What is a trade-off of using plastic film as a greenhouse covering?

• A. Highest durability
• B. Low cost but shorter life and more maintenance
• C. Always lowest maintenance
• D. Best insulation

Answer: (B)

Choosing a greenhouse covering involves weighing upfront cost against durability and upkeep. Plastic film is very affordable and quick to install, which makes it attractive for low-budget or temporary setups. The trade-off is that this material doesn’t last as long as sturdier options and requires more ongoing attention. UV exposure, weather, and handling can cause the film to become brittle, yellow, or tear, reducing light transmission and structural integrity over time. Because it wears out sooner, you’ll likely need to patch, re-tension, or fully replace the film after short intervals, adding maintenance labor and recurring material costs. In contrast, more durable coverings like glass or polycarbonate cost more upfront but tend to provide longer life and better long-term performance, including insulation, so the overall operating costs can be lower over time. This is why the option describing low initial cost with shorter life and more maintenance best captures the trade-off.
