Humidity trays provide the extra moisture that many indoor plants and orchids thrive on. Just add water and let the slow evaporation do the rest. Removable grid for easy cleaning. Strong and durable plastic to withstand the weight of clay pots. Will not bend or twist when full of water.

The depth of the tray to the bottom of the grid is ~ 1 1/2". The top of the grid is ~ 1/4" below the edge of the tray.
