Hop Latent Viroid continues to move silently through the cannabis clone market. Six strains currently listed for sale on Marijuana Clones Online have been confirmed as infected — and because many infected plants show no early symptoms, contamination can spread for months before a grower realizes anything is wrong.
The six strains below were submitted for PCR testing through 3R Biotech, one of the cannabis industry's established plant pathogen testing providers. Each returned a confirmed positive result for HLVd. Contaminated versions of these strains are actively listed for sale and have likely moved through multiple hands.
Apples & Bananas
HLVD Positive — 3R Biotech PCRApples & Bananas became one of the most replicated cuts in recent years — first for its distinctive fruity-fuel terpene profile, then for its commercial appeal in extract and flower markets. That popularity made it one of the most passed-around clones in the industry, and heavy circulation history is exactly the kind of environment where HLVd spreads without anyone catching it.
The confirmed HLVd-positive version of this cut exhibited classic viroid symptoms in later growth stages: noticeably reduced trichome production, flowers that lacked the density and resin expression the strain is known for, and terpene intensity that fell significantly short of what healthy versions produce. Early growth stages showed little warning. Clones rooted, plants established — and then performance quietly collapsed at canopy and flower.
Lemon Cherry Gelato
HLVD Positive — 3R Biotech PCRLemon Cherry Gelato exploded in popularity as one of the most hyped strains in the modern market, appearing in commercial facilities, private clone circles, and large-scale production runs across multiple states. With that level of exposure comes risk — and this cut's confirmed HLVd-positive result reflects exactly how fast a viroid can embed itself into a popular clone line.
What makes this result particularly concerning for growers is that Lemon Cherry Gelato is known specifically for its terpene expression — the loud citrus and sweet-dessert profile is the whole point of the strain. HLVd directly impacts terpene production. Infected plants reportedly displayed muted, flat aromatics, disappointing jar presence, and visibly inferior bag appeal compared to clean versions. Yields were reduced, and canopy development appeared uneven across infected runs.
Dante's Inferno
HLVD Positive — 3R Biotech PCRDante's Inferno built a strong reputation in craft and connoisseur markets, traded among collectors and held as a keeper cut across multiple regions. Strains that circulate this way — passing between breeders, preserved as long-term mothers, shared through trusted networks — often accumulate contamination risk over time without any single transfer being the obvious origin point.
The HLVd-positive result on this cut came alongside reports of progressively deteriorating mother plant performance. Long-term mothers of Dante's Inferno that had been producing healthy-looking clones began showing weak lateral branching, thinner stems, and reduced uptake. Clones taken late from infected mothers demonstrated rooting delays and early growth inconsistency — textbook signs of viroid load building up in a long-running mother stock.
Yellow Zushi
HLVD Positive — 3R Biotech PCRYellow Zushi is a strain that carried significant hype through clone-only circles, prized for its unique terpene expression and visual bag appeal at harvest. Cuts like this often get passed down through informal networks where testing is rarely prioritized — growers trust the source, the source trusted theirs, and somewhere in that chain contaminated stock entered circulation.
Growers working with this HLVd-positive cut reported the bud structure suffered most visibly. Where Yellow Zushi is known for its appearance, infected plants produced airy, underdeveloped flowers with noticeably reduced calyx stacking. The visual signature of the strain — the quality that makes it appealing in the first place — was significantly degraded. Terpene output also took a hit, with growers describing the aroma as a pale version of what clean Yellow Zushi should smell like.
Cap Junky
HLVD Positive — 3R Biotech PCRCap Junky rose quickly to become one of the most sought-after cuts in the modern cannabis market, crossing into commercial facilities and private collections simultaneously. The faster a strain moves through commercial nurseries and production environments, the faster any contamination present in the supply chain spreads — and with Cap Junky's demand level, that risk was always elevated.
The infected version of Cap Junky tested positive at a stage when the plants were still visually asymptomatic, which is precisely why PCR testing matters. By the time the grow cycle completed, significant trichome reduction was evident and cannabinoid potency tested lower than expected benchmarks for the strain. This is one of the clearest examples in this list of how HLVd can move through a facility invisibly — with no obvious red flags during propagation, only underperformance at harvest explaining the losses.
Cadillac Rainbow
HLVD Positive — 3R Biotech PCRCadillac Rainbow earned its following through standout visual appeal and a complex terpene profile that resonated with both consumers and extract producers. It made its way through commercial nurseries and high-volume production operations, where the combination of scale and limited testing protocols creates the ideal conditions for undetected HLVd spread.
The confirmed positive result on this cut came with documented reports of stunted plant vigor across multiple grow cycles. Cadillac Rainbow plants working from an infected mother showed reduced node spacing, slower overall development, and canopy inconsistency that made even light distribution difficult to manage. Extract yield from infected material was reported as significantly below what healthy versions of the strain produce — a critical issue for any operation running it specifically for wash or extraction output.
