LA Ultra
aka Lau, L.A. Ultra, Los Angeles Ultra
LA Ultra is an 80/20 indica-dominant hybrid created by Resin Seeds through crossing LA Confidential with MK Ultra. With THC levels reaching 19-28% and a myrcene-rich terpene profile, this strain delivers profound euphoria followed by deep, sedative body relaxation. The complex flavor combines earthy pine, bright citrus, and diesel fuel notes. Perfect for evening use, LA Ultra excels at promoting sleep, relieving pain and anxiety, and inducing powerful couch-lock effects that seasoned consumers crave.
The Short Answer
What kind of high is LA Ultra?
Myrcene-led and earthy on the palate, most often reported relaxed and picked for sleep & bedtime at night.
Terpenes decide how a strain feels — THC% only decides how strong the dose is. Here is the family, the chemistry behind it, and what people reach for it to do.
Terpenes are the aromatic compounds that shape the character of a high. The blend a strain carries — not its THC percentage — is what makes one feel bright and social and another heavy and sleepy, which is why the top three are listed rather than just the leader.
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.

The Experience
Professor High Says...
In-depth strain breakdown from Professor High, our AI cannabis expert
Settles into the couch with a satisfied exhale
Okay, so here's what's happening right now with LA Ultra coursing through my system. The initial rush came on smooth—this gentle euphoric wave that just lifted all the mental weight I'd been carrying. My mind feels light but not scattered, more like... crystallized clarity where thoughts flow easily but nothing feels urgent or stressful.
What's fascinating from a neurochemical perspective is how that myrcene-dominant profile is absolutely flexing its muscle-relaxing properties. I can feel this tingling cascade that started at my shoulders and just kept traveling downward, releasing tension I didn't even know I was holding. My body feels like it's melting into the furniture in the most therapeutic way possible—it's that classic indica gravitational pull that makes you completely content to remain motionless.
The limonene is doing work too—there's this underlying brightness preventing the experience from becoming too heavy or sedating too quickly. I'm still engaged, still present, just incredibly comfortable and happy. This is textbook indica dominance meeting minor sativa influence: profound physical relaxation wrapped in mental contentment. Around the 45-minute mark now, and the sedative qualities are definitely intensifying. This is premium evening medicine, folks.

Introduction: The West Coast Powerhouse
LA Ultra stands as a testament to modern cannabis breeding excellence, combining two legendary West Coast genetics into a powerhouse indica-dominant hybrid that has captured the hearts of cannabis connoisseurs worldwide. Created by Resin Seeds in the early 2010s, this 80% indica / 20% sativa hybrid masterfully marries LA Confidential with MK Ultra, resulting in a strain that delivers profound relaxation wrapped in a euphoric embrace. With THC levels ranging from 19-28% and minimal CBD content (0.1-1%), LA Ultra has earned its reputation as a premium evening strain celebrated for its sedative properties and complex flavor profile.
🧬 Genetic Heritage & Lineage
LA Ultra's pedigree reads like cannabis royalty. By crossing LA Confidential (itself a legendary OG Kush descendant) with MK Ultra (a potent indica known for its hypnotic effects), Resin Seeds created a synergistic combination that amplifies the best qualities of both parents. LA Confidential contributes smooth, piney OG characteristics and deep relaxation, while MK Ultra brings intense sedative properties and a unique terpene complexity. This union produces a strain that honors West Coast cannabis tradition while delivering a distinctly modern, narcotic-level relaxation that has earned LA Ultra recognition including Cannabis Cup awards in 2014.
👃 Terpene Profile & Aromatics
LA Ultra's terpene profile is dominated by myrcene (1.2%), the sedating terpene responsible for the strain's couch-locking body effects. Supporting players include limonene (0.8%), which adds citrus brightness and mood elevation, pinene (0.6%) for mental clarity and focus, caryophyllene (0.5%) contributing spicy notes and pain relief through CB2 receptor activation, and humulene (0.4%) rounding out the profile with earthy, anti-inflammatory properties. This 3.5% total terpene content creates a complex aromatic experience that unfolds in layers.
The aroma opens with pungent earthy notes grounded by rich soil and forest floor, immediately followed by bright citrus and pine that cut through the heaviness. As you break apart the dense buds, you'll discover spicy herbal undertones mixed with fruity sweetness and subtle diesel fuel accents. Some phenotypes express unique floral and even chemical notes that add intrigue to the bouquet. The scent is simultaneously grounding and uplifting, preparing you for the multifaceted experience to come.
👅 Flavor Experience
LA Ultra's flavor journey mirrors its aromatic complexity with delightful precision. The initial inhale delivers earthy sweetness with pronounced pine and citrus, particularly lemon-lime brightness that dances on the palate. Mid-palate, you'll notice spicy herbal notes emerge, often described as having diesel or kushy characteristics that classic OG fans will recognize. Some users detect berry and fruity undertones that add sweetness to balance the fuel-forward profile.
The exhale is where LA Ultra truly shines, leaving a lingering combination of sweet earth, chemical sharpness (in the best way), and herbal spice that coats the mouth. The aftertaste carries notes of lime zest and pine resin, with that signature OG fuel finish that experienced consumers crave. This complex flavor profile makes LA Ultra equally enjoyable through smoking, vaping, or concentrate consumption.
🎯 Effects & Experience
LA Ultra's effects build gradually, typically taking 10-15 minutes to fully manifest. The experience begins with a wave of euphoria that washes over the mind, bringing happiness, mental uplift, and often bursts of creativity and giggly sociability. You'll notice a sense of calm contentment settling in, relieving mental tension and quieting racing thoughts.
As the cerebral effects plateau, LA Ultra's 80% indica genetics take command of your body. A tingling sensation often starts at the crown and cascades downward, releasing muscle tension and promoting profound physical relaxation. This isn't a sudden crash but rather a gentle descent into deep bodily comfort. Many users report feeling heavy and content to remain stationary, making this a classic couch-lock strain.
The peak effects last 2-3 hours, with powerful sedative qualities that make LA Ultra ideal for evening use. As the experience winds down, most users transition naturally into deep, restful sleep. The hunger-inducing properties kick in mid-session, so have snacks prepared. With higher doses (especially in the 25-28% THC range), expect more narcotic-level sedation suitable only for experienced consumers.
💚 Medical & Therapeutic Potential
LA Ultra's therapeutic profile is impressive, particularly for sleep disorders and anxiety management. The high myrcene content combined with substantial caryophyllene creates potent analgesic effects that may help with chronic pain, neuropathic pain, inflammatory conditions, arthritis, fibromyalgia, muscle spasms, and cramps. The CB2 receptor activation from caryophyllene specifically targets pain pathways.
For mental wellness, LA Ultra may help manage stress, anxiety disorders, PTSD symptoms, and depression through its uplifting onset followed by deep relaxation. The sedative qualities make it particularly effective for insomnia and sleep disturbances. Additionally, the strain's appetite-stimulating properties may benefit those dealing with appetite loss or nausea.
👁️ Visual Characteristics
LA Ultra produces dense, resinous buds with a distinctive appearance. The flowers display deep forest green primary coloration often accented by purple undertones that emerge in cooler growing conditions. Fiery orange to rust-colored pistils weave throughout the bud structure, creating striking contrast against the green backdrop. A thick blanket of amber and crystalline trichomes coats every surface, giving buds a frosty, sticky appearance that immediately signals potency.
📜 Cultural Context & Consumer Considerations
LA Ultra represents the evolution of West Coast cannabis breeding, honoring OG Kush lineage while pushing potency boundaries. The strain's Cannabis Cup recognition in 2014 cemented its status among elite cultivars. Today, LA Ultra remains commonly available at dispensaries, particularly in California and other mature markets.
Best suited for evening and nighttime use, LA Ultra is ideal for experienced consumers comfortable with potent indica effects. Novice users should start with very small doses due to the high THC content and powerful sedative properties. This strain excels for unwinding after stressful days, managing chronic pain, promoting deep sleep, or simply enjoying profound relaxation with close friends in comfortable settings.
