Choosing the Right Greenhouse Plastic for Your Garden

When it comes to optimizing your greenhouse setup, selecting the right plastic is crucial. The material you choose directly affects the growth, health, and yield of your plants. With so many options available, understanding the features and benefits of each type can help you make an informed decision.

Key Factors to Consider

  1. UV Protection
    Greenhouse plastics with UV stabilization shield plants from harmful ultraviolet rays while allowing beneficial sunlight to pass through. This not only protects your crops but also prolongs the life of the plastic.
  2. Light Diffusion
    Choose a plastic that offers adequate light diffusion to distribute sunlight evenly throughout your greenhouse. This reduces shadows and ensures consistent plant growth.
  3. Thickness and Durability
    Thicker plastics (measured in mils) offer greater durability and insulation. For regions prone to harsh weather, consider plastics that are at least 6 mils thick.
  4. Special Features
  • Anti-Drip Coating: Prevents water droplets from forming on the plastic, which can block light and cause fungal growth.
  • Infrared Retention: Helps retain heat during cold nights, keeping your greenhouse warm.

Recommendations Based on Needs

  • Home Gardeners: Opt for light-diffusing plastic with anti-drip properties.
  • Commercial Growers: Look for multi-layer films with UV protection and thermal insulation.
  • Cold Climates: Use IR-treated plastic to retain heat effectively.

Does my raised garden bed need to be covered all year round?

Not always. The type of plant, the season, and the weather all affect it.

Will garden coverings prevent my plants from receiving sunlight?

The majority of coverings, such as plastic or mesh, let enough light in. Shade cloths are designed to block off sunlight.

Can I cover my garden with old blankets or bed linens?

They work well for short term frost protection, but not for long term use.

How should I water my plants when they are covered?

Water directly via breathable coverings or with drip irrigation. For plastic, submerge in water for a short time.

Are there coverings made especially for gardening in the winter?

Yes, insulated plastic coverings and cold frames are ideal for winter crops.
