1. Introduction to Quonset Greenhouses

If you're looking for a sturdy and dependable greenhouse structure, a Quonset Greenhouse may be just what you need. This type of greenhouse is characterized by its unique design, which utilizes curved galvanized steel tubing to create a semi-circular shape. It is a popular choice for commercial growers and hobbyists due to its durability, affordability, and versatility. In this blog, we'll take a closer look at the benefits of using a Quonset Greenhouse, as well as its design and structure, sizing options, and accessories. Lastly, we'll help you determine if a Quonset Greenhouse fits your growing needs.

2. Benefits of Using a Quonset Greenhouse

Quonset greenhouses have numerous benefits when it comes to growing plants. As mentioned earlier, their freestanding design lets in the most amount of sunlight, providing ideal growing conditions for plants. Additionally, the high pitch and dome shape allow for natural snow and rain shedding, ensuring the structural integrity of the greenhouse. Another advantage is that the center purlins on top of the bows help prevent poly sag and wear, making the greenhouse more durable. Furthermore, they are easy to heat and work well on hillsides, maximizing the amount of sunlight they receive. While the growing area near the side walls is somewhat restricted, Quonset greenhouses are still suitable for producing most crops. Overall, Quonset greenhouses provide an affordable and efficient solution for year-round gardening, making them an excellent choice for plant lovers everywhere.

3. Design and Structure of a Quonset Greenhouse

The design and structure of a Quonset greenhouse is a critical factor in its efficiency and durability. These greenhouses are typically made from galvanized structural steel tubing, which makes them virtually indestructible. The arch shape of the Quonset design allows for maximum airflow and structural strength. There are two basic designs: one with no sidewalls extending to the ground and the other with an arch forming the sidewalls. Notably, Quonset greenhouses are only available in sizes 20 feet wide and 20-145 feet long, with a center height of 12 feet, and the sidewalls are straight. Because of their sturdy construction, Quonset greenhouses are a popular option for commercial use.

4. Materials Used in Quonset Greenhouses

In Quonset greenhouses, high-grade galvanized steel tubing is the primary material used for the structure. The steel tubing is engineered to withstand wind and snow, making it perfect for all seasons. Frames are made from galvanized structural steel tubing. Other materials used in Quonset greenhouses include PVC or metal pipe, clamp fittings, and polyethylene tunnels. The choice of materials will depend on the size of the greenhouse and its intended use. With the right materials, a Quonset greenhouse can last for years and provide a safe haven for your plants to grow.

5. Uses of Quonset Greenhouses

One of the main advantages of a Quonset greenhouse is its versatility, making it suitable for a variety of uses. A Quonset greenhouse can function as a propagation, growing, or wintering house. It's also suitable for overwintering plant material, allowing you to keep your plants safe and healthy during the colder months. While Quonset greenhouses are not ideal for all crops due to the restricted growing area near the side walls, they can still be used for the production of most crops. Ultimately, the uses of a Quonset greenhouse are limited only by your imagination and needs. Whether you're starting a small home garden or running a commercial plant-growing business, a Quonset greenhouse can provide an excellent solution for your growing needs.

6. Sizing Options for Quonset Greenhouses

When it comes to sizing options for Quonset greenhouses, there are various choices available. The length and width of the structure can be customized to suit the grower's needs, with frames available from 12' to 30'. The 30'x60' size is excellent for smaller commercial greenhouse growers, while the 30'x48' frame is almost identical but slightly smaller. The greenhouse length should be determined by the number of plants the grower intends to cultivate, with most 6-inch pot plants requiring a minimum of 1 square foot of space. A Quonset style greenhouse is available in sizes ranging from 20 feet wide and 20-95 feet long. However, growers can contact the manufacturer for additional sizing options and customization. Ultimately, a Quonset greenhouse size depends on the grower's requirements and available space.

7. Quonset Greenhouse Accessories

Once your Quonset greenhouse is set up, you may want to consider various accessories for optimal functionality. One such accessory is a ventilation system, which helps regulate temperature and airflow. Another is a misting system, which provides the necessary moisture to plants. Other accessories may include shelves, benches, and hanging systems for growing equipment. Additionally, lighting systems can be integrated for year-round growth. With these accessories, a Quonset greenhouse becomes an all-inclusive growing environment.

8. Covering Your Quonset Greenhouse

When it comes to covering your Quonset greenhouse, there are several options available. You can choose from poly covers, shade cloths, or polycarbonate corrugated or twin wall covers. It's important to note that covers are extra and the size and type of cover you choose will depend on factors such as your desired shade percentage and the crop you will be growing. Additionally, you can use our shade cloth calculator to create a custom size, color, and shade percentage to fit your specific needs. Overall, the covering you choose will play a significant role in providing all-year protection for your plants by ensuring optimal light, air circulation, and temperature inside your Quonset greenhouse – so choose wisely!

9. Construction of Quonset Greenhouses

When it comes to constructing a quonset greenhouse, the process heavily relies on the design and structure chosen. As previously discussed, several sizing options and accessories are available to customize your greenhouse to fit your specific needs. However, the construction process typically involves using Allied's Gatorshield galvanized steel tubing and Kee Klamp fittings to create the arched frame. From there, the end walls and door can be added using wood or metal framing, and the greenhouse can be covered with either double polyethylene or glass/acrylic panels. It's important to consider your area's climate and weather conditions when choosing a covering type, as well as ensuring proper ventilation to prevent overheating. While constructing a quonset greenhouse may require some DIY skills, the benefits of having a cost-effective and long-lasting structure for growing plants make it worthwhile.

Quonset greenhouses are a great option for those looking for an affordable, sturdy, and easy-to-construct greenhouse.
