Ideal for Market Gardeners, Flower Growers, and Tree Seedling Producers
The Freestanding Commercial Greenhouse is an outstanding choice for growers seeking an independent, versatile growing structure designed for durability and optimal crop production. These stand-alone greenhouses provide a reliable growing space that can adapt to a wide range of needs.
Each freestanding greenhouse operates as a self-contained unit, offering growers the flexibility to manage specific crops or environmental conditions without impacting other structures. With customizable widths and lengths, these greenhouses maximize usable growing space while enhancing crop development and operational efficiency.
Built from certified structural steel with a minimum strength of 50 ksi, freestanding greenhouses are 52% stronger than standard commercial steel tubing. Their oval or gothic designs minimize wear on polyethylene films, ensuring a durable, long-lasting environment that supports consistent production.
Freestanding greenhouses are designed with ample height and ventilation options, including ridge vents, side roll-up vents (manual or automated), and mechanical systems like fans and air circulators. These features promote superior natural ventilation and effectively manage water, ice, and snow buildup, providing an optimal growing environment year-round.
Freestanding Greenhouse Benefits:
- Versatility
- Bright Environment (90-91%)
- Height and Width: Provides a large air volume for stable conditions
- Natural Ventilation: Designed to enhance airflow efficiency
- Easy Assembly
- Self-Build Option
- Great Value: Combines affordability with high performance
What is a commercial freestanding greenhouse?
A freestanding greenhouse is a flexible and practical growing structure, ideal for growers looking to start small or manage separate growing environments. Each freestanding unit operates independently, allowing growers to tailor each structure to specific crops, climates, or growing methods.
For growers seeking versatility, freestanding greenhouses offer a cost-effective solution, especially for operations with diverse needs. Unlike gutter-connected greenhouses, freestanding models don’t rely on interconnected designs, making them easier to relocate or repurpose as needed. While this means purchasing separate structures for expansion, the independence of each greenhouse simplifies maintenance and customization for unique requirements.
New growers can begin with a single freestanding greenhouse, which provides an affordable entry point into commercial growing. As operations scale, additional units can be added to cater to new crops or expanded production. This incremental approach ensures a manageable and adaptable growing space that evolves alongside the grower’s needs and goals.
