What are the differences in thermal conductivity between fabric and canvas outdoor planters?

When choosing outdoor planters, understanding the thermal conductivity of materials like fabric and canvas is crucial for plant health. Fabric planters, typically made from breathable materials like geotextile, have lower thermal conductivity, allowing them to insulate roots from extreme temperatures. This helps maintain a stable root environment, preventing overheating in summer and freezing in winter. Canvas planters, on the other hand, often have slightly higher thermal conductivity due to their denser weave, which can transfer heat more efficiently. While canvas offers durability, it may not provide the same level of temperature regulation as fabric. For gardeners in climates with temperature extremes, fabric planters are often the better choice for optimal heat retention and root protection. Both materials have their advantages, but fabric generally outperforms canvas in thermal insulation.
