What are the differences in thermal capacitance between WPC and phase-change material flower boxes?

When comparing WPC (Wood-Plastic Composite) and phase-change material flower boxes, thermal capacitance is a critical factor for plant health and temperature regulation. WPC flower boxes, made from a blend of wood fibers and plastic, have moderate thermal capacitance, providing some insulation but limited heat retention. In contrast, phase-change materials (PCMs) are designed to absorb and release heat efficiently, offering superior thermal regulation by maintaining stable temperatures over longer periods.

The primary difference lies in their heat storage capacity: PCMs can store significantly more thermal energy due to their latent heat properties, while WPC relies on its inherent material conductivity. This makes PCM flower boxes ideal for environments with extreme temperature fluctuations, whereas WPC is better suited for milder climates. Understanding these differences helps gardeners choose the right material for optimal plant growth and energy efficiency.
