What are the differences in material stretch between polyester and canvas outdoor planters when wet?

When choosing outdoor planters, understanding how materials behave when wet is crucial for durability and performance. Polyester and canvas are two popular options, but their stretch properties differ significantly in wet conditions.

Polyester planters are made from synthetic fibers that resist stretching when wet. The material retains its shape well, even after prolonged exposure to moisture, making it ideal for humid or rainy climates. Polyester's low absorbency prevents excessive sagging or deformation, ensuring long-term stability.

Canvas planters, on the other hand, are typically made from natural cotton or blended fibers. When wet, canvas tends to stretch more due to its absorbent nature. This can lead to slight sagging or loosening of the fabric, though high-quality canvas may include water-resistant treatments to minimize stretching.

In summary, polyester planters offer better shape retention in wet conditions, while canvas planters may stretch more but provide a more natural aesthetic. Your choice depends on climate, aesthetic preferences, and desired maintenance levels.
