How To Build A Hoop Greenhouse


A hoop greenhouse costs around $1,500 to $2,000, depending on the materials used. Most people hire a handyman to help with the project. They charge around $60 to $100 an hour, and some even charge more to do professional work. The cost of a greenhouse depends on its size, so more lights are needed for larger greenhouses. Some people choose to run water and electricity to the greenhouse, which adds to the cost. A landscaper or electrician will likely charge around $50 to $100 per hour for these services.

Polyethylene is the cheapest covering material. The material comes on rolls. Fiberglass is a stiffer alternative and costs about $0.70 per square foot. If you want a more attractive greenhouse, you can choose polycarbonate siding. Glass is the most expensive covering option, but it is also the most attractive. Glass greenhouses can cost up to $2.50 per square foot. The cost of a greenhouse depends on the materials and the labor needed.

Plastic hoop covers are inexpensive and can be built within a day. They can be knee-high or large enough to allow a person to work inside. Plastic hoops also resist frost and snow and are useful for protecting your plants from hungry animals. They also help raise daytime temperatures and reduce exposure to UV rays. If you build your own hoop house, you’ll save a lot of money over the long run.

The framing materials for your hoop greenhouse depend on your budget. Aluminum and PVC are the least expensive materials, but both materials can be expensive compared to wood. A good choice for a budget greenhouse is wood, but it is not as durable as polyethylene. Steel is the most expensive, costing between $7 and $12 per linear foot. It’s also the most durable. If you want to save money, you can even purchase a pre-installed kit for a greenhouse.


For an inexpensive and durable structure, a hoop greenhouse can be constructed from rebar, which can be found in most home improvement stores. The thickness of the rebar depends on how much UV light will pass through the greenhouse. To maximize the amount of UV protection, choose a material that is eight or twelve mils thick. This material has an AquaArmor liner that is designed to minimize punctures and tear resistance.

The trusses are attached to the hoops and are the most difficult part of the greenhouse. You can either buy trusses or make them yourself. Regardless of what type of material you use, you’ll need two-inch pvc pipes that are at least eight feet long. Make sure you get the trusses of the right length, or you can build them yourself. Whether you use rebar or polypropylene trusses, make sure that you pick materials that will withstand extreme weather conditions.

Another option for a hoop greenhouse is bamboo. Bamboo is inexpensive, but it is difficult to maintain. Bamboo is a natural, renewable material, but requires special care. Bamboo is an excellent option if you’re growing plants in a cool climate. A hoop greenhouse’s ideal temperature range is between 50 and 80 degrees. To build a hoop greenhouse, start by constructing a frame. Attach the hoops and plastic sheeting to the frame using screws. Finally, connect PVC pipes using nuts and bolts. Once the frame is complete, add the soil and seeds. A hoop greenhouse will provide protection from bugs, pests, and animals that would otherwise harm your crops.

Building a hoop greenhouse is not difficult, and it doesn’t take much time to complete. You will need wood, nails, and PVC pipe. You can also make it permanent by using steel, aluminum, or concrete, but these materials are extremely heavy. Consider using temporary materials like scrap wood or PVC pipe. They are less expensive than permanent materials and can be easily transported from one place to another.


When building a hoop greenhouse, you will need to use rebar. You will want to cut the pieces so they are about 15 inches wide by 1.5 meters long. Once the rebar is in place, you can slide the pvc pipes over the bars to create a hoop that spans the entire greenhouse. You will then need to attach the pvc pipes to the 2x6s using metal banding. Attach short pieces of metal banding to the pipe and then slide them into the frame.

First, measure the length of your hoop house. This will allow you to determine how many Purlins you need to make. You will need to measure the hypotenuse between the two outer corners to get the correct measurements. Next, mark the fourth and final corner with a stake. Once you have these two outside corners marked, measure the fourth corner. Make sure the two boards are level in both directions.

To build a hoop greenhouse, you’ll need a sunny location and a 4-by-8-foot rectangle. Start by clearing the ground in an area with at least one foot of flat land. Once you have cleared your area, place two by fours on the long sides of the garden bed. Make sure the corners are square and the sides are parallel. If you decide to purchase a kit, make sure it comes with directions and materials.

Next, lay the ground level framing. The baseboards span the entire structure, connecting each hoop and each anchor. Once these are in place, install other lumber and tie them up. You should complete the framing, including rough door openings and horizontal bracing. This will allow you to secure the plastic greenhouse in place. If you do this correctly, your greenhouse will be sturdy and stable.

Extension of growing season

Hoop houses are not difficult to build. Most designs use metal posts or bows driven into the ground and galvanized metal hoop frames. These frames are a traditional quonset style, and should be as sturdy as possible. To extend the growing season, growers should choose heavy-gauge galvanized steel pipe for the hoops, which should not exceed four feet apart. A 6-mil greenhouse grade polyethylene roof is sufficient for most growers, while a double-layered plastic roof is better for those with very cold climates.

Although this method is typically used for protecting crops from the cold, it is also a great way to extend the growing season. During the warm months of the year, it’s essential to control the temperature. A cool microclimate can prevent crops from bolting or developing bitterness. Similarly, it may be useful to increase the temperature of cool-weather crops for those with a cool climate.

A hoop greenhouse’s polyethylene is also good for winter protection. It allows light to pass, but traps heat energy. For a low tunnel, a roll of polyethylene is ample, while a taller one needs more. In addition, garden beds vary in length, so make sure to leave a few extra feet at each end. You’ll also need blocks to secure the poly in place.

As an added bonus, the hoop house can be used over multiple crops. It can also be used over cold frames for protection against frost. Although hoop greenhouses are the most effective way to extend the growing season, they aren’t the only option. Another option is a cold frame, which is essentially a bottomless rectangular box that protects plants from the cold. This method is much more cost-effective and can be used for smaller batches of crops.

Using shade

If you live in a region with little to no sunlight, you may be wondering if using a hoop greenhouse is a good idea. This structure is typically oriented with its long sides facing north and south, but some books recommend orienting them the other way around. In the South, for example, it is better to face the long sides north and east. The rows running north-south provide the best lighting and ventilation.

Once you have a plan in place, you can begin the process of building the shade structure. First, you need to determine the length of the greenhouse. You will want to cut thirty-four pieces of rebar. You should then pound each rebar piece on its outside face at intervals of two feet. Next, use the wood lathe to attach the plastic drapes to the twox6s. Then, screw short pieces of metal banding around the plastic pipe. Place them inside the frame, two feet apart.

If you decide to heat your hoop greenhouse with wood, you should plan where you will store the wood and where you will place the furnace. While most growers do not heat their hoop houses, if you do, you will need to make sure you have access to wood and an underground pipe from your furnace. This way, your greenhouse will be heated efficiently. This can save you a lot of money on heating bills, and it will keep your crops warm throughout the winter.

A hoop house is an efficient way to extend your growing season. Its height allows you to walk under the structure, which gives you more flexibility for the time of year you choose. These structures are perfect for growing food in a climate where winters can be cold and summers are hot. They can also be used for other agricultural purposes, and they are often less expensive than traditional greenhouses. The most significant advantage of a hoop house is its use year-round.
