What’s inside:
Water Resistant Construction – Easy to Clean & Maintain
Too much moisture in the air or repeated exposure to water ruins many traditional buildings, posing a real problem for grow rooms with plants that thrive in higher-humidity environments or any consistent wet conditions. Quonsets provide a few key advantages for humid or wet indoor farms:
Rust-Proof Steel
All of our Quonset huts are coated in water-repellent and rust-inhibitive Galvalume Plus so your grow room can be as humid as it needs to be.
Insulation Vapor Barriers
If needed insulation provides a vapor barrier between the humidity (or lack of humidity) outside reducing the condensation on the inside.
Commercial Grade Steel
Our buildings are made of durable, heavy-grade steel so you won’t have to worry about severe storms or frequent building repairs.
Little-to-No Maintenance
If your grow room gets dirty on the inside or out, you can just hose it down to get it clean.
100% Usable Space For HVAC, Storage & Grow Lights
- Overhead space for lighting
- HVAC system and piping
- Ventilation systems
- Added storage room
Space in grow rooms is always at a premium so having a Quonset building that has no beams, trusses or walls is a huge advantage. Oftentimes, it can be better, easier, and more cost-effective to build a new, dedicated custom grow room than to retrofit an older building.
Your building can be designed to be a full-room grow house or divided up into different rooms depending on your needs. Taking advantage of the limitless interior space can be very beneficial to growers.
A SteelMaster metal warehouse can be used as an all-in-one growing facility, extraction lab, and distribution center.
Because of the unlimited interior space, vehicles can easily access the building for loading and unloading as well as plenty of room to configure key elements of your grow room.
Cost Effective, Designed for Growth
| Pricing Factors | Standard Commercial Grow Room | Quonset Grow Room |
|---|---|---|
| Interior Finishing Required | Yes | No |
| Easily Expandable | No | Yes |
| Maintenance | Standard | Low maintenance |
| Construction Time | Standard | Quick kit assembly |
According to Buildings Guide, the average commercial building cost is between $16 and $20 per square foot.
SteelMaster offers steel buildings in a variety of sizes that are most cost-effective with widths of 80′ and under. The price of our grow buildings starts as low as $10 per square foot.
This is partly because standard commercial buildings typically require finishing in the interior and they can cost a great deal in construction labor.
Comparatively, Quonset huts only require insulation or finishing in more extreme environments or with grow rooms with strict climate control needs and because Quonset’s are delivered as prefab grow house kits, the construction takes a fraction of the time.
Additionally, SteelMaster’s metal buildings come in a variety of sizes and can be customized for grow operations of all sizes, now and into the future.
When your business expands, your building can as well—without the costly renovations. Our buildings can easily expand with extra steel panels on the existing structure allowing you to add more grow racks or supplies storage.
The lower maintenance with steel buildings also means you’ll not only get more building for a better price but it will also have cheaper long-term costs.

Quonsets for Advanced Marijuana Cultivation
With the legalization of marijuana, cultivation methods have been getting more advanced and precise. Further, the global legal marijuana market is expected to reach $146.4 billion by the end of 2025, according to Grand View Research, so cultivation companies, of all sizes, are investing large amounts into building more grow houses and many are choosing to build a “grow hut” to get an edge in the ever-more crowded market.
For Marijuana operations some key Quonset advantages include:
- Larger building sizes and expandability allow for growth, cultivation, and extraction to take place within the same building
- The strength of a steel building, security doors, and cameras all make marijuana grow operations safer and less susceptible to theft
- Grow room customizations, like roll-up doors, windows, or vents can all be configured with your Quonset hut “shell.”
