Greenhouses allow you to extend your growing season and have more plentiful harvests. With proper construction and plant selection you can grow all year long. There are a countless number of designs that you can find online. If you're like us, you've spent months researching greenhouse designs that would be both economical and easy to build.
Hoop greenhouses have several benefits over other greenhouse plans for effective growing all year long. We build our hoop houses on the coast of North Carolina which are prone to high winds and rain from hurricanes and tropical storms.
This free greenhouse guide was put together after building several greenhouses on our property. It will give you detailed plans on building a DIY greenhouse that minimizes cost and maximizes ease of build. It is our hope that you find these free greenhouse plans helpful.
How many plants do you want to grow? How much room do they take up? Do you want to bring equipment into your greenhouse? These are questions you need to ask yourself before you get started. Make sure you build a greenhouse with a size that best fits your needs. These greenhouse plans are for both a 6 foot wide low tunnel greenhouse and a 10-24 foot wide high tunnel hoop house.
The Low Tunnel Greenhouse stands 4 foot high and will be 6 foot wide. The low tunnel hoop house is a great choice when planting low-growing plants, including:
|Peas||Kale||Other Low Growing Plants|
The high tunnel greenhouse plan can be built anywhere from 10-24 feet wide and approximately 6.5 ft (easily adjustable to 14 ft or higher for 20-24 feet wide) high structure. A high tunnel quick hoop house is an ideal choice if you plan to have a walk-in greenhouse. These are great if you want to have a wide variety of plants or want to be able to work inside of your hoop house.
In the heat of summer or climates in hardiness zone 8 or higher, greenhouse ventilation is critical. If you don't want your plants to cook in the heat, we absolutely want roll-up sides with a hand crank. This allows you to easily manage the venting. We also recommend roll-up sides with a hand crank for all low tunnel hoop houses as it allows for easy access to your plants from the sides.
During the intense summer heat, we may need to throw a shade cloth on top of our greenhouse to keep it cool and reduce the solar radiation. In the frigid winter, we can consider adding another layer of greenhouse film for extra insulation. Check out this great video from Dr. Nate Storey at Bright Agrotech on double layer greenhouses if you live in an especially cold environment.
First, pick an area that is flat and not prone to flooding (More information can be found at Selecting the Ideal Location for your Greenhouse). If you have an existing greenhouse on your property you want to make sure it is at least 8 feet away from existing one.
Tools Needed (See the complete list of Greenhouse Tools)
Our instructions assume ground posts and bows every 4 feet. We sink the ground posts 2 feet into the ground, allowing for higher tunnels and stronger frames. 20-24ft houses in high wind areas should make deeper ground posts and secure the plastic lock channel with extra screws.
