The Clone Foundry Catalog: 10 Strains That Came Back HLVd Positive

Peach Pistols is a BeLeaf Cannabis sativa-dominant hybrid built around an unusual genetic pairing — Love Seed 2.287 crossed with Odo #1. BeLeaf releases tend to carry distinctive terpene identities, and Peach Pistols is no exception: the strain is known for a stone fruit-forward aromatic profile with a brightness that leans sativa in character. That terpene expressiveness is exactly the quality HLVd quietly dismantles before a grower can trace what went wrong.

In infected plants, the peachy, fruited top notes that define this strain's identity faded significantly at flower. What remained was a generically sweet, indistinct aroma that could belong to any number of hybrid cultivars — nothing that signals the BeLeaf breeding program or justifies the premium attached to a named breeder cut. Sativa-leaning growth structure was also disrupted, with infected plants showing reduced lateral branching and slower canopy development than a healthy expression of this cut should produce.

Cobra Chi crosses Margwa #1 with Chimera #3, two BeLeaf genetics that bring an exotic, complex aromatic character to their offspring. The Chimera lineage in particular is known for pushing terpene profiles toward the unusual — it tends to produce cultivars that smell and taste unlike anything in the standard commercial catalog. That distinctiveness is precisely why HLVd infection is so damaging here: the strain's entire value rests on sensory qualities that the viroid suppresses.

The infected version of Cobra Chi lost the complexity that makes it a standout. Instead of the layered, exotic aromatic character the Margwa and Chimera genetics should deliver, growers reported a flat, one-dimensional smell profile at harvest. Structure-wise, the balanced hybrid vigour that 50/50 crosses typically display was replaced by uneven growth, with some branches failing to develop at the same rate as others — a common sign of viroid load disrupting the plant's internal resource allocation.

The Santa Cruz Cut of Blue Dream is one of the most replicated clones in American cannabis history — and that history is precisely the problem. A cut that has changed hands this many times, across this many years, has been exposed to every possible contamination vector. Each unverified transfer is another opportunity for HLVd to enter the line. By the time it reaches a new grower, there may be no reliable record of when or where the infection occurred.

This confirmed positive is significant beyond just the single cut. Blue Dream Santa Cruz is the kind of strain that many growers hold with deep trust, often passed along from someone they consider a credible source. That trust does not screen for HLVd. Infected plants in this case showed the suppressed blueberry sweetness and dulled haze character that define the authentic cut's identity — two of the most reliable sensory markers for distinguishing a real Santa Cruz expression from an inferior copy were gone, replaced by a generic sweetness and reduced aromatic presence.

AJ's Sour Diesel needs little introduction. As one of the founding cuts of East Coast cannabis culture, it carries a reputation that most modern strains will never approach. The problem with legendary status in the clone world is that it creates enormous demand — and enormous demand means the cut moves through many hands, many of which never tested it. At this point in the strain's long history, confirmed HLVd positives in circulation should not come as a surprise. They are the predictable consequence of decades without systematic testing.

What HLVd takes from AJ's Sour Diesel is its identity. The fuel-soaked, sharp diesel punch that makes this cut immediately recognizable — the quality that has kept it in demand across three decades — was severely diminished in the infected version. The energizing, mentally clarifying sativa effect profile that distinguishes AJ's from ordinary Sour D phenotypes was similarly compromised. When an infected cut of AJ's no longer smells or effects like AJ's, the entire case for running it collapses.

Florida OG — known in certain circles as Crippy or Ocean-Grown — is a heirloom OG Kush phenotype with deep roots in Florida's cannabis community. As a clone-only heirloom, it has no seed population to draw from. Every version in existence descends from cutting propagation, meaning its entire genetic preservation depends on the health of the mother plants holding it. If those mothers are infected, there is no clean backup to return to without tissue culture intervention.

The confirmed HLVd-positive result on Florida OG represents a real threat to the preservation of this cut. The classic OG Kush qualities that define it — the fuel-lemon pine aroma, the heavy indica structure, the resin load that makes it a standout in any OG collection — were all measurably diminished in infected material. Clones from the infected mother also showed poor rooting rates and sluggish early growth, suggesting the viroid load had been building across multiple cutting cycles before the test was conducted.

Chem D is one of the original Chemdawg phenotypes — a sister selection alongside Chem 91, Chem #4, and Chem Sis, all descending from the same Dogbud seed stock that gave rise to an entire category of cannabis. These are among the most historically significant cuts in the industry, preserved by collectors and passed through connoisseur networks for over thirty years. Smash Hits holds this as an heirloom preserved cut, which indicates serious curatorial intent — but curation without regular PCR screening cannot catch HLVd.

In an infected Chem D plant, the signature qualities of the Chemdawg lineage are the first casualties. The distinctive pungent, chemical-fuel aroma that sets Chem D apart from every other indica-dominant hybrid on the market was notably suppressed. The heavy, resinous bud structure that makes Chem D a washer staple showed reduced density and lighter trichome coverage. For growers who specifically sought out this cut for its heritage and its extraction potential, infected material delivers neither the genetics' identity nor its commercial utility.

Dulce de Uva is a Bloom Seed Co cultivar crossing Grape Pie with OG Kush — a combination that stacks rich candy-grape sweetness from the Grape Pie side against the structural density and fuel undertones of OG Kush. Bloom's heritage breeder cuts are released specifically for their terpene distinctiveness, and the grape-candy profile of Dulce de Uva is what makes it worth seeking out. HLVd's documented impact on terpene output makes this an especially costly infection to carry in a strain sold primarily on flavor.

Growers running the infected version of Dulce de Uva reported that the rich, candy-grape character the strain is named for — "dulce de uva" translates simply as grape candy — came through thin and washed-out at harvest. The OG Kush-derived density and fuel complexity that should balance the sweetness were also reduced. What remained was a mildly sweet, unremarkable indica profile that conveyed nothing distinctive about the Bloom Seed Co breeding program or the Grape Pie lineage.

Chem #4 — Chemdawg #4 — is one of the "Final Four" phenotypes selected from the original Dogbud seed lot that produced the entire Chemdawg legacy. Alongside Chem D appearing earlier in this list, its confirmed positive result means two of the foundational Chemdawg phenotypes in The Clone Foundry's catalog tested infected. These are cuts that serious collectors have fought to preserve for decades. Finding HLVd in them is a sobering reminder that preservation without testing is not preservation at all.

Chem #4 carries a slightly different aromatic character than Chem D — leaning more toward a sour, acidic diesel rather than the deep chemical-fuel of its sibling. That distinctive sour edge was among the first things lost in infected plants. The indica-leaning structure that makes Chem #4 productive in a controlled environment also suffered, with infected plants showing thinner stems and a canopy that struggled to fill evenly. For anyone running this as part of a Chemdawg preservation project, an infected mother plant is not preserving anything worth passing forward.

Josh D OG is a serious OG legacy cut — a four-way cross of Triangle Kush, SFV OG, Hell's Angels OG, and The White, held through Karma Genetics. Each parent in that combination carries significant weight in the OG Kush world, and together they produce a cultivar with deep indica-dominant structure, a pronounced lemon-fuel kush aroma, and the kind of resin production that has made Josh D's name synonymous with premium OG genetics for years.

The HLVd-positive result on this cut is notable because Josh D OG is the kind of genetics that commercial facilities and serious home growers seek out specifically for consistency and quality. Infected material delivered neither. The lemon-fuel kush aroma that is the calling card of the OG Kush family was weakened and muddied, the four-parent resin complexity the strain should express was reduced to something more ordinary, and yield came in below what the genetics should produce under the same conditions. All four of the strain's legendary parent lines were effectively undermined by a single viroid load in the mother plant.

Astronaut Status #24 is a Clear Water Genetics selection from a Zero Gravity and Mai Tai #4 cross — a balanced hybrid that sits at the intersection of tropical fruit aromatics and the creamy, exotic character that Mai Tai genetics carry. As a numbered phenotype from a recognized breeder, it represents the kind of intentional, curated selection that commands collector attention. The "#24" designation signals a specific, chosen expression — exactly the type of plant that gets held as a permanent mother and treated as irreplaceable.

That irreplaceable quality is what makes an HLVd-positive result especially costly. The tropical and exotic aromatic profile that justifies selecting a specific phenotype number over the others in a population was significantly muted in the infected plant. The balanced structure that 50/50 hybrids can deliver — vigorous but manageable, productive on both sides of the spectrum — was uneven, with growth inconsistency between branches that made canopy training difficult. Growers who acquired this cut specifically for its numbered selection status received, in practice, a diminished version of what that selection was supposed to represent.
