How to Maintain Woven Greenhouse Plastic for Long-Lasting Hydroponic Growth

 

A greenhouse is important in hydroponic gardening since it creates an environment that is suitable for the growth of plants. Of all the components, woven greenhouse plastic is the most durable and resistant to UV radiation, which is perfect for creating the necessary conditions. But to make it long-lasting and efficient, it requires constant maintenance. In this article, we will explain why it is crucial to keep the woven greenhouse plastic and how you can do it to make your hydroponic gardening continue to thrive.

What is Woven Greenhouse Plastic?

Woven greenhouse plastic is a type of polyethylene fabric that is used in the construction of greenhouses for various purposes. Unlike regular plastic, this material is woven which makes it to be strong and hard-hitting and cannot be easily torn or damaged. It is mainly applied on greenhouses to shield plants from extreme weather conditions while at the same time admitting light which is important in the process of photosynthesis.

There are different types of woven greenhouse plastic including the UV-stabilized types that can minimize the effects of the greenhouse on the plastic material. In the case of hydroponics, this plastic is advantageous because it regulates the temperature and humidity inside the greenhouse to favor the plants.

Steps to Maintain Woven Greenhouse Plastic

Here are the key steps to maintain woven greenhouse plastic for optimal performance and longevity in hydroponic growth.

1. Regular Cleaning for Better Light Penetration

One of the most common problems with woven greenhouse plastic is the buildup of dirt, dust, and other debris, which can block sunlight and reduce the effectiveness of your greenhouse. Over time, this accumulation can diminish the amount of light that reaches your plants, negatively impacting their growth.

How to Clean:

• Wash with Water: For routine cleaning, use a soft cloth or sponge and mild soap mixed with water to wipe down the surface of the plastic. This will help remove any dirt or dust without damaging the material.

• Pressure Washing: If the plastic has accumulated stubborn dirt, using a pressure washer can be a quick and efficient solution. Be sure to set the pressure to a low setting to avoid damaging the woven plastic.

• Avoid Harsh Chemicals: Always avoid using harsh cleaning agents or bleach, as these can weaken the material over time and cause premature aging.

2. Inspect for Tears and Holes

Woven greenhouse plastic is quite robust, but it can still tear or develop holes at some point, especially if it is located in an area that is prone to strong winds, heavy rainfall, or sharp objects. A small hole can let pests and weather elements into the greenhouse, thus disrupting the climate that you have tried to maintain.

How to Inspect:

• Visual Inspection: Take a round of the greenhouse and check for any signs of tear or any puncture on the plastic. This is because some areas are more susceptible to the formation of rust and this includes the edges, corners, and the areas that are in contact with the metal frames.

• Look for thin or worn areas: If you see any area that is thinner or more worn than the other parts of the plastic, it is advisable to strengthen them before they become problematic.

How to Fix:

• Tape and Patches: Small tears and holes can be repaired using clear plastic patches or greenhouse repair tape. It is also important to clean the area around the tear before applying any repair materials to avoid any slippage.

• Repairing Damages: In cases where the tear is big or the section has been badly damaged, it may be necessary to replace the plastic. If it is not possible to replace the whole sheet, one can opt to replace only the damaged part to cut costs.

3. Ensure Proper Tension and Support

Proper installation is key to the longevity of your woven greenhouse plastic. Over time, the plastic may sag or loosen due to environmental factors like temperature fluctuations and wind. If the plastic isn’t properly tensioned, it can stretch, leading to damage or reduced light penetration.

How to Maintain Tension:

• Regularly Tighten the Plastic: Check that the plastic remains taut and properly attached to the greenhouse frame. If necessary, tighten the ropes or fasteners used to secure it.

• Use Support Cables: Adding additional support cables can help keep the plastic under tension and prevent it from sagging. These cables can be installed along the roof and walls of the greenhouse to ensure an even distribution of pressure.

• Adjust Seasonally: Depending on the weather conditions and temperature fluctuations, the tension of the plastic may need to be adjusted from season to season to maintain optimal conditions.

4. Prevent UV Damage

While most woven greenhouse plastics come with UV protection, prolonged exposure to direct sunlight can cause the plastic to degrade over time. UV rays can weaken the material, leading to brittleness, cracks, and loss of effectiveness.

How to Protect Against UV Damage:

• Shade Cloths: During peak sun hours, use shade cloths or netting to reduce the amount of direct sunlight hitting the plastic. This will protect it from excessive UV exposure, prolonging its life.

• UV-Resistant Plastic: Ensure that the woven plastic you’re using is UV-resistant. While many varieties come with this feature, it’s a good idea to double-check that the product is designed to withstand prolonged exposure to the sun.

• Install Overhangs: Installing roof overhangs or additional shading structures around your greenhouse can help reduce UV damage to the plastic, especially in areas with intense sunlight.

5. Control Moisture and Condensation

Condensation can build up inside a greenhouse, especially during the early morning or late evening when temperatures fluctuate. Excess moisture can damage the woven plastic by promoting mold growth, which can weaken the material over time. Additionally, moisture on the plastic surface can reduce light penetration.

How to Manage Moisture:

• Ventilation: Proper ventilation is essential for reducing humidity and preventing condensation inside the greenhouse. Ensure your greenhouse has adequate vents and fans to maintain airflow and regulate temperature.

• Dehumidifiers: In areas with high humidity, consider using dehumidifiers to maintain an ideal moisture level inside the greenhouse. This will help prevent excess moisture from accumulating on the plastic.

• Waterproofing: Ensure that your greenhouse is properly waterproofed to avoid rainwater pooling on the plastic, which could potentially lead to mold and algae growth.

6. Replace Plastic Every Few Years

Despite all your efforts to maintain it, woven greenhouse plastic will eventually wear out due to constant exposure to the elements. Depending on the quality of the material and how well it has been maintained, you may need to replace it every 5 to 7 years.

Signs It's Time to Replace:

• Significant fading or discoloration

• Large areas of brittleness or cracks

• Reduced light transmission

Replacing the plastic before it becomes too damaged will ensure that your hydroponic plants continue to thrive in optimal conditions.

Proper maintenance of woven greenhouse plastic is essential for ensuring long-lasting durability and optimal conditions for hydroponic growth. By following key maintenance practices, you can protect your investment and support healthy, thriving plants.
