Green or Clear Greenhouse Cover: Making the Right Choice
When it comes to covering your greenhouse, the choice between green and clear plastic can significantly impact your plants' growth and overall greenhouse performance. In this blog, we'll explore the advantages and disadvantages of both options and help you decide which is the best plastic to cover your greenhouse.
Is it Better to Have a Green or Clear Greenhouse Cover?
-
Green Greenhouse Cover:
-
Advantages:
- Diffused Light: Greenhouse covers with a green tint provide diffused light, which scatters sunlight evenly throughout the greenhouse. This helps prevent hot spots and reduces the risk of sunburn on plants.
- Shade: The green tint offers some shade, making it ideal for sun-sensitive plants or during periods of intense sunlight.
- Temperature Regulation: Green plastic can help moderate temperature fluctuations by reducing heat buildup during the day.
-
Disadvantages:
- Reduced Light: Green covers may reduce the overall light intensity in the greenhouse, which can affect plant growth, especially during cloudy days or in low-light conditions.
- Slower Growth: Some plants may grow slightly slower under green plastic due to reduced light levels.
-
-
Clear Greenhouse Cover:
-
Advantages:
- Maximum Light: Clear plastic allows the maximum amount of sunlight to penetrate the greenhouse, promoting faster growth and higher yields.
- Warmth: Clear covers capture more heat, creating a warmer environment, which can be advantageous during colder seasons.
- Versatility: Clear plastic is versatile and suitable for a wide range of plants and growing conditions.
-
Disadvantages:
- Potential Sunburn: The intense sunlight under clear plastic can lead to sunburn on sensitive plants without proper shading or ventilation.
- Temperature Extremes: Clear covers can result in temperature extremes, with high daytime temperatures and cooler nights.

What is the Best Plastic to Cover a Greenhouse?
The best plastic for your greenhouse largely depends on your specific needs and the types of plants you're growing. Consider the following factors when making your choice:
-
Plant Type: Some plants thrive in diffused light and benefit from a green cover, while others require maximum sunlight and do better under clear plastic.
-
Climate: Your local climate, including temperature, sunlight hours, and seasonal variations, should influence your decision. Clear plastic may be ideal for colder climates, while green plastic can provide shade in hot, sunny areas.
-
Goals: Determine your goals for greenhouse gardening, such as maximizing plant growth, extending growing seasons, or protecting sun-sensitive crops.
-
Shade Requirements: Assess whether your plants require partial shading. If so, a green cover may be more suitable.
Should You Use Clear Plastic for a Greenhouse?
Clear plastic is a versatile option that works well for many greenhouse applications, especially if you prioritize maximum light and warmth. However, if you're growing sun-sensitive plants or in regions with scorching summers, you may need to employ shading or ventilation solutions to prevent sunburn and temperature extremes.
In conclusion, there's no one-size-fits-all answer to whether green or clear plastic is better for a greenhouse. Your choice should align with your specific growing conditions, plant preferences, and climate. Careful consideration of these factors will help you make an informed decision and create an ideal environment for your greenhouse gardening success.
