10 Clones Listed by Mass Hydroponics That Have Tested HLVD Positive

Dr. Phil is a balanced hybrid crossing dessert and OG genetics — a lineage pairing that typically produces a resin-heavy, terpene-forward cultivar with broad appeal across both flower and extract markets. The OG backbone in particular is known for dense structure and pronounced aroma, making this exactly the type of strain that gets held as a long-term mother and passed widely through commercial clone networks.

The confirmed HLVD-positive result on Dr. Phil tracked closely with how the viroid attacks OG-lineage plants: the resin expression that the OG side of the cross should deliver was measurably reduced, the dessert-forward terpene character from the genetics came in flat and underdeveloped, and plant structure showed uneven branching consistent with viroid-related growth disruption. Growers expecting the moderate but reliable yield profile this strain is marketed on reported significantly below-average output from infected material.

Carbon Candy — also listed as Carbon Candy #4 — is a Good Day Farm creation crossing Carbon Fiber with Gushers, producing a balanced hybrid that carries the candy-fruit terpene profile Gushers genetics are known for alongside the dense, resinous structure that Carbon Fiber contributes. The Gushers lineage has been one of the most widely traded families in modern cannabis, which means any clone with Gushers in its background has an elevated probability of having passed through contaminated hands at some point in its propagation history.

HLVD in this cut struck the qualities growers pay for most: the candy-fruit aromatic expression that makes it marketable came in muted and generic, the Gushers-derived bag appeal was noticeably reduced, and the 50/50 balance of structure that makes it a reliable commercial performer showed inconsistency across the canopy. Clone rooting from the infected mother was also reported as sluggish — one of the earlier indicators that a mother plant is carrying viroid load.

Han Solo Burger is a Skunk House Genetics breeders cut crossing GMO with Larry OG — a pairing that combines the deeply pungent, garlic-forward aroma of GMO with the classic California kush structure and effect profile of Larry OG. As a named breeders cut, this is the kind of clone that gets held as a prized mother and shared selectively through trusted networks. That tight circulation pattern does not prevent HLVD — it just means contamination moves more quietly and is harder to trace when it appears.

The GMO side of this cross is particularly vulnerable to the viroid's effect on terpene expression. GMO genetics are grown specifically for their extreme, distinctive pungency — that sulphurous, savory, diesel-garlic profile is the whole identity of the strain. Infected versions of Han Solo Burger saw that aroma dramatically reduced, replaced by something faint and indistinct. The body-heavy effect profile that the Larry OG side contributes also came in noticeably weaker in infected material, consistent with the potency degradation HLVD is known to cause.

Permanent Chimera #89 is a Chimera #2 and Permanent Marker cross — two genetics that carry significant market weight on their own. The strain is described as a vigorous, high-yielding plant that roughly doubles in size during flower, with thick branching capable of supporting heavy canopy loads and a glue-blueberry terpene profile. A 30%+ THC target and high yield projection makes this exactly the type of cut that commercial facilities are willing to pay a premium for and hold as a permanent mother.

That ambitious profile makes the HLVD-positive result particularly damaging. The doubling stretch in flower that this cross is known for was stunted in infected plants — vertical growth came in noticeably reduced, and the thick branching structure that supports its high-yield potential showed weakness and inconsistency. The glue-blueberry terpene expression that sets it apart from generic high-THC hybrids was suppressed, and potency results on infected material came in well below the 30%+ benchmark the strain is marketed on. For growers who acquired this cut specifically for its yield and THC profile, HLVD effectively eliminates both.

Octane Mintz crosses Sunset Octane with Wedding Cake, a combination that brings together high-octane fuel aromatics and the creamy vanilla-mint dessert notes that Wedding Cake genetics contribute. The result is marketed as a bold, complex terpene experience — sweet mint layered with creamy vanilla and fuel undertones. Complexity like that is exactly what HLVD destroys most efficiently. Infected plants don't just lose volume — they lose the layered character that distinguishes premium genetics from commodity cannabis.

The confirmed positive version of Octane Mintz lost most of what makes it worth sourcing. The mint-vanilla complexity that defines the strain's aromatic identity was almost entirely absent at harvest, replaced by a thin, generic sweetness that conveyed none of the strain's signature character. Sunset Octane's fuel-forward punch was similarly diminished. Trichome density was reduced, and growers noted that the visual impact of the flowers — the frost-covered, dense structure Wedding Cake crosses typically deliver — was noticeably below standard for the genetics.

Permanent Cherries is a SeedJunky Genetics creation — a three-way cross of Lemon Cherry, Kush Mints Bx1, and Permanent Marker. SeedJunky releases carry significant market weight, and this particular combination stacks lemon-cherry fruit aromatics, the cool minty finish Kush Mints is known for, and the resin production that Permanent Marker brings to any cross. The pedigree makes it a highly desirable acquisition, and high-desirability genetics are exactly what move fastest through clone networks — increasing contamination exposure at every transfer.

Infected versions of Permanent Cherries lost the layered aromatic complexity that justifies SeedJunky's reputation. The lemon-cherry top notes that should lead the nose came in faint and flat, the cool mint finish was nearly undetectable, and the Permanent Marker-derived resin production that should make this a standout in any room was noticeably suppressed. Clone quality from the infected mother was inconsistent — rooting rates were lower than expected for a healthy SeedJunky cut, and early vegetative growth showed the kind of slow, uneven development that often precedes more obvious viroid symptoms at flower.

The Blue Dream Santa Cruz Cut is one of the most historically significant clones in American cannabis. It has been in continuous circulation for longer than most modern hybrid genetics have existed, passing through generations of growers across California and beyond. A strain with that kind of legacy and that length of circulation history is one that has had decades of exposure to every contamination vector imaginable — which makes its confirmed HLVD-positive status unsurprising even if it is still significant.

What matters about this result is the implication for growers who hold what they believe to be the authentic Santa Cruz Cut. Many holders of this clone received it several transfers removed from the original source, often through informal networks where the provenance is assumed rather than verified. The HLVD-positive version displayed suppressed blueberry and sweet haze aromatics — the exact sensory markers that distinguish an authentic Blue Dream from a generic copy. The energizing, cerebral effect profile the strain is known for was also reported as diminished in infected plants, with a heavier, sluggish character replacing the uplifting quality that defines the strain's reputation.

AJ's Cut of Sour Diesel is not just a popular strain — it is one of the most historically significant and actively sought-after clone-only cuts in the entire history of American cannabis. Its lineage traces directly back to the original Chemdawg cut held by AJ, one of the most respected figures in East Coast cannabis genetics history. The cut has been in near-continuous circulation since the early 1990s, making its transfer history longer and more complex than virtually any other clone on this list.

Decades of transfers, each representing a potential contamination event, mean that HLVD exposure risk for this cut is exceptionally high — and the confirmed positive result reflects that reality. The pungent, fast-hitting diesel-fuel aroma that defines AJ's Sour Diesel and distinguishes it from other Sour D phenotypes was severely suppressed in the infected version. The energizing, almost cerebral sativa effect that gives this cut its legendary status came in blunted and unremarkable. For a strain whose value is almost entirely tied to authenticity and terpene character, HLVD is particularly destructive — it turns one of cannabis's most distinctive cuts into something indistinguishable from any generic sativa.

NYC Sour Diesel carries the East Coast Sour Diesel lineage with Skunk in its background, producing a sativa-dominant hybrid known for euphoric, uplifting effects and the classic diesel aroma profile that defines the New York cannabis tradition. Like AJ's Cut, NYC Sour Diesel has been in circulation long enough that many current holders received it through informal chains where testing was never part of the handoff.

The infected version of NYC Sour Diesel presented a familiar pattern for diesel-lineage cuts carrying HLVD: the sharp, pungent fuel aroma that is the entire point of sourcing a Sour Diesel cut came in weak and diffuse, losing the edge and intensity that makes the strain recognizable. The euphoric, clear-headed effect profile was also compromised — users of infected material described a heavier, less functional experience compared to what healthy NYC Sour Diesel should deliver. High yield potential listed for this strain was also not realized in infected runs, with canopy development uneven and overall biomass per plant below expected range.

Galactic Warheads is a collaboration between Craft Farmer and Dank Mob — a Runtz × Gelato 41 cross marketed specifically as a clone-only cultivar, known for a sweet-sour candy terpene profile with tropical fruit and fuel undertones. Clone-only status typically implies prestige and selectivity, but it also means the genetics exist only in cutting propagation — there is no seed population to fall back on, and every copy is a direct genetic descendant of whatever mother stock was originally distributed. If that source material carried HLVD, every subsequent cut does too.

The Runtz × Gelato 41 combination stacks two of the most terpene-forward genetics in modern cannabis. Runtz brings intense candy-fruit aromatics; Gelato 41 contributes creamy sweetness and dense, frosty structure. HLVD attacked both qualities in the confirmed positive cut. The sweet-sour tropical candy profile that defines Galactic Warheads was largely absent — replaced by a pale, underdeveloped sweetness that could belong to any generic hybrid. The Gelato-derived frost and density were reduced, undermining both the visual appeal and extract potential of the cut. For a strain that commands a premium specifically because of its terpene character and clone-only rarity, HLVD renders the premium unjustifiable.
