Gridlock
Also known as Glk, Granddaddy Purple
Gridlock is a balanced 50/50 hybrid from Wizard Trees, bred from True OG and Zangria. It leads with a sweet, pungent diesel nose layered with berry, citrus, pine and spice. The rare Delta-3-Carene-dominant terpene profile backs it up. Effects open with euphoria and a happy lift, then settle into deep relaxation, sleepiness and couch-lock. That makes Gridlock a go-to choice for evening wind-downs and bedtime. Read more Show less
Quick Hits
What kind of high is Gridlock?
A balanced hybrid reported as relaxed, sleepy and euphoric. Picked for sleep & bedtime and evening wind down in the evening. The profile features fruity diesel flavor, pungent diesel aroma and carene 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.

Batch context Complete cannabinoid record
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
First comes a sweet diesel flavor, then a ripple of berry and pine on the exhale. Within minutes, my mood climbs. It's a warm, euphoric glow that makes everything feel softly amusing, and for a while my thoughts wander into creative little detours. Then the second act arrives. A heavy, melting relaxation pours down from my shoulders and pools in my legs. The name suddenly makes sense: I'm in gridlock, happily parked on this couch, and no amount of honking is moving me. Scientifically, I suspect that myrcene and linalool are teaming up with a hefty THC load to dim my nervous system's dashboard lights. Meanwhile, caryophyllene is quietly working on CB2 receptors to smooth out the aches. The carene adds a crisp, forest-like sweetness that keeps the experience feeling clean rather than muddy. My eyelids are getting delightfully heavy. This is not a strain for answering emails. It's a strain for a warm blanket, a good film and an early, deep sleep.

The helpful detail
Gridlock: The Evening Heavyweight from Wizard Trees
Gridlock is a balanced hybrid (about 50% indica / 50% sativa) bred by Wizard Trees from a cross of True OG and Zangria. It emerged in the 2010s and is now commonly available. The name fits: once this strain settles in, your evening tends to come to a pleasant standstill. It's a Type I chemovar, which means it is THC-dominant with very little CBD.
Potency
- THC: 14.5%–30%. This is a wide reported range, so the specific batch matters. Check the label before you dose.
- CBD: 0.05%–0.66%. That's too low to meaningfully soften the THC.
At the top of that range, Gridlock is firmly in high-potency territory.
👃 Terpene Profile
Gridlock stands out because its lead terpene is Delta-3-Carene, which is unusual in a market dominated by myrcene and caryophyllene. The reported profile totals roughly 1%:
- Delta-3-Carene (0.25%): sweet, piney and earthy. It drives much of the forest-like backbone.
- Caryophyllene (0.12%): peppery spice. It binds to CB2 receptors, which is why it's studied for body comfort.
- Myrcene (0.11%): earthy and musky. It's widely associated with sedating, heavy-body effects.
- Alpha-Phellandrene (0.11%): a bright, peppery-herbal accent.
- Linalool (0.09%): floral and associated with calm and sleep support.
- Sabinene (0.09%), Camphene (0.08%), Nerolidol (0.06%), Pinene (0.05%) and Limonene (0.03%): these round out the woody, spicy and faintly citrus edges.
Terpene data across sources is mixed, so expect some batch-to-batch variation.
Aroma & Flavor
The nose is pungent diesel layered over sweetness.
- Aroma: diesel, pungent, sweet, earthy, fruity, pine and spicy
- Flavor: sweet, diesel, fruity, earthy, citrus, berry, spicy and pine
On the inhale, you'll typically taste sweet fuel. As it develops, berry and citrus fruit come through. The exhale finishes earthy, piney and spicy, a pairing that tracks with the carene, caryophyllene and myrcene in the profile.
🎯 Effects & Experience
Reported effects fall into two waves:
- Euphoric, happy and uplifted: a warm mood lift that can spark some creative thinking
- Relaxed and sleepy: users frequently describe couch-lock and full-body sedation
The balanced genetics show up in that early lift. On balance, though, Gridlock is a wind-down strain, and higher doses push it firmly toward sleep.
Best Uses
Gridlock is best suited to the evening:
- Sleep & Bedtime
- Evening Wind-Down
- Watching TV & Movies
- Baths & Showers
- Eating
💚 Medical & Therapeutic Potential
Anecdotal reports suggest Gridlock may help with:
- Insomnia: its sedating finish may support sleep onset
- Pain: THC plus caryophyllene may ease physical discomfort
- Muscle tension: the heavy body relaxation may help
- Stress and anxiety: linalool and myrcene may contribute to the calm
- Low mood: the euphoric early phase may offer some relief
- Low appetite: it may encourage hunger
- Inflammation: it may ease inflammation tied to conditions like arthritis
Consult a healthcare provider before using cannabis medically.
⚠️ Consumer Considerations
- With THC reaching 30%, Gridlock suits experienced consumers best. Newcomers should take very small amounts.
- Expect couch-lock, so don't plan anything demanding afterward.
- Common cannabis side effects such as dry mouth and dry eyes apply.
