Video transcript

While plastic greenhouses are economical, they have several disadvantages. Plastic degrades over time due to UV exposure, requiring frequent replacement. Temperature regulation can be challenging, as plastic traps heat, risking overheating in hot climates. Condensation buildup can lead to mold and mildew problems, affecting plant health.

Questions and answers

  1. Why does plastic degrade faster in greenhouses?

    Plastic materials in greenhouses degrade faster primarily due to prolonged exposure to ultraviolet (UV) rays from sunlight, which breaks down the plastic polymers over time.

  2. How can overheating be prevented in plastic greenhouses?

    Overheating can be managed by improving ventilation, using shading materials, or installing cooling systems to regulate temperature inside plastic greenhouses.

  3. What causes condensation buildup in plastic greenhouses?

    Condensation occurs when warm, moist air inside the greenhouse cools and moisture collects on surfaces, which can lead to mold and mildew if not properly ventilated.
