Is a Hoop House Greenhouse as Good as a Greenhouse?

Hoop House Greenhouse

A Hoop house greenhouse is typically constructed using a series of metal hoops or PVC pipes that are covered with a layer of greenhouse plastic. While they can be effective at protecting plants from the elements and extending the growing season, they are typically less durable and less insulated than permanent greenhouse structures.

A hoop house greenhouse can be a cost-effective and practical alternative to a traditional greenhouse, but it may not provide the same level of control and insulation as a permanent greenhouse structure.

Permanent greenhouses are typically made from glass or polycarbonate panels and have better insulation, allowing for greater control over temperature, humidity, and airflow. They also provide more protection from pests and other environmental factors.

If you are looking for a cost-effective option that can be easily assembled and disassembled, a hoop house greenhouse may be a good choice. If you require more precise control over your growing environment, a permanent greenhouse may be a better option.

How Much Does It Cost to Build a Hoop Greenhouse?

The cost of building a hoop greenhouse can vary depending on a number of factors, such as the size of the greenhouse, the materials used, and the location.

In general, a basic hoop greenhouse can cost anywhere from a few hundred to a few thousand dollars. The main expenses are typically the materials for the hoops (such as PVC pipes or metal conduit), the greenhouse covering (such as greenhouse plastic or polycarbonate panels), and any additional materials for the foundation and framing.

Other costs to consider include irrigation systems, heating and cooling systems, ventilation, and other accessories like shelving or benches. These costs can add up quickly, but they are also not always necessary depending on the intended use and climate of the location.

To get a more accurate estimate, it is recommended to consult with a greenhouse builder or supplier who can provide a detailed cost breakdown based on your specific needs and location.

How Much Warmer is it Inside a Hoop Greenhouse?

The temperature inside a hoop house can vary depending on several factors such as the external temperature, the amount of sunlight and ventilation, the type of insulation, and the moisture level. However, in general, a hoop house can be expected to be several degrees warmer than the outside temperature during the day, and several degrees cooler at night.

The amount of warming will depend on several factors, including the size of the hoop house, the type of cover material used, and the amount of sunlight available. On average, a properly constructed and maintained hoop house can be expected to maintain a temperature that is 5-10 degrees Fahrenheit warmer than the outside temperature during the day.

It is worth noting that this is just an estimate, and the actual temperature inside a hoop house can vary depending on a range of factors, including the specific design and construction of the hoop house.

What Temperature Should a Hoop House Greenhouse Be?

The temperature inside a hoop greenhouse can vary depending on a number of factors such as the outside temperature, the amount of sunlight, and the type of plants being grown. However, a general rule of thumb is to aim for a daytime temperature range of 70-80°F (21-27°C) and a nighttime temperature range of 60-70°F (15-21°C) during the growing season.

How Long Does Hoop House Plastic Last?

The lifespan of hoop house plastic can vary depending on several factors such as the quality of the plastic, the intensity of UV exposure, and the frequency of use.

On average, a high-quality, UV-treated polyethylene plastic covering for a hoop house can last for around 3-5 years with proper care and maintenance. However, some growers have reported that their plastic coverings have lasted for up to 10 years with careful handling and storage during the off-season.

It’s important to note that environmental factors such as wind, hail, and heavy snow can damage or reduce the lifespan of the plastic covering. Additionally, exposure to high temperatures and sunlight can cause the plastic to become brittle and degrade more quickly.

Regular maintenance such as cleaning the plastic coverings and repairing any tears or holes can also help prolong their lifespan.

How Do You Heat a Hoop House Greenhouse in the Winter?

There are several ways to heat a hoophouse in the winter, depending on your budget and the size of your hoophouse.

Here are a few options:

Passive Solar Heating… One way to heat a hoophouse is to use passive solar heating. This method involves using the sun’s energy to heat the hoophouse during the day, and then trapping that heat inside the hoophouse by closing the doors and vents at night. To maximize the amount of sunlight that enters the hoophouse, consider using a clear or translucent covering.

Insulation… Insulating your hoophouse can help to retain heat and prevent heat loss. You can use materials like bubble wrap, thermal blankets, or straw bales to insulate the walls, floor, and roof of your hoophouse.

Heating Systems… Another option is to use heating systems to keep your hoophouse warm. You can use electric heaters, propane heaters, or wood stoves to generate heat. However, keep in mind that these heating systems can be expensive to operate, and you’ll need to ensure that your hoophouse is well-ventilated to prevent the buildup of carbon monoxide.

Geothermal Heating… If you have the budget, you can also consider installing a geothermal heating system. This involves using underground pipes to circulate warm water or air into the hoophouse. Geothermal systems are highly efficient and can provide consistent, reliable heat throughout the winter. However, they can be expensive to install and require specialized expertise to set up.

How Do You Ventilate a Hoop House?

Ventilation is important in a hoop house to regulate temperature, humidity, and air quality.

There are several ways to ventilate a hoop house:

Roll-up Sides… Many hoop houses have roll-up sides made of greenhouse plastic or shade cloth. These can be opened to allow for natural ventilation. A rope and pulley system can be used to roll the sides up and down.

End-wall Vents… Can be installed to allow for air to flow through the hoop house. These can be manually opened or closed or automated with a thermostat or humidity sensor.

Ridge Vents… Can also be installed at the peak of the hoop house roof that allows hot air to escape. This can be combined with roll-up sides for maximum ventilation.

Exhaust Fans… Adding one or two at one or both ends of the hoop house to actively move air in and out. These can be manually operated or automated with a thermostat or humidity sensor.

It’s important to have a balance between intake and exhaust ventilation to prevent hot spots and ensure proper air circulation. It’s also important to consider the size of the hoop house, the number of plants or animals inside, and the climate in your area when deciding on ventilation options.

What Size PVC is Best for a Hoop House?

The size of PVC pipe you should use for a hoop house depends on several factors such as the desired height of the structure, the width of the hoop house, the expected wind and snow loads, and the spacing of the hoops.

In general, the most commonly used PVC pipe sizes for building hoop houses are 1/2-inch, 3/4 inch, and 1 inch in diameter. 1/2 inch PVC pipe is commonly used for low tunnels and smaller hoop houses, while 3/4 inch and 1 inch PVC pipes are used for larger hoop houses and structures that require more strength and durability.

When selecting the PVC pipe size for your hoop house, you should consider the weight of the covering material (such as greenhouse plastic), the spacing between the hoops, and the expected snow and wind loads in your area. It’s also important to make sure that the PVC pipes you choose are UV resistant and suitable for outdoor use.
