Quick Hits
What kind of high is Louis XIII?
An indica-dominant hybrid reported as relaxed, sleepy and happy. Picked for meditation and sleep & bedtime at night. The profile features sweet pine flavor, skunky pine aroma and myrcene as the lead terpene.
Terpenes help give cannabis its aroma. Compare citrus, pine and earthy notes to find what appeals to you. The profile offers clues, not a guaranteed high.
Terpene percentages belong to the jar, not the strain. They move with harvest timing, drying, cure and shelf age — the lighter ones literally evaporate. What holds steady is which terpenes lead, so that is what we rank.

There’s more to a strain than THC%.
THC percentage is a property of the product in your hand, not of the strain. It shifts with the batch, the grower, the harvest, and how the flower was cured and stored — the same strain can test several points apart from two different jars.
Treat the ranges below as market context for what to expect on a shelf — then read the actual label on the product you are buying, and use the terpene profile to judge how it will feel.

Professor High interprets the pattern
I just took a few hits of Louis XIII and — let me tell you — this is exactly what that OG Kush lineage is supposed to feel like when it's done right. There's this initial warm cognitive brightness that spreads across my forehead like someone turned a dimmer switch to the perfect setting. My thoughts feel simultaneously expansive and unhurried — like I have all the ideas and absolutely zero urgency about them, which is genuinely pleasant.
Then, maybe 15 minutes in, the indica genetics from LA Confidential start doing their work. There's a gravitational quality to the body effect — not a crash, more like a gentle, insistent invitation to stop holding yourself so rigidly. My shoulders dropped about two inches without me even deciding to relax them. That's the myrcene doing its sedating thing alongside caryophyllene working on the physical tension.
The euphoria is sustained and warm — happy without being giddy, relaxed without being checked out. And yes, I'm absolutely about to find something to eat. The munchies on this one are real and unapologetic. Perfect evening strain. Science agrees.

The helpful detail
Louis XIII: The Cannabis Royalty
Louis XIII — also known as King Louis, King Louie, or King Louie XIII — is one of cannabis culture's most regal and celebrated strains. This indica-dominant hybrid (70% Indica / 30% Sativa) carries itself with the authority its name implies, delivering a deeply immersive experience that has earned it a devoted following from California dispensary shelves to cannabis cups worldwide. If you're looking for a strain that commands respect in both potency and complexity, Louis XIII belongs on your shortlist.
🧬 Genetic Heritage & Lineage
Louis XIII descends from two of cannabis royalty's most iconic parents:
- OG Kush — the legendary West Coast backbone responsible for the strain's cerebral euphoria, complex terpene profile, and unmistakable fuel-meets-earth aroma
- LA Confidential — the sleek, smooth indica that contributes deep physical relaxation, sedating body effects, and those classic pine-forward flavors
Bred by Zamnesia Seeds, this cross marries the best of both worlds: OG Kush's euphoric cerebral lift with LA Confidential's full-body tranquility. The result is a strain that hits hard but lands smooth — royally so.
👃 Terpene Profile & Aromatics
Louis XIII's terpene profile reads like a who's who of powerhouse compounds:
| Terpene | Role | Aromatic Contribution |
|---|---|---|
| Myrcene (dominant) | Sedating, body-relaxing | Earthy, musky, herbal foundation |
| Limonene | Mood-lifting, stress-relieving | Bright citrus, lemon zest top notes |
| Caryophyllene | Pain relief, CB2 activation | Spicy, peppery warmth |
| Pinene | Mental alertness, focus | Sharp pine, forest freshness |
| Humulene | Anti-inflammatory | Subtle woody, hoppy undertones |
| Linalool | Calming, sleep-support | Soft floral whisper |
The nose on Louis XIII is immediately striking — a pungent, dank opening wave of earthy pine and skunk, layered with sweet citrus brightness and spicy diesel depth. As buds warm up, musky and woody undertones emerge, rounding out what is a genuinely complex aromatic experience.
👅 Flavor Experience
On the inhale, you'll encounter bold pine and earthy wood with a spicy kick from caryophyllene. The mid-palate opens up into sweet citrus and lemon, a nod to the limonene content. The exhale carries a satisfying diesel-meets-herbal finish with lingering spice. The overall flavor journey is rich, layered, and unmistakably Kush-forward — each puff revealing new dimensions.
🎯 Effects & Experience
Louis XIII's effects are as commanding as its name. Onset arrives within minutes, beginning with a warm cerebral euphoria that lifts mood and sparks a gentle creative awareness. You'll feel happy, uplifted, and mentally at ease — the sativa genetics from OG Kush doing their initial work.
As the experience deepens (typically 15–30 minutes in), the indica dominance takes over: a heavy, full-body relaxation cascades from head to shoulders to limbs, melting tension with impressive efficiency. The peak is characterized by deep sedation, a pleasant couch-lock quality, and for many users, a substantial increase in appetite. Duration typically runs 2–4 hours, transitioning naturally into sleepiness — making this an ideal evening closer.
🎮 Use Cases & Activities
Louis XIII shines brightest in these scenarios:
- Unwinding after demanding days — the stress-dissolving body effects are exceptional
- Creative brainstorming sessions before the sedation fully sets in
- Pre-sleep rituals for those struggling with rest
- Appetite stimulation during low-appetite periods
- Pain and tension management in a social or solo setting
💚 Medical & Therapeutic Potential

- Chronic pain and muscle spasms — caryophyllene and myrcene work synergistically on physical tension
- Insomnia — the sedating myrcene-linalool combination promotes deep rest
- Stress and anxiety — limonene and linalool contribute calming, mood-stabilizing properties
- Depression — the euphoric onset may lift mood and provide temporary emotional relief
- Appetite stimulation — classic indica munchies, useful for appetite-loss conditions

It became a California cannabis staple and is widely available at dispensaries across legal markets.
