Key takeaways
- On consignment, the owner keeps the equipment until a grower commits to it, and every listing in the marketplace shows its condition and the city and state where it sits.
- Ask for the nameplate, run hours, service history and a power-on video before you commit to any used unit.
- Judge a used LED fixture by its hours against the DLC benchmark of 36,000 hours to Q90, and confirm whether any warranty transfers.
- Clean dehumidifier coils gently, fit a MERV-11 or better filter, and have an HVAC technician check refrigerant equipment before it runs in your room.
- If you are downsizing a room, consignment usually takes longer than an auction and tends to return more, so prepare photos, manuals and service logs up front.
Commercial cultivation moves in cycles. A facility expands, re-tools for a new crop, consolidates two rooms into one or closes a building, and the equipment that ran those rooms does not stop being useful when the plan changes. Used grow equipment offered on consignment puts that gear, from LED fixtures and HVAC to flood tables, trimmers and post-harvest lines, in front of growers who need it now.
This guide explains what used, pre-owned and consignment actually mean, how to judge a unit before you commit to it, and what is currently listed in the GrowersHouse Consignment Equipment Marketplace. It covers hydroponics, indoor cultivation, greenhouse and CEA equipment, along with the extraction, lab and packaging machines that sit downstream of the harvest. If you run a room that is shrinking, the last sections cover selling and consigning your own equipment.
Used vs new: what consignment means and when pre-owned pays off
The words get used loosely, and the differences matter when you are pricing a fixture or a dehumidifier against its new equivalent.
Used, pre-owned, surplus and consignment
Used and pre-owned mean the same thing: the equipment has been installed or operated before. Surplus equipment is new stock left over from a build that changed scope, which is why some marketplace listings carry a New or "Brand New – Never Installed" condition. Consignment describes how the equipment reaches you rather than what state it is in. The owner keeps title, a third party markets the unit, and the owner is paid once it finds a buyer, with the consignment fee coming out of those proceeds.
Refurbished is a separate category. A refurbished unit has been repaired and tested, often by the manufacturer, before it goes back out. A consignment listing is offered as described by its owner, so the condition label and the photos carry the weight. In this marketplace, conditions run from New and Used-Like New through Used, and some listings name the wear outright, such as "Used – Cleaning Recommended" on a lot of flood tables or "Used – Access Door Damaged" on a dry trimmer. That candour is useful. It tells you exactly what to ask about.
Where used equipment makes sense
Lead time is the first reason growers look at pre-owned cultivation equipment. A dehumidifier or a bucking machine that is already crated on a pallet can be in your room in days, while a new commercial unit may carry a lead time that runs past the start of your next cycle. Price is the second, and the gap against the same model new is worth checking listing by listing. The third reason gets overlooked: matching what you already run. If your flower rooms are built around one dehumidifier model or one fixture family, a used unit of the same model shares your filters, spare drivers and controller settings. Indoor rooms, greenhouses and larger CEA facilities also run on much of the same equipment, so a dehumidifier, LED fixture or fan from one kind of operation can serve another.
Where new is the better call
Warranty is the honest counterweight. The DesignLights Consortium requires horticultural luminaires on its qualified list to carry a warranty of at least five years, but a used fixture's coverage may not transfer to a second owner, so ask before you count on it. Efficiency moves too. The current DLC horticultural requirements, accepted from April 18, 2025, set a minimum photon efficacy of 2.5 µmol/J, and an older fixture may fall short of that benchmark. Equipment with no service history and many moving parts, such as a trimmer with worn reels, can cost more in repairs than it saved. When budget is the reason you are looking at used gear, it is worth comparing against financing new equipment before you decide.
How to check used grow equipment before you commit
Every listing in the marketplace has an inquiry path for specifications, photos and shipping details. Use it, and ask for the same eight things on every unit.
Eight checks for any used unit
- Ask for a photo of the nameplate showing make, model and serial number, then compare it with the manufacturer's spec sheet for that exact model.
- Ask for run hours and service records: hours-on for lights, filter changes and coil cleaning for dehumidifiers, reel and blade replacements for trimmers.
- Match the electrical supply. Voltage, phase and amperage on the nameplate have to agree with your panel, and gas-fired heaters need a gas line where they will hang.
- Request current photos and a short power-on video, so you see the unit running rather than a catalogue image.
- Confirm that consumables and spare parts are still available for the model, including filters, drivers, blades and seals.
- Plan the freight before you commit: crated weight, pallet count, and whether the destination has a forklift or needs a liftgate.
- For anything that touched plant material or chemicals, such as trimmers, extraction systems and lab instruments, ask how it was cleaned or decontaminated.
- Price the unit against its new equivalent plus installation, and decide what margin justifies giving up a full warranty.
Freight deserves more weight than most growers give it. A 5-ton air conditioner or a run of 4' x 8' flood tables can cost real money to move across the country, which is why each listing names the city and state where the equipment sits. A nearby unit at a slightly higher price often lands cheaper than a distant one. The marketplace team assists with logistics on distant pieces once you commit.
Treat the condition label as the starting point of the conversation, not the end of it. "Used-Like New" on a dehumidifier that ran one season in a clean room is a very different unit from one that ran three years beside a nutrient reservoir, and only the history tells you which you are looking at. If the owner cannot answer the basic questions above, that is an answer too.
Used LED grow lights and hydroponic systems
Lighting and hydroponic systems are where most growers start, because both are expensive new and both are easy to inspect.
LEDs and lighting
LED diodes dim gradually rather than burning out like a bulb, so the question is how much output is left. The DesignLights Consortium measures this with Q90, the number of hours before a fixture's photon output falls to 90% of its starting value, and requires at least 36,000 hours to Q90 for its qualified list, with drivers rated for at least 50,000 hours. On a 12-hour flower schedule a fixture runs 4,380 hours a year, so 36,000 hours is a little over eight years of flowering. A fixture with two years of run time on it still has most of that ahead of it, provided its model was rated to that benchmark in the first place. The SPYDR 2x47, for instance, carries a 5-year limited warranty and an L90 rating beyond 50,000 hours, and its input voltage options include 120-277 V and 347-400 V, which is exactly the detail to check against your panel.
The lighting listings below include top-light LEDs, intra-canopy LED bars and double-ended HPS, which some growers still prefer for its spectrum and radiant heat in cooler rooms. Before you commit, inspect the lenses and diode boards for discoloration, check that the dimming leads and connectors are intact, and run each fixture for at least an hour. To compare any used fixture with current models and efficiencies, the LED grow lights collection lists the new range.

|---|---|---|
| Eco Grow 1000W Grow Lights | New | Rancho Cucamonga, CA |
| Efinity S840 840W LED Grow Light | New | Rancho Cucamonga, CA |

| Illuminar 240V DEHPS Grow Light | New | Corona, CA |
| Illuminar iLogic 1030 Full Spectrum Plus LED Grow Light | New | Corona, CA |
| Think Grow Horticulture LED Light | New | Tupelo, MS |
Flood tables, reservoirs and fertigation
Ebb-and-flow hydroponics is the simplest system to source pre-owned. A flood table is a molded plastic tray that fills from a reservoir and drains back, so roots get water and air in turns. There is nothing electrical in the tray itself, which means the inspection comes down to cracks, warping, and the condition of the fill and drain fittings. Several flood table and grow tray listings are surplus in New condition, and one lot of Botanicare 4' x 8' tables is marked for cleaning, which a pressure wash and a sanitizer rinse usually handle. Reservoirs, a TrolMaster Hydro-X environmental control system and a commercial fertigation skid round out the group. For fittings, drains and new tables to complete a system, see the ebb and flow systems collection.
Used HVAC, dehumidifiers and climate equipment
A sealed room gains humidity fast, because plants release most of the water they take up back into the air. That makes dehumidifiers and air conditioning the equipment a room cannot run without, and the hardest to replace on short notice.
The listings include Quest and Anden dehumidifiers, an Excel Evolution air conditioner, a Goodman 5-ton split system, Modine natural gas unit heaters rated at 164,000 and 207,500 BTU, PHAT inline fans and Patterson industrial fans. Several heaters date from 2022 to 2025, which is recent equipment by HVAC standards. Air conditioners and split systems carry refrigerant, so have a licensed HVAC technician check the charge and the refrigerant type on the nameplate before a used system goes into service. For new units, controllers and ducting to pair with used equipment, see the HVAC collection.
Quest's own maintenance guidance is a good standard for any used dehumidifier. Clean the coils only when dirt or debris has built up, and do it gently: unplug the unit, vacuum loose debris, blow out dust with compressed air, and rinse with warm water if needed. Skip household cleaners, which can corrode the coils, and use rubbing alcohol if you want to disinfect. Dry the unit with fans afterwards to prevent corrosion, and fit a MERV-11 or higher filter. Our guide to Quest and Anden filter sizes and replacement timing lists the correct filter for each model, which matters on older Quest units because two generations share model numbers and use different filter sizes.
Post-harvest equipment: trimmers, buckers, sorters and drying
A hydroponic room can turn crops quickly, and harvest labor is often where the schedule backs up. Post-harvest equipment is where a used machine can pay for itself in a single harvest.
The machines divide by job. Buckers strip flowers from the stems, trimmers remove excess leaf, and sorters grade flowers by size before packing. The marketplace lists a Twister T4 trimmer and a B4 bucker, a CenturionPro HP3 bucker and CenturionPro dry trimming unit, Triminator dry trimmers, EZTRIM and GreenBroz sorters, and an EZ Trim Satellite in New condition. Drying and curing are covered by vertical drying racks, a large Auto Cure automated curing unit and a pallet lot of Curetube containers, and two decontamination systems, an X-ray unit and a sterilization vacuum pump, finish the group.
On trimmers and buckers, the wear parts tell the story. Ask about the reel or blade assembly, the tumbler mesh, the motor and any belts, and whether replacement parts for that model are still made. A trimmer that has been cleaned between every harvest looks different in photos from one that has not, and resin buildup on the tumbler is easy to spot. Compare used machines with new models in the trimmers and buckers collection, and see drying and post-harvest preservation for racks, curing containers and humidity control to finish the room.

Joint rollers, extraction, lab and packaging equipment
Downstream of the harvest, equipment turns flower into pre-rolls, concentrates and packaged goods. These machines are specialized, expensive new, and among the most frequently resold when a facility changes direction.
Pre-roll machines and joint rollers
Commercial joint rolling machines fill pre-rolled cones in batches rather than rolling paper by hand. The listings include several Rocket Box units, an STM Canna LaunchPad C listed as "Like New – Only Used Twice", commercial grinders from STM, and a Sorting Robotics Stardust kief coating machine. Ask for the cone sizes the machine was set up to fill and whether the matching filling trays come with it, because a joint roller without the right trays for your cones is not ready to run. The pre-roll and grinder equipment collection carries new machines and the cones and accessories they need.
| Listing | Condition | Location |
|---|---|---|
| Revolution Grinder RV-STM-1 | Used | MD |
| Rocket Box 1.0 | Used-Like New | St. Peters, MO |
| Rocket Box 2.0 | Used-Like New | Mancelona, MI |
| Rocket Box 2.0 Pre-Roll Machine | Used-Like New | St. Peters, MO |
| Sorting Robotics Stardust Kief Coating Machine | Used-Like New | Los Angeles, CA |
| STM Canna LaunchPad C | Like New – Only Used Twice | Ballwin, MO |
| STM Revolution Commercial Grinder | Used | Mount Orab, OH |
Extraction and lab equipment
Extraction listings cover supercritical CO2 systems from Apeks and MRX, a complete ethanol extraction lab, solventless separators from Liro and Hashtek, a Resinator XL, a GreenBroz Alchemist trichome extractor and a Triminator 25-ton rosin press. Systems that run under pressure should arrive with their documentation, and anything that held solvent or product should come with a record of how it was cleaned. The lab group includes an Agilent HPLC, a SCIEX DuoSpray unit, vacuum pumps, a vacuum oven, a recirculating chiller and ultra-low and explosion-proof freezers. One Agilent dry scroll pump is listed as needing a rebuild, which is worth knowing before it reaches your bench. For new extraction gear and solvents, see the extraction equipment collection.
Edibles, filling and packaging lines
The biggest group of listings is production equipment: chocolate tempering and melting from Savage Bros., gummy cooking and depositing systems, a pasteurizer, vape cartridge fillers from Vape-Jet and Thompson Duke, and complete filling, capping and labeling lines. Lines like these are usually sold as a set from one facility, so ask whether conveyors, accumulation tables and labelers were run together and whether their controls and change parts are included.
Selling or consigning your own grow equipment
If a room is downsizing, upgrading or closing, the equipment in it has more value working in someone else's facility than sitting in storage, where it keeps depreciating.
There are four common ways to sell used equipment: selling it yourself, an auction, a broker, or consignment. An auction moves a whole facility quickly but leaves the price to whoever bids that day. Selling it yourself keeps every dollar and costs you the time of finding buyers, answering questions and arranging freight. Consignment sits between them. You keep ownership until a buyer commits, a third party markets the unit to buyers you would not reach yourself, and the fee comes out of the proceeds. It usually takes longer than an auction and tends to return more, which suits owners who do not need the floor space cleared by Friday.
To list equipment in the GrowersHouse marketplace, open the Sell My Equipment form on the marketplace page and describe the make, model, age and condition. Our team helps verify condition and history, presents the equipment to growers, facility operators and industry partners, and coordinates logistics once a buyer commits. The more you send at the start, the faster a listing moves:
- Nameplate photos with model and serial number
- Year it went into service, run hours and the reason it is being sold
- Clear photos from several angles, plus a power-on video
- Manuals, service logs, and any spare parts, filters or trays that go with it
- For lab and extraction equipment, a cleaning or decontamination record
If you are re-planning a room rather than closing one, our guide on how to design a commercial medicinal flower facility covers layout, HVAC and lighting decisions, which helps decide what to keep and what to consign.
FAQs
Short answers to the questions growers ask most often about used and consignment cultivation equipment.
Where can I sell used grow equipment?
You can list it in the GrowersHouse Consignment Equipment Marketplace through the Sell My Equipment form on the marketplace page. Describe the make, model, age and condition, and the team helps verify it, presents it to growers and partners in its network, and coordinates shipping once a buyer commits.
How does equipment consignment work?
With consignment, you keep ownership while a third party markets the equipment, and you are paid once it finds a buyer, less the consignment fee. In this marketplace, your unit appears with its price, condition and location, and interested growers inquire through GrowersHouse. Contact our team for the terms that apply to your equipment.
Is used grow equipment worth it?
It is when the history is known and the unit matches your room. Used equipment arrives faster and costs less than new, and a matching model simplifies spare parts. It is a weaker choice when a warranty matters to you, when an older LED fixture falls well below current efficiency, or when a machine with many wear parts has no service records.
Are used or refurbished LED grow lights reliable?
A quality LED fixture is rated to keep 90% of its output for tens of thousands of hours, so one with a few seasons on it can have years of useful life left. Ask for run hours, check the lenses and connectors, and run it before you rely on it. Refurbished fixtures have been repaired and tested before resale, while consignment fixtures are offered as described by their owner.
Is there used grow equipment near me?
Every listing shows the city and state where the equipment sits, and the State filter on the marketplace page narrows results to your region. Current listings sit in states such as Missouri, Oregon, Oklahoma, Maryland and Michigan. A nearby unit saves freight on heavy pieces like flood tables and HVAC.
