A hoop house is generally defined as a simple greenhouse and is commonly used for season-extension, allowing crops to thrive and be cultivated well after their normal growing season. It is generally constructed using basic materials such as pvc pipe reinforced with rebar for the frame and a plastic sheet to cover the structure.
Step 1: Supplies
First figure out the dimensions of the greenhouse you are constructing. A hoop house can vary in size depending on your needs. The one we are working with in this description is approximately 13' long x 10' wide x 6' tall.
What you will need:
*PVC pipe (in our case we used 3/4" pipe)
*PVC T-fittings( you may need 2 or 3)
*Plastic greenhouse liner
*Wooden planks(the length and width of your greenhouse)
*Optional: Wood( if you choose to build door frames)
Step 2: Door Mounting and End Frame
In this step we're starting by cutting our piping to our desired measurement specifications. We added the 'T' fittings to the center of our arches, directly over the end frames. Next we'll be securing the door and rear frame by running an arched cross beam over each frame and securing it to the door with zip ties followed by burying the ends at least a foot deep in the ground. Finally we'll connect our length-wise crossbeam.
Step 3: Running Cross-Sections or "Ribs"
In our example we measured the distance between our cross-sections at 4' apart. Again, this can vary depending on your measurements and support needs. We secured the ribs to the cross-beam using our zip ties followed burying the ends as we did in the previous step. You can also add additional support by connecting a vertical beam at the center of the frame (also optional).
