Black Amber Strain

Black Amber Strain: GMO Funk Meets OZ Kush Candy-Gas

The Black Amber strain is a modern funk-and-gas hybrid: GMO crossed with OZ Kush Bx2 by Fullmoon Genetics, then renamed and released to the wider world by Compound Genetics. It grows dark, heavy buds that can flash deep purple, smells like diesel and chemical funk with a sweet fruit edge, and delivers a calm, focused high that sinks into the body as it goes. It sits in the gassy, savory corner of the cannabis map — the same neighborhood as Garlic Breath and Donny Burger — and in our THCA flower collection the closest thing to it is a dark-fruit-and-gas hybrid.

It's also one of the more confused strains online. One popular guide says its parentage is unknown, another lists a completely different cross, and the potency numbers range from 18% to 32%. Below: the verified lineage and the name change, what it actually tastes like, how the high unfolds, how strong it really is, how to use it, how to grow it, and how to judge a bag.

Black Amber Strain Genetics & Lineage

• Type: Hybrid. Leafly calls it indica-dominant; AllBud lists it as an even 50/50. Reviewers describe a relaxed, body-forward high, so it plays indica-leaning.
• Ancestry: GMO × OZ Kush Bx2. Leafly writes the GMO parent as "GMO Cookies" — the same plant, also known as Garlic Cookies.
• Breeder: Fullmoon Genetics bred it; Compound Genetics renamed it Black Amber and built a seed line around it.
• THC: Leafly lists 21%; an Ontario retail listing (Be Humble) shows 25–31%; a UK medical listing is registered at 30%; AllBud says 30–32%.
• CBD: Under 1%.
• Aliases: BlA, BlAm — and, originally, High Fructose Corn Syrup.

The parents

GMO is a GSC (Girl Scout Cookies) × Chemdawg cross famous for its garlic, onion and fuel funk and its heavy, slow body. OZ Kush brings the other half: Leaf Magazines describes its "gassy, limey, candy, green bud" character. "Bx2" means the OZ Kush side was backcrossed twice, pulling the cross back toward OZ Kush's structure and candy-gas nose while GMO adds weight underneath.

From High Fructose Corn Syrup to Black Amber

According to Leaf Magazines' feature on the line, Full Moon Farms first named this cross High Fructose Corn Syrup. Compound Genetics renamed it Black Amber — a nod to a dark, sweet Japanese plum — then reversed its favorite phenotype, made pollen from it and bred it into Compound classics and newer hits, eight crosses in all, released as feminized seeds aimed partly at Germany's newly legal market.

Compound's head of marketing, Ruby Wagner, told the magazine she expected the GMO side to dominate: "I thought GMO was going to punch everything in the face." Instead, she said, "It just added a little back-end funk, body and weight." The first sellout from the line was Gastro Funk, Black Amber × Gastro Pop #5.

The lineage conflicts you'll see online

• "Unknown parentage": JointCommerce's long guide says no breeder has documented the cross. That's out of date — Leafly, AllBud, Leaf Magazines, an Ontario retail listing and a UK medical database all list GMO × OZ Kush Bx2.
• "Dark Knight × Purple Kush": Vivosun's grow guide lists this cross with no breeder. No other source we checked agrees; it may describe an older or unrelated line sharing the name.
• "OG Kush Bx2": the Ontario listing writes OG instead of OZ — almost certainly a typo for OZ Kush.
• High Fructose Corn Syrup: Leafly still lists it as a separate strain (GMO Cookies × OZ Kush bx2, Fullmoon Genetics), consistent with Leaf Magazines' account that it's the same cross under its original name.

Black Amber Terpene Profile

Leafly doesn't publish lab terpene data for Black Amber, so this comes from product listings. An Ontario listing names beta-caryophyllene, limonene and linalool; a UK medical listing names myrcene, limonene and caryophyllene as its major terpenes. Leafly's listing for the original High Fructose Corn Syrup name shows caryophyllene first, then limonene and linalool. Caryophyllene is the common thread — and the one terpene known to bind directly to the body's CB2 receptors, per a 2008 PNAS study.

• Caryophyllene: Pepper, spice and fuel — the backbone that GMO and Chemdawg-family strains share.
• Limonene: The sweet, limey candy note from the OZ Kush side, and part of why the high starts with a mood lift.
• Myrcene: Musky and earthy; it's the terpene most associated with the heavy body several reviewers describe.
• Linalool: A floral, lavender-like note that shows up in the "floral musk" some patients describe.

The cheese-and-chemical funk isn't one terpene — it's the GMO side's overall chemistry. Sweeter OZ-leaning cuts read limey and candied; GMO-leaning cuts read savory.

Appearance

The "Black" is earned. AllBud describes large, grape-shaped, dark olive-green nugs with deep amber undertones and reddish-orange hairs, under a coat of amber-tinted trichomes that make them look nearly black. Leafly reviewers report "very purple" buds with lots of orange hairs, and the Ontario listing notes green and purple hues. Leaf Magazines calls the Black Amber crosses "large and colorful." Cool nights late in flower push the purple further — a common trait in dark-colored cultivars.

Aroma and Flavor

Open a jar and the first hit is funk: diesel, chemical and a savory, cheesy edge from the GMO side. Underneath sits sweetness — fruit and lime-candy from OZ Kush. Leafly users list diesel, chemical and blue cheese as top flavors, and Leafly's description adds fruit. AllBud describes spicy, diesel, hashy and floral-kush aromas with a creamy, herbal-cheese flavor full of gas and spice. The Ontario listing sums it up as "GMO-dominant buds with hints of sweetness, funk, and earthiness."

One honest note from reviewers: the smoke can be harsh if the flower isn't cured well. A clean, slow cure and a lower-temp vape bring the sweetness forward.

Recreational Effects

Black Amber is a calm-first strain. On Leafly, where it holds a 4.7/5 rating from 30 reviews, the top-reported effects are:

• Relaxed: the headline effect — a strong, heavy body calm.
• Euphoric: a warm mood lift that arrives early.
• Focused: reviewers say the head stays settled rather than spacey or racy.
• Happy and giggly: reported by a smaller group, especially in social settings.

Reviewers repeatedly mention that it relaxes them without racing thoughts. One wrote, "Harsh smoke but deep relaxation and no paranoia"; another said it "doesn't give me high anxiety like other strains do." One compared the body effect to Bubba Kush without the heavy sleepiness. AllBud's write-up leans more creative — focus first, mild body relaxation after — while a UK medical listing reports tired, sedated and relaxed. The difference is mostly dose and phenotype.

How the high unfolds: onset, peak and duration

• First 5 minutes: a quick mood lift and a loosening across the shoulders.
• 15–60 minutes: the peak — calm, euphoric and quietly focused, good for music, a movie or a slow project.
• 1–3 hours: the body gets heavier. At higher doses, or late at night, it turns sleepy.

Most people treat it as an after-work or evening strain.

How Strong Is Black Amber?

Black Amber is a strong strain, but the numbers swing more than most:

• Leafly: 21% THC.
• Ontario retail (Be Humble): 25–31% THC, labeled "Very Strong."
• UK medical listing (IPS, grown in North Macedonia): registered at 30% THC, under 1% CBD.
• AllBud: 30–32% THC.
• JointCommerce and Vivosun: 18–24% and 18–22% — but both describe lineages that don't match the GMO × OZ Kush Bx2 cross, so treat those figures with caution.

Realistically, a well-grown cut of the real GMO × OZ Kush Bx2 lands in the mid-to-high 20s, and the GMO side gives it a heavier body than the number alone suggests. Is Black Amber a good strain? For people who like savory, gassy flower and an evening body high, yes — a 4.7/5 average on Leafly says most users agree. If you want candy-sweet fruit or a daytime buzz, it isn't the one.

THCA flower is labeled differently from dispensary flower: the lab reports THCA, which converts to THC when heated, plus a small amount of delta-9 THC. When you compare a Black Amber batch against the 21–32% range above, compare total THC on the COA, not the headline number — our guide on how to read a THCA flower COA walks through the math.

Black Amber vs Similar Strains

• vs GMO: the funky parent. GMO is more garlic-and-onion savory and slower to finish; Black Amber is sweeter, with more lime-candy and color from OZ Kush.
• vs Garlic Breath and Donny Burger: both lean harder into the GMO savory funk. Black Amber is the more balanced, approachable of the three.
• vs Gastro Pop: a fruitier Compound Genetics cross; Black Amber × Gastro Pop #5 became Gastro Funk.
• vs Super Boof: the closest match on our shelf. It shares the caryophyllene-myrcene-limonene stack, a dark-fruit-over-gas profile and a relaxed finish — but it's sweeter cherry and cream, without GMO's cheesy funk.
• vs Permanent Marker: the funk-first alternative — a loud chemical, gassy nose and an indica-leaning body. Different lineage, similar evening use.

Who Black Amber Is (and Isn't) For

Good fit: experienced smokers who like gas, funk and savory notes; evening wind-downs; people who find citrus-forward sativas too racy.

Poor fit: beginners chasing a 30% label, anyone who needs to be sharp for hours, or anyone who dislikes savory, chemical flavors. For a lighter, sweeter evening pick, Lemon Cherry Gelato is gentler on the palate.

How to Use Black Amber THCA Flower — and How Much

THCA has to be heated to do anything. Raw, it isn't intoxicating; heat converts it to THC (decarboxylation), which is why the method matters as much as the strain.

• Smoking (joint, pipe, bong): the fastest onset. Take one or two small hits, then wait 10–15 minutes before deciding on more.
• Dry-herb vaporizer: the best way around the harsh-smoke complaint. Around 350–375°F brings out the sweet, limey side; 390–410°F brings the gas, spice and heavier body.
• Pre-rolls: the no-prep option — see our THCA pre-rolls.
• Homemade edibles: decarb the flower first. Edibles take 30–120 minutes to kick in and last far longer, so start low and wait the full two hours.

How much? New or occasional users: one small puff, then wait 15–30 minutes — the body builds after the first wave. Regular users usually find two or three hits is plenty for an evening. You can always add more; you can't take it back.

Medicinal Benefits

These are uses consumers report on Leafly and similar sites, not established clinical outcomes. Individual response varies with dose, tolerance and chemotype.

• Anxiety: the most-cited reason on Leafly (about 37% of reviewers), echoed by reviews praising "no paranoia."
• Low mood: about 17%, consistent with the euphoric onset.
• Stress: about 17% — the after-work unwind most reviewers describe.
• Sleep and body tension: several reviewers use it at night to unwind and sleep; AllBud also lists chronic pain and headaches among common uses.

Side Effects and Cautions

• Dry eyes and dry mouth — the two most-reported negatives on Leafly.
• Dizziness — Leafly's third negative, usually from overdoing it.
• Harsh smoke and headache — occasional complaints, often tied to a rushed cure.
• Couch-lock and sleepiness at higher doses.

Is Black Amber good for sleep? At higher doses, often yes — but it's more calm-and-focused than knockout at a small dose. Don't drive after using it, and talk to your doctor first if you take prescription medication, are pregnant or nursing, or have a heart condition.

Is Black Amber Top Shelf? How to Judge a Good Bag

• Ask about the lineage. The real Black Amber is GMO × OZ Kush Bx2. A seller who says "unknown" or lists Purple Kush may have something else.
• A current third-party COA naming the lab, with THCA, delta-9 and total THC. Treat 32% claims without paperwork as marketing. Ours are on the lab results page.
• Funk and sweetness. Good Black Amber has diesel-chemical funk with a fruity, limey edge. Flat earth with no gas suggests old or poorly grown flower.
• Dark color and frost. Deep olive to purple buds, orange hairs and a thick trichome coat.
• A smooth smoke. Reviewers' main complaint is harshness — a proper slow cure fixes most of it. Hay or grass smell means it was rushed.

Growing Black Amber

Black Amber is still a young, mostly clone-and-feminized-seed cultivar, and neither Fullmoon nor Compound publishes detailed grow specs, so treat these numbers as guidance:

• Seeds: Compound Genetics released feminized Black Amber crosses in three-packs, plus licensed keeper phenotypes.
• Structure: medium height with stout branching and tight node spacing, per JointCommerce; topping and a trellis help carry the heavy colas.
• Flowering: about 8–9 weeks indoors, per Vivosun's guide (which lists a different lineage, so confirm with your seed source).
• Yield: Vivosun reports about 400–500 g/m² indoors and up to 600 g per plant outdoors.
• Color: night temperatures 10–15°F below daytime in late flower bring out the dark purple.
• Resin: heavy trichome coverage makes it a solid candidate for hash and rosin.

Commercial cuts have been grown by Neighborgoods (Ohio), District Cannabis (Massachusetts), Be Humble (Quebec) and PharmaCann (North Macedonia, for UK medical patients).

Is Black Amber THCA Flower Legal?

Under the 2018 Farm Bill, hemp is federally legal when it contains no more than 0.3% delta-9 THC on a dry-weight basis — see the USDA hemp program. THCA flower is sold under that rule. State laws differ and are changing, so check your state before you order. And whatever the label says, THCA flower will show up on a drug test — heated, it is THC.
