Permanent Marker Auto Cannabis Seeds
Permanent Marker Auto is an indica-dominant autoflowering cannabis seed that descends from the 2023 Strain of the Year. A cross of Permanent Marker and Ruderalis, it carries roughly 75% indica and 25% sativa genetics — delivering that heavy, resinous Permanent Marker character in a compact, light-cycle-independent plant. If you want the pungent, marker-pen funk without fussing over photoperiods, this is where you start.

Flavour and Aroma Profile of Permanent Marker Auto
Permanent Marker Auto smells exactly like its name suggests — sharp, chemical, unmistakably funky, like cracking open a fresh Sharpie in a closed room. Underneath that initial hit, you get floral and soapy notes layered with sweet candy and a gassy, fuel-like undercurrent. It is not subtle, and that is entirely the point.
The dominant terpenes tell the story. Myrcene leads at around 30%, bringing herbal, earthy sweetness. Limonene follows at 20%, adding citrus brightness that lifts the heavier notes. Caryophyllene rounds things out at 15% with a peppery, slightly spicy edge. Together they create a profile that is sugary and citrusy on the inhale, with that distinct gassy bite on the exhale. We've had customers open a bag in the shop and people two aisles over notice it. Fair warning: this one fills a room.
Terpene Breakdown
| Terpene | Proportion | Character |
|---|---|---|
| Myrcene | 30% | Herbal, earthy, sweet — the foundation |
| Limonene | 20% | Citrus, bright, uplifting |
| Caryophyllene | 15% | Peppery, spicy, warm |
Genetics Behind Permanent Marker Auto
Permanent Marker Auto carries the genetics of the original Permanent Marker — the strain that took home Strain of the Year honours in 2023 — crossed with Ruderalis to introduce autoflowering capability. The result is a 75% indica / 25% sativa hybrid that flowers based on age rather than light schedule changes.
The original Permanent Marker built its reputation on potency and that unmistakable marker-pen terpene profile. Adding Ruderalis genetics doesn't dilute the character as much as you might expect — it mostly shortens the lifecycle and removes the need for 12/12 light flipping. You still get the heavy indica lean, the dense flower structure, and that loud, funky aroma. The sativa quarter keeps things from going completely couch-lock, adding a spark of mental activity to the physical weight.

Growing Permanent Marker Auto Seeds
Permanent Marker Auto is an autoflowering strain, which means it transitions from vegetative growth to flowering on its own internal clock — no need to adjust your light schedule to 12/12. That makes it a strong pick for growers who want simplicity or who are running a tent alongside photoperiod plants on 18/6 or 20/4 lighting.
- Germinate your Permanent Marker Auto seeds using the paper towel method or directly in a small pot of moist, airy substrate. Taproots typically emerge within 24–72 hours.
- Transplant seedlings into their final container early — autos don't love being repotted mid-grow. A 10–15 litre fabric pot is a solid choice. Airy soil with perlite, or coco-perlite mixes, both work well.
- Run your lights at 18/6 or 20/4 from seed to harvest. Autos don't need a dark period to flower, so more light generally means more yield. Some growers run 24/0, though we'd give the plants at least a few hours of rest.
- Keep feeding moderate during veg — autos are smaller plants and burn easier than photoperiods. Increase nutrient strength gradually as flowering sets in. Grower reports suggest around 1,400 ppm in week four of flower works well for this strain.
- Watch for resin production on sugar leaves from early flower. Permanent Marker Auto tends to frost up quickly. Expect a fruity, funky smell to develop as trichomes mature.
- Harvest when trichomes shift from clear to milky with some amber — a jeweller's loupe or USB microscope is worth the few euros. The indica dominance means she'll likely finish compact and dense.
One honest note: autoflowers are less forgiving of early mistakes than photoperiods. If you stunt a photo plant, you can extend veg to recover. An auto just keeps ticking toward flower regardless. Get your environment dialled in before the seed goes in the soil, and you'll be rewarded.
Why Permanent Marker Auto Stands Out
We've sold a lot of autoflowering seeds since 1999, and the ones that stick around are the ones that actually deliver on flavour and potency rather than just convenience. Permanent Marker Auto earns its spot because the parent strain already proved itself — Strain of the Year in 2023 isn't a participation trophy. The auto version keeps that distinctive marker-pen terp profile intact while trimming the grow cycle down and removing photoperiod complexity.
Compared to something like a Northern Lights Auto — which is a solid, reliable, but fairly mellow smoke — Permanent Marker Auto brings a louder, more modern terpene profile. It is funkier, sweeter, and more complex. If Northern Lights Auto is a well-worn pair of trainers, Permanent Marker Auto is the pair that turns heads. Both have their place, but this one is for growers chasing flavour and bag appeal.
The indica-heavy genetics (75%) mean dense, compact buds with serious resin coverage. That 25% sativa keeps the mental side interesting — you are not just sinking into the sofa, there is a creative edge that the original Permanent Marker became famous for. Growers who've run this strain report sugar leaves coated in trichomes by week four of flower, with a fruity, gassy smell that builds as harvest approaches. If you don't have a carbon filter, your neighbours will know what you're growing.
Complete your setup: pair Permanent Marker Auto seeds with a carbon filter and extraction fan to keep that loud marker-pen aroma under control. A jeweller's loupe is also worth grabbing — you'll want to watch those trichomes develop on this one.
Frequently Asked Questions
What is Permanent Marker Auto?
Permanent Marker Auto is an autoflowering cannabis seed bred from Permanent Marker (2023 Strain of the Year) crossed with Ruderalis. It is 75% indica, 25% sativa, and flowers automatically without light schedule changes.
How does Permanent Marker Auto smell and taste?
Sharp marker-pen funk dominates, backed by floral, soapy, sweet candy, and fuel-like notes. Myrcene (30%), limonene (20%), and caryophyllene (15%) drive the profile — expect sugary citrus on the inhale and gas on the exhale. It is loud.
Is Permanent Marker Auto good for beginner growers?
Autoflowers are simpler than photoperiods since you skip the light-schedule switch. However, autos are less forgiving of early mistakes because you cannot extend veg to recover. Get your soil, pot size, and environment right from the start and you will be fine.
How long does Permanent Marker Auto take from seed to harvest?
Most autoflowering strains finish in 8–11 weeks from germination. Permanent Marker Auto's indica dominance typically means a compact growth cycle. Expect resin-coated sugar leaves by week four of flower.
What is the best light schedule for Permanent Marker Auto?
18 hours on, 6 hours off works well from seed to harvest. Some growers push to 20/4 for extra yield. We would give the plants at least a few hours of darkness — they seem to respond better with a brief rest period.
How does Permanent Marker Auto compare to the original Permanent Marker?
The auto version keeps the distinctive marker-pen terpene profile and indica-heavy effects of the original. The main difference is convenience: it flowers automatically and finishes faster. You trade some potential size and yield for a simpler, quicker grow cycle.
Does Permanent Marker Auto smell strongly during the grow?
Yes — intensely. The sharp, funky aroma develops early in flower and only gets louder. A carbon filter is not optional if discretion matters to you. This strain fills a room and then some.
