XJ-13

Why you should buy XJ-13 seeds

There’s something undeniably special about a strain that makes you feel like you could take on the world, and have a laugh while doing it. That’s exactly what XJ-13 brings to the table. A sativa-leaning hybrid with a seriously cheerful vibe, this one’s loved for its creative spark, uplifting energy, and sociable edge. Perfect for morning tokes, brainstorm sessions, or just catching up with mates.

Plus, with high yields, robust genetics, and a terpene profile that smells like a pine grove dipped in fruit salad, XJ-13 isn’t just fun to smoke. It’s a joy to grow.

Strain Overview

Origin

XJ-13 is the lovechild of two absolute powerhouses: Jack Herer and G13. Jack brings the cerebral zip, that energizing sativa clarity it’s famous for. G13 adds a mellow, indica foundation that smooths everything out. The result? A well-balanced hybrid that leans slightly sativa but never overwhelms. It’s been a cult classic among West Coast connoisseurs for years, and for good reason. This one’s as comfortable in a head stash as it is on a grower’s "repeat" list.

Effects & flavours

XJ-13 is a bright and bubbly high that hits quickly, usually with a wave of euphoria and a rush of ideas. It’s the kind of strain that makes music sound better, conversations flow, and mundane tasks oddly satisfying. Energetic, creative, and talkative, without tipping over into chaos.

flavour-wise, it’s a walk through a citrus grove with a pine forest not far behind. Expect notes of sweet fruit, earthy undertones, and a cool minty finish. It’s refreshing, balanced, and lingers on the palate in the best way.

THC & CBD Levels

With 22% THC and 0.5% CBD, this strain delivers enough punch to satisfy experienced users while staying approachable for beginners. It’s strong, sure, but not in the "forget where you put your keys" kind of way. More like "suddenly have a great idea for a screenplay" strong.

Terpenes

The terpene lineup here is as vibrant as the high itself. Terpinolene brings that sharp citrusy sparkle, while myrcene gives it a grounding, herbal earthiness. Caryophyllene adds a gentle peppery kick. Linalool softens it with floral calm, and limonene wraps it all in a fresh citrus zest. Together, they create a profile that’s both uplifting and grounded. A little like the high.

Growing XJ-13 Seeds

Grow Difficulty

Beginner-friendly and generally low-maintenance, XJ-13 grows with the kind of cooperative attitude cultivators dream of. It’s resilient, responds well to training, and handles environmental fluctuations without throwing a tantrum. Great for first-timers, but rewarding enough for experienced growers to enjoy too.

Indoor vs. Outdoor Growing

XJ-13 adapts beautifully to most environments: indoor setups, sunny balconies, greenhouses, you name it. Indoors, it stays within a manageable 80 cm to 150 cm, perfect for tents or small rooms. Outdoors, it can stretch a bit more (up to 190 cm if conditions are right) but never gets out of hand. Its high resistance to mould makes it an excellent pick for slightly more humid or unpredictable climates, especially in temperate or mountain regions.

Flowering Time & Yield

Expect flowering to take around 63 to 70 days. Indoors, she’ll reward your efforts with generous yields of 450 to 650 gram per m2. Outdoors, you’re looking at 550 to 800 gram per plant. That’s plenty of sticky, citrus-scented bud to keep your jars full for a while.
