Why does pebble tray create humidity?

As the water evaporates from your pebble tray, it will create a bubble of humidity around the plant. Just top it back up when the water is almost gone and watch your plant thrive!

A pebble tray creates humidity through the process of evaporation. When water is added to the tray and the surrounding air comes into contact with it, the water molecules begin to transition from a liquid state to a gaseous state, forming water vapor. This water vapor increases the moisture content in the immediate vicinity, resulting in elevated humidity levels.

The layer of pebbles or stones in the tray serves a crucial role in the process. As the water evaporates, it first saturates the pebbles, and then the surrounding air interacts with the moist pebble surface. This interaction accelerates the evaporation process, releasing more moisture into the air.

The increased humidity is beneficial for indoor plants that thrive in higher humidity environments. It helps to mimic the conditions found in their native habitats, where humidity levels are typically higher than what is commonly found in indoor spaces. 

The elevated humidity provided by the pebble tray promotes healthier plant growth, prevents issues like dryness and leaf browning, and creates a more favorable microclimate for the plants to thrive.
