Permanent Marker by Advanced Seeds

Permanent Marker Strain Info

Permanent Marker is not just another hype strain—this one carries the weight of legends in its DNA and the punch of a heavyweight in every puff.

Born from a bold cross between (Sherb Bx x Biscotti) and Jealousy, this strain reflects the cream of the Californian cannabis crop, originally crafted by Seed Junky Genetics and made iconic by Doja Pak.

What you get is a fusion of sweet dessert funk, minty spice, and raw diesel fumes, wrapped in a smoke so flavorful it feels like licking battery acid off a candy cane—if that was somehow a good thing.

This is a strain that doesn’t just knock, it kicks the door in with 30–34% THC, making it one of the most potent feminized cannabis seeds you’ll ever grow.

Expect dense, sticky buds dripping with milky trichomes, each one looking like it’s been dipped in frost and glazed with resin.

Permanent Marker grows like it knows it’s a star—compact and bushy indoors (around 70–90 cm / 2.3–3 ft) and stretching tall outdoors up to 2.6–2.9 meters (8.5–9.5 ft) with vigor and elegance.

Its leaves flash a lime green so loud it could stop traffic, providing the perfect backdrop for its bulbous, terp-saturated colas.

Flowering Time & Yield

Get ready for results fast—this strain wraps up its bloom in just 60 to 65 days, no dragging its feet here.

When grown indoors, it delivers a hefty harvest of 550–600 grams/m² (19.4–21.2 oz/yd²), satisfying even the most demanding growers.

Take it outdoors, and you’ll be grinning by mid to late October as she rewards you with a serious bounty and colas as long as your forearm.

Effects and Aroma

The first hit is like getting socked in the brain with a velvet glove—an intense cerebral rush that flips your creativity switch and leaves you grinning like you just heard the best joke of your life.

Then, just when you’re soaring, a warm, heavy blanket of deep body relaxation slides in and anchors you down without shutting off your mind.

It’s the kind of balance that turns a session into an experience—psychedelic euphoria up top, soothing calm down below.

The smell punches out of the jar with sharp diesel fumes, crushed mint leaves, and a sprinkle of pepper, before finishing with the sweetness of warm cookies fresh from a stoner’s oven.

Light it up, and the room fills with a funky, gassy, floral-cloud vibe that lingers in the air and on your taste buds long after the joint’s gone.

This is not your grandma’s weed—unless she rides Harleys and does dab hits at breakfast.

Growing Tips & What Stands Out

If there’s one thing that grabs our attention every single time, it’s how Permanent Marker manages to look like an exotic boutique strain while growing like a beast that’s been training in the wild.

It thrives in warm, Mediterranean-style climates but handles cooler nights surprisingly well, especially during the final stretch of flowering.

This strain doesn’t just look strong—it really is, showing solid resistance to common pests and mold, even in more humid environments.

We recommend keeping the airflow steady and using low-stress training or lollipopping to open up the dense canopy and let those lower buds soak up the light.

She’s hungry for light and nutrients, especially in bloom, so don’t be shy with a balanced feeding schedule if you want those buds swollen and sticky.

Despite her elite genetics, she’s not high-maintenance—medium difficulty with a strong payoff, perfect for growers who want a little challenge and a lot of reward.

Permanent Marker is one of those strains that makes you feel proud when harvest time rolls around—not just for the yield, but for growing something that looks and smells this damn good.
