  • Typically they are attached to the ground with ground anchor or ground stakes. These are galvanized steel pipes that are just a bit wider than the hoops. The hoops slide into them and then you drill them out and bolt them together.

  • The quonset style greenhouses can all be made up to 12’ tall. You will do this by using longer ground stakes.

    The gothic style are typically fixed height, but customizations are available. Just let us know what you are trying to accomplish and we will work with you to get what you are needing.

  • We offer two ways to keep your greenhouse cool. The most popular is with a side roll up system. This includes a handle for each side and the pipe that the plastic will attach to. Then you simply crank the pipe up and down allowing fresh air inside. This is low tech, simple and very effective method for moving air through a greenhouse.

    The other way is to use powered fans and fresh air intakes. The benefit here is that you keep your greenhouse sealed up better, but you do need a power source.

  • Ventilation is the most important. Shade cloth is also very helpful at cooling. Weed barrier fabric is great to have. Please contact us if you have any questions about how to outfit your greenhouse.

Which style is best for me?

There are a few of factors to consider when picking the right greenhouse for you.

Budget

  • The quonset style offers the best value in terms of price per sq. ft. They are affordable, reliable greenhouses that will help you grow more than you ever have. The rounded design of our Quonset style is fantastic in windy locations.

Your location

  • If you live in a climate that receives serious snowfall every year, a Gothic Style greenhouse is recommended. They are made with larger diameter pipe and include trussing systems.

How will you use your greenhouse?

  • If you are a market gardener or for any reason you want to be able to move your greenhouses around your property, then Caterpillar Tunnels are an excellent choice. They are designed to be set up and taken down with ease.
