These plans can be
tailored to fit your needs, and the size of the building is up to you.
This particular type of greenhouse is called a hoop house or high
tunnel, and utilizes PVC pipes and poly fabric sheeting or plastic
sheeting to make an extremely simple structure. The end product will
resemble a tunnel or a long arched structure.
Step by Step Instructions
for Building a Solar Greenhouse
- 7 - 20 foot ¾ inch PVC
- 1- 14 foot 2 inch PVC pipe
- 2- 12 foot 2x4
- 4- 14 foot 2x4
- 8- 10 foot 2x4
Step 1- Constructing the
This particular greenhouse
can sit directly on the ground, or you can
put a piece of plywood underneath to keep it off the ground, but it
doesn’t require a traditional foundation. This makes it much more
portable, and some would say temporary, but it doesn’t have to be
temporary if you build it well. To build you side walls, you’ll first
need to take a piece of twenty foot ¾ inch PVC pipe and bend it to form
a half circle.
The total width of this
greenhouse is should be around
twelve feet, so you’ll need to attach your PVC to a piece of wood
twelve foot long to hold it in place. Once your PVC is bent and
attached on each end, you’ll want to start building the door frame. The
frame should be between three and five feet wide so you can easily pass
through it. You’ll want to screw a piece of 2x4 on each side of the
You’ll also want to screw
another 2x4 across the top of
the door opening to hold everything in place and make your door frame.
It may also be necessary to add other bracing at angles if your frame
isn’t sturdy enough.
This will make one end of
your structure, and you
can repeat the steps for the other end if you wish to have a door on
each side. If you want the other end to be closed, then you can simply
bend your PVC to match the other side and add 2x4 vertical studs every
2 feet. These should be attached to the wood base at the bottom, and
the PVC on the top.
Step 2- Covering the Ends
Before you attach the ends
together, you’ll need to cover them with
sheeting. You should measure out a piece of plastic sheeting to
completely cover the end walls, and make sure that there is quite a bit
of plastic overlapping. Then you can stretch the plastic tight around
the wall and staple the overlapping parts to the studs and door frame
on the inside. This will seal up the ends of your greenhouse. Make sure
you cut out the plastic from around the door frame so you can still
enter the greenhouse.
Step 3- Attaching the End
Once you have built the
end walls, you’ll need to attach them together
so you can build the sides of the structure. This particular greenhouse
is 14 feet long; however you can make it any length you wish.
the ends together, you’ll want to cut two 2x4s to 14 feet long each.
These boards should be laid down on the small side, and then the end
walls should be stood upright and screwed to the end of each
You’ll need at least two
people to do this, as one person will need to
hold the end wall upright while the other screws the walls to the 2x4s.
Once the walls are stood upright and screwed to the base boards, you’ll
have a solid structure with the two ends of your greenhouse attached
You should do this step in
the location that you want to
place the greenhouse. Also, it’s important to
fasten each end wall to
the ground using stakes or fence posts to ensure that the greenhouse
doesn’t blow away. The stakes can be driven into the ground on the
inside of the greenhouse and screwed directly into the 2x4s on the end
Step 4- Constructing the
Now that you have the ends
of your greenhouse attached to each other,
you’ll now need to take your remaining 20 foot PVC pipes and build the
sides of your greenhouse. Bend each PVC pipe and secure it to the
bottom 2x4s on each side of the structure. You should place one piece
of PVC every 2 feet. After you have attached the remaining pieces of
PVC pipe, you should have the basic tunnel structure of your greenhouse.
Step 5- Attaching the Top
Now you will want to take
your 2 foot wide, 14 foot long piece of PVC
pipe and screw it to each end of your side walls at the top. This beam
should rest underneath the other pieces of PVC, and it’s recommended
that you wire this beam to each piece of PVC to keep the structure
sturdy and hold everything together.
Step 6- Covering the Rest
Greenhouse in Plastic
The final step will be to
cover the entire remaining structure in
plastic and screw or staple the plastic to the inside of the structure.
Make sure that you pull the plastic tightly around the structure and
that there are no gaps. It’s essential to seal it in completely, or you
will lose too much heat. You should now have a sealed tunnel structure,
and you’re ready to start growing plants in your solar
