2. Is the lineage listed in full, with Biscotti, Sherb Bx and Jealousy?
3. Is the pack feminized, regular or autoflower, and is that what you want for your collection?
4. Is it sealed, original breeder packaging from a seller who can explain where it came from?
5. Do you have somewhere cool, dark and dry to store it, away from children and pets?

If the answer to each question is clear, you are looking at a pack worth adding.

Why the Permanent Marker Strain Matters

Every few years, a strain comes along that changes what people expect cannabis to smell like. Skunk did it in the 1970s, OG Kush did it in the 1990s, and Girl Scout Cookies and Gelato did it in the 2010s. The Permanent Marker strain is one of the strains that defined the early 2020s.

It showed that the dessert era did not have to give up gas, and it gave Seed Junky Genetics another landmark line. For buyers, that history is the reason Permanent Marker seeds belong in any serious modern collection.

Building a Seed Junky Collection

The Permanent Marker strain makes a strong centerpiece for a collection built around Seed Junky Genetics. A natural set would include Permanent Marker alongside Wedding Cake, Kush Mints and Jealousy, which together show how one breeder shaped a decade of exotic genetics.

To show the wider family, add a Biscotti pack and a Sunset Sherbet line, the other two parents. For a high-potency theme, see our high-THC seeds collection, keeping in mind that THC figures describe mature flower, not seeds.

Storing Permanent Marker Seeds in a Collection

Keep Permanent Marker seeds in their sealed original pack, somewhere cool, dark and dry, and out of reach of children and pets. Avoid heat, sunlight and humidity, all of which age seeds faster.

Keep the receipt and any breeder paperwork with the pack. For a line this widely copied, proof of where your Permanent Marker seeds came from is part of their value.

Seeds, the Law and Our Rules

Cannabis laws differ by state, and federal hemp and seed rules are changing under Section 781. Check the law where you live before you buy anything. Our cannabis seeds by state guide links every state and its official sources, and our explainer on what Section 781 is covers the federal side.

Every buyer must be 21 or older. We sell seeds only to adults 21+.
