When buying a receptacle, you don't need to choose a big one, which is bigger than the bottom of the flowerpot. Generally, you can put down the flowerpot without shaking, tilting or being too deep, because stagnant water will attract mosquitoes.
The tray has two functions. First, there is a hole in the middle of the bottom of the flowerpot, which is used for ventilation and water permeability to prevent the flower roots in the flowerpot from rotting and dying. This tray is used to catch the leakage of flowerpots. Twenty flowerpots are divided into two parts, a disc part and a wheel part. The disc part is made of high quality polypropylene by injection molding. The wheel is made of plastic injection molding. The use of this tray facilitates the movement of large flowers, effectively solving the shortcoming of inconvenient movement of ordinary trays.
