If you’re trying to buy a commercial greenhouse, you’ll have dozens of options across the USA. These range from manufacturers specializing in greenhouses and greenhouse supply on an international scale to small-scale and local builders.
In addition, many large metal building manufacturers also offer greenhouses – although they normally offer the shell and not the watering and plant-rack technology offered by greenhouse-specific manufacturers.
Many of the greenhouse manufacturers on this list stand out for specific offerings, technology, pricing, or a national level of service. Others will offer very similar products, which may only be largely differentiable in price.
The following includes some of the best commercial greenhouse manufacturers.
*Note: These commercial greenhouse suppliers are ranked in no particular order.
