Understanding High Tunnel Farming
High tunnel farming is a method of crop production that utilizes large, semi-circular structures covered with plastic film. These structures, often called hoophouses, create a controlled environment that extends the growing season and protects crops from harsh weather conditions. In Lancaster, PA, where the climate can be unpredictable, high tunnels have become an invaluable tool for farmers looking to increase their productivity and crop quality.
The Importance of Plastic Selection in High Tunnels
The type of plastic covering used in a high tunnel plays a crucial role in determining the success of crop production. Different plastics offer varying levels of light transmission, heat retention, and UV protection, all of which directly impact plant growth, disease resistance, and overall yield. For Lancaster growers, selecting the right plastic can mean the difference between a bountiful harvest and a disappointing season.
Types of Plastic Coverings for High Tunnels
Let’s explore the various types of plastic coverings available for high tunnel farming and their unique properties:
- Polyethylene (PE) Films: These are the most common and cost-effective options. They come in different thicknesses and can be treated to enhance specific properties.
- UV-Transparent Films: These films allow more ultraviolet light to penetrate, which can boost plant growth and flavonoid production in certain crops.
- Infrared (IR) Films: Designed to trap heat, these films are excellent for maintaining warmer temperatures inside the tunnel during cooler months.
- Anti-Condensation Films: These prevent water droplets from forming on the inside of the tunnel, reducing the risk of disease and improving light transmission.
- Diffused Light Films: These scatter incoming light, providing more uniform illumination throughout the tunnel and reducing plant stress.
Each type of plastic offers unique benefits, and the best choice often depends on the specific crops being grown and the local climate conditions in Lancaster, PA.
Impact of Plastic Selection on Crop Health
The choice of hoophouse plastic can significantly influence the health of your crops in several ways:
Light Transmission and Plant Growth
Different plastics allow varying amounts and types of light to pass through. UV-transparent films, for instance, can increase the production of beneficial compounds in plants. In basil cultivation, research has shown that UV-transparent films can lead to a 30% increase in biomass compared to standard plastics. This is particularly relevant for Lancaster farmers looking to maximize their herb production.
Temperature Regulation
Heat-retaining films can help maintain optimal temperatures inside the tunnel, especially during Lancaster’s cooler months. This can lead to faster growth rates and earlier harvests, giving local farmers a competitive edge in the market.
Disease Management
Certain plastic types can help manage diseases by altering the light spectrum or reducing condensation. For example, films that reduce humidity can help control downy mildew, a common problem in Lancaster’s vegetable crops.

Boosting Crop Yield with the Right Plastic
The impact of proper plastic selection on crop yield cannot be overstated. Here’s how the right covering can lead to increased production:
Extended Growing Season
“Proper plastic selection in hoophouses can extend the growing season by 2-3 months in temperate climates.”
In Lancaster, PA, where the growing season is limited by cold winters, the right high tunnel plastic can extend the productive period by several months. This allows farmers to harvest crops earlier in spring and later into fall, significantly increasing annual yield.
Improved Light Diffusion
Diffused light films scatter sunlight more evenly throughout the tunnel. This reduces shadows and ensures that lower leaves receive adequate light, leading to more uniform crop growth and higher overall yields.
Enhanced Environmental Control
By selecting plastics with specific properties, growers can create an ideal microclimate within their high tunnels. This level of control allows for optimized growing conditions, resulting in healthier plants and increased production.
Case Study: Basil Cultivation in Lancaster High Tunnels
Recent research conducted at Penn State University has shed light on the significant impact of plastic selection on basil cultivation in high tunnels. The study, which is particularly relevant to Lancaster’s agricultural community, compared the effects of UV-transparent and UV-blocking films on basil growth and quality.
Key Findings:
- Basil grown under UV-transparent films showed a 30% increase in biomass compared to those under UV-blocking films.
- The concentration of valuable phenolic compounds and flavonoids was significantly higher in basil grown under UV-transparent conditions.
- UV-transparent films led to improved plant architecture, with more branching and larger leaf areas.
These findings highlight the potential for Lancaster farmers to significantly boost their basil production and quality through careful selection of high tunnel plastics.
Sustainable Farming Practices in High Tunnels
As we strive for more sustainable agricultural practices, the selection of high tunnel plastics plays a crucial role. Here’s how proper plastic choice contributes to sustainability:
Resource Efficiency
By creating an optimized growing environment, high tunnels with appropriate plastics can reduce water usage and minimize the need for pesticides and fertilizers. This is particularly important in Lancaster, where conservation of natural resources is a priority.
Energy Conservation
Heat-retaining plastics can reduce the energy required to maintain optimal temperatures in high tunnels, especially during Lancaster’s colder months. This leads to lower energy costs and a reduced carbon footprint.
Waste Reduction
Choosing durable, long-lasting plastics can minimize waste and reduce the frequency of replacements. Some modern plastics are also recyclable, further contributing to sustainability efforts.
