There are so many advantages to having your very own greenhouse. You can enjoy fresh vegetables throughout a longer growing season and save money on groceries. Thankfully, building a greenhouse from scratch doesn’t have to cost a fortune. You can build a DIY greenhouse in your own backyard in a few easy steps without the use of costly materials. You can buy everything you need at your local hardware store for less than one hundred dollars.
- (8) 10 1/2 ft. pieces of PVC pipe
- (14) 18-in. pieces of rebar
- 25-ft. roll of plastic sheeting
- Duct tape
- Scrap 2 x 4s
Step One: Measuring the Space
As you can see in the video, the greenhouse is built right on top of your garden. Measure out a rectangular patch of dirt that’s about 10 feet long and 6 feet wide. Plow the field and plant the seeds of your choice in the ground.
Step Two: Hammer in Your Rebar
Now it’s time to lay the foundation for your greenhouse. Use a hammer to drive the rebar two-thirds of the way into the ground at a slight angle. Use the rebar on both sides of your garden and spread out the pieces in equal increments. You should have seven 18-in. pieces on either side of the garden.
Step Three: Building the Structure
Place your PVC pipe over the end of the rebar and bend the pipe in the shape of an arch until it fits into the rebar on the opposite side of your garden. When you’re done, you should have seven rows of PVC pipe resembling a small tunnel. Lay the last piece of PVC pipe at the top going long ways. Use duct tape or zip ties to secure the last piece of PVC pipe to the other seven.
Step Four: Cover the Space with Plastic
Unroll your plastic sheet and place it over the PVC structure you just made. Pull the plastic sheet down on all sides until it’s taut. Use a few scrap pieces of wood to secure the ends of the plastic sheet.
Congratulations. You’ve just built your very own greenhouse with just a little bit of money and time. Of course, this type of greenhouse won’t be as sturdy as those that are made with stone, wood, and concrete. But this structure will still protect your garden from harsh weather and cold temperatures. You’ll probably want to take the greenhouse down before the dead of winter arrives. Considering how easy it is to build, you can always put it back up again in the spring.
Naturally, this kind of greenhouse will not withstand extreme conditions or outlast stronger structures. Some areas of the greenhouse might need replacing after a few months depending on the weather and other demands placed on it. Despite its limitations, this is by far the easiest and most affordable way to build a greenhouse. Happy planting!
