What are the effects of high humidity on PVC outdoor flower pot structural integrity?
High humidity can significantly impact the structural integrity of PVC outdoor flower pots over time. Prolonged exposure to moisture causes PVC to absorb water, leading to material expansion and eventual warping. This weakens the pot's shape, making it prone to cracking or breaking under stress. Additionally, humidity accelerates UV degradation in PVC, reducing its durability. Mold and mildew growth in damp conditions further deteriorate the surface. To mitigate damage, choose UV-stabilized PVC pots, ensure proper drainage, and store them in dry conditions during extreme weather. Regular cleaning and protective coatings can also extend their lifespan in humid climates.
