HLVd Remediation and Clean Gen-0
Get HLVd out of your genetics. For good.
HLVd, hop latent viroid, also written HpLVd, hides in healthy-looking plants and quietly cuts your yield and potency. Meristem culture is the only proven way to remove it. We do the cleanup in your facility, on your cultivars, and hand your team clean Gen-0 mother stock verified by qPCR.
Why standard cleanup does not work
You cannot spray it out, and you cannot test it out.
Testing tells you which plants are infected. It does not clean them. Tool sterilization and isolation slow the spread, but by the time you see the dudding, the viroid is already systemic inside your elite cultivars. The only method proven to remove it is meristem culture: isolating the tiny meristematic dome at the growing tip, ahead of where the viroid has reached, and regenerating a clean plant from it.
How we do it
Meristem culture, verified by qPCR.
Meristem isolation
We dissect the meristem under magnification, below the point the viroid reaches, and initiate it into tissue culture.
qPCR verification
Every candidate line is tested by qPCR, so clean means confirmed clean, not assumed clean.
Clean Gen-0 mothers
We regenerate your cultivar from the clean tip into vigorous Gen-0 mother stock, free of HLVd and reset from the epigenetic decline that builds up in an old mother room.
In your facility, on your team
We run the cleanup in your lab and train your technicians to do it themselves, so you hold the line on your own library instead of calling a vendor every time.
What you get back
Your elite cultivars, saved instead of culled.
- Clean Gen-0 mother stock, verified HLVd-free by qPCR.
- Restored vigor: plants that grow and yield like the cultivar did before the viroid took hold.
- A team that can keep new incoming genetics clean, with the SOPs and training to do it.
- A clean-stock program you own, not a dependency on an outside lab.
We built District Cannabis a full in-house lab in about six months, and we have preserved 250+ cultivars coast to coast.

HLVd questions
HLVd and HpLVd, answered.
Is HLVd the same as HpLVd?
Yes. HLVd and HpLVd are two abbreviations for the same pathogen, hop latent viroid. We write HLVd. Some testing labs and growers write HpLVd. It is the same viroid, the same yield loss, and the same cleanup through meristem culture.
Can tissue culture really remove HLVd?
Yes. Meristem culture is the only method proven to eliminate HLVd from an infected cultivar. You isolate the clean meristem, regenerate the plant from it, and verify the result by qPCR.
Do you offer HLVd remediation as a service?
Yes. We remediate HLVd, also written HpLVd, in your facility and on your cultivars, and we train your team to keep new genetics clean, so the clean-stock program is something you own and run.
How long does HLVd cleanup take?
It runs on the state of your library. Meristem isolation, regeneration, and qPCR verification take months, not weeks, and we scope the timeline with you on the consultation.
