GreenThumbDepot helps commercial cultivators eliminate HLVd, protect elite genetics, and build production-grade tissue culture labs — from first consultation to full operation.
Request commercial pricing, ask about rebates, or just sanity check your light setup.

Hop Latent Viroid has been called "the COVID of cannabis." The numbers back it up — and traditional cloning won't save you.
A 2021 survey found 90% of California cannabis facilities had “dudding,” causing up to 35% cannabinoid loss in healthy-looking plants.
~90% of CA facilities infectedHLVd can cut yields by 70% and cannabinoids by 35% before symptoms appear—often infecting the entire clone stock.
Up to 70% yield lossIf a mother plant has HLVd, every clone inherits it—and without a cure, traditional propagation only spreads the problem.
No chemical cure exists
Meristem tip culture, using tissue as small as 0.4 mm, is the only proven way to produce HLVd-free plants.
Paired with proper screening, it not only stops HLVd but ensures a clean genetic foundation.
This isn't optional anymore. This is how serious operators are protecting their businesses.
From HLVd elimination to 10x propagation output, tissue culture rewrites what's possible for commercial cultivation.
Meristem tip culture produces viroid-free plants, stopping contamination.
Only proven solutionEvery plant is identical—no drift, no mutations, consistent harvests.
Tissue culture replaces mother rooms, yielding 36× more plants.
36x propagation productivityTC plants yield ~75% more per square foot, consistently.
~75% more yield/sq ftLong-term preservation safely stores cultivars, preventing loss from disease.
Rapidly multiply plants without expanding rooms, labor, or contamination risk.
Most growers attempting DIY tissue culture end up with contamination and failed cultures, since the process requires true expertise.
That's where we come in.
Meet Elliott Gorfain — 27 Years in Controlled Environment Agriculture. Elliott Gorfain, a molecular biologist, horticulturist, and patented inventor, brings 27 years of hands-on indoor cultivation experience to our commercial consulting practice, offering real-world expertise in growing, retail, product development, and operations—never scripted advice.
Most growers who set up a TC lab on their own hit the same wall — contamination, failed cultures, and wasted budget. We close that gap with eight concierge services.
We evaluate your space, infrastructure, and operational goals to determine exactly what your TC lab needs. No cookie-cutter solutions — every assessment is tailored to your facility.
A layout built for your specific facility, optimized for workflow efficiency and future scalability. We design it right the first time so you're not retrofitting six months in.
No guessing, no overspending. We spec the right tools for your lab and supply them through GreenThumbDepot — laminar flow hoods, autoclaves, culture vessels, media prep stations, and all consumables.
We ensure every piece of equipment is installed, calibrated, and functioning properly before you run your first culture. Your lab goes live ready to produce — not ready to troubleshoot.
Your team learns to operate the lab with confidence — not from videos, from real experts working alongside you. We train your people until they can run the operation independently.
Standardized operating procedures tailored to your lab, your genetics, and your workflow. Every run is consistent, every process documented, every team member on the same page.
Data-driven management tools to monitor cultures, track success rates, and optimize performance over time. You'll know exactly what's working and what needs adjustment.
We don't disappear after buildout. Our team is with you every step of the way — from first culture to full-scale production and beyond.
A production tissue culture lab doesn't have to be a million-dollar facility. Starting budgets for a functional lab range from approximately $50K to $250K, with costs generally split evenly between buildout and equipment. High-end commercial operations can scale to $1M–$5M+, but the right starting point depends entirely on your operation.
Where glassware and tools are cleaned and autoclaved. The foundation of contamination control — everything that enters your clean room passes through here first.
Where growth media, hormones, and gelling agents are mixed. Precision here drives consistency across every culture plate and vessel in your lab.
The heart of the operation, where cultures are initiated under HEPA-filtered laminar flow hoods. Every transfer, every explant, every sub-culture happens here in a controlled aseptic environment.
Where developing plantlets are maintained under controlled light and temperature. Environmental consistency here directly determines success rates and uniformity of output.
From your first call to your lab producing clean plants — here's exactly what to expect.
Tell us about your operation — your genetics, your goals, your challenges. Takes 60 seconds. No calendar friction, no back-and-forth scheduling.
Elliott evaluates your space and infrastructure, then builds a custom lab design optimized for your workflow and budget. No templates — every plan is built for your facility.
We supply the right equipment through GreenThumbDepot, oversee installation, and commission every piece before your first culture run. Your lab goes live ready to produce.
Hands-on training for your team, customized SOPs for your genetics and workflow, and continuous support as you scale from first culture to full production.
