Oklahoma's Ever-Changing Weather: Building Resilient Greenhouses

Oklahoma, often characterized as a state of diverse landscapes and dramatic weather variations, poses unique challenges and opportunities for greenhouse owners and growers. To maximize greenhouse efficiency and productivity in this region, it's essential to comprehend the intricacies of Oklahoma's climate and tailor your greenhouse accordingly.

The Four Seasons of Oklahoma

1. Hot and Dry Summers:

Oklahoma experiences blistering summers characterized by high temperatures, abundant sunlight, and minimal rainfall. The arid climate can subject greenhouse structures to intense heat, which, if not managed effectively, can adversely affect plants and increase cooling costs.

To address this, greenhouses in Oklahoma must incorporate:

  • Shading Systems: Deploying shading systems, such as retractable shade cloth or roll-up sidewalls, helps mitigate excessive solar radiation, preventing heat stress in plants and reducing cooling expenses.

  • Ventilation: Proper ventilation is crucial to ensure adequate airflow and temperature control within the greenhouse. Exhaust fans, roof vents, and side vents can help expel hot air, maintaining a cooler internal environment.

  • Cooling Systems: Evaporative cooling systems, like wet wall pads, can effectively reduce temperatures inside the greenhouse, enhancing plant growth and comfort for workers.

2. Unpredictable Springs and Autumns:

Oklahoma's transitional seasons can be quite unpredictable, with temperature fluctuations and sudden weather changes. This variability necessitates a greenhouse design that accommodates both heating and cooling needs, depending on the specific conditions.

  • Thermal Curtains: Installing thermal curtains provides insulation during cooler nights and can be retracted during warmer days, ensuring temperature stability.

  • Heating Systems: Efficient heating systems, such as gas or electric heaters, are essential for maintaining optimal temperatures in early spring and late autumn when outdoor conditions are less favorable.

3. Mild Winters with Occasional Cold Snaps:

Oklahoma typically experiences mild winters, but occasional cold snaps can bring freezing temperatures. To keep crops thriving through the winter, especially sensitive plants or those with longer growth cycles, greenhouses need:

  • Heating Solutions: Adequate heating systems become vital during colder periods to prevent frost damage and maintain a suitable environment for plant growth.

  • Insulation: SolaWrap stands out as an insulation solution for Oklahoma's greenhouses:

    1. Energy Efficiency: SolaWrap features a unique bubble design that provides exceptional insulation. Its R-Value of 1.7 ensures that your greenhouse maintains a stable temperature, reducing the need for excessive heating or cooling. This energy-efficient feature is invaluable in Oklahoma's climate, where temperature fluctuations can stress plants.

    2. UV Protection: Oklahoma's strong sunlight can be both a blessing and a challenge for greenhouse growers. SolaWrap offers UV protection, shielding your plants from excessive sun exposure, preventing sunburn, and promoting healthier growth.

    3. Durability: SolaWrap's ability to withstand heavy snow loads of up to 120 lbs per square foot makes it ideal for Oklahoma's occasional winter storms. Its wind rating of 100 mph, with a track record of surviving 135 mph winds in Alaska, ensures that your greenhouse remains intact during severe weather.

    4. Longevity: Unlike some greenhouse films that yellow and become brittle over time, SolaWrap maintains its flexibility and durability. Its 10-year warranty against UV degradation is a testament to its long-lasting performance, even under the Oklahoma sun.

    5. Diffused Light: SolaWrap's 83% transparency and up to 83% diffused light provide the perfect balance for optimal plant growth. It ensures that your plants receive adequate sunlight without the risk of overheating.

    6. Versatility: SolaWrap's flexibility allows it to be easily rolled up inside wall curtains, providing versatility in greenhouse design. This feature is particularly valuable for adjusting ventilation during Oklahoma's changing seasons.

4. Springtime Storms and Tornadoes:

Oklahoma is located within the infamous "Tornado Alley," which means it's susceptible to severe storms and tornadoes, particularly in spring. Greenhouses need to be structurally sound and equipped to withstand extreme weather events:

  • Wind Resistance: Reinforced greenhouse structures and anchoring systems are essential to prevent damage during high winds. Windbreaks or natural barriers can also provide protection.

  • Storm Preparedness: Developing an emergency plan that includes steps to secure the greenhouse, move valuable equipment, and protect crops is crucial for minimizing storm-related damage.

Efficient Greenhouse Features for Oklahoma's Climate

To ensure greenhouse efficiency and productivity in Oklahoma's variable climate, consider implementing the following features:

  • Automated Climate Control: Investing in automated systems that regulate temperature, humidity, and ventilation based on real-time data can help maintain optimal growing conditions year-round.

  • Proper Insulation: Effective insulation materials and techniques, such as double-layer polyethylene film, thermal curtains, and energy-efficient glazing, contribute to temperature stability and reduced energy costs.

  • Weather Monitoring: Install weather monitoring equipment to stay informed about incoming weather patterns and make necessary adjustments to protect your crops.

  • Durable Construction: Opt for durable greenhouse materials and construction methods that can withstand strong winds and extreme weather events.

  • Back-Up Power: Consider installing backup power sources like generators or battery systems to ensure essential systems continue running during power outages.

In conclusion, understanding Oklahoma's climate and its seasonal variations is essential for planning and designing an efficient and resilient greenhouse. By incorporating the right features, technologies, and contingency plans, greenhouse owners can thrive in this dynamic agricultural environment and optimize crop production year-round.
