Instructables
Picture of Hoop House
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)
* Re-bar
*PVC T-fittings( you may need 2 or 3)
*Zip ties
*Plastic greenhouse liner
*PVC saw
*Measuring tape
*Cement blocks
*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).

This is a good one, thanks for posting! One quick question: did you attach the liner to the pvc pipes in any way? (my apologies if I missed that somewhere). Also, how did you fasten the liner in an arch like that around the doorway? (sorry, i meant TWO quick questions! ;)

Awesome instructible. Would it be better to have a clear plastic for the greenhouse or is the translucent okay? Do they even make a clear liner?

I do a lot of "googling" and came across these:

You can fit the ridge pole to the cross hoops in one piece.
Wow! That looks awesome and seems fairly easy to build. :D
