What is HLVd (Hop Latent Viroid)?
Hop Latent Viroid (HLVd) is a microscopic pathogen that infects cannabis plants, often without visible symptoms until harvest. Infected plants can show 30–50% reduction in THC content, smaller buds, reduced terpene production, and stunted growth. HLVd spreads through contaminated tools, infected cuttings, and even water runoff.
Our Testing Protocol
Mother Plant Testing
Every mother plant in our library is PCR tested regularly to ensure viroid-free status before any cuttings are taken.
PCR Testing
We use RT-qPCR (quantitative polymerase chain reaction), the gold standard for HLVd detection, with sensitivity down to single viroid copies.
Clean Room Propagation
All cuttings are rooted in our dedicated propagation rooms with strict sanitation protocols, tool sterilization, and isolated environments.
New genetics never go straight into our mother room. Every incoming cut is quarantined and PCR-tested first — and roughly 28% of incoming genetics test positive for HLVd before they ever reach our library. Those are cleaned or rejected, never propagated. We screen every mother for both Hop Latent Viroid and Fusarium, running several hundred tests a year to keep the library clean.
Signs of HLVd Infection
- ✕Reduced trichome production and lower THC content (30-50% reduction)
- ✕Smaller, less dense buds ("dudding")
- ✕Stunted growth and reduced vigor
- ✕Brittle stems and branches
- ✕Looser bud structure
- ✕Reduced terpene production and weaker aroma
Why Buy HLVD-Tested Clones?
Starting with clean genetics is the single most impactful thing you can do to protect your harvest. A single infected clone can spread HLVd through your entire facility via contaminated tools and water. By the time symptoms appear at harvest, the viroid has already spread.
At Prime Cuts Nursery, we invest heavily in testing and prevention so you don't have to worry. Every clone that leaves our facility has been verified clean.
Clone Buyer's Checklist: 5 Questions to Ask Any Nursery
Before you buy clones from anyone, ask these. A nursery that tests properly will answer them without hesitation.
- Do you PCR-test every mother plant for HLVd — and how often?
- Do you quarantine and test incoming genetics before propagating them?
- Do you also screen for Fusarium and other pathogens?
- Can I see a recent COA or test result for the genetics I'm buying?
- Where are cuttings rooted, and what are your sanitation protocols?
