ABSTRACT:
A container for aeration of a substrate supporting a plant with the substrate being received in a cavity of the container so as to bury a device positioned in the cavity such that gas can be supplied from the device to the substrate. The device comprises a body having a peripheral wall defining an inner cavity. The peripheral wall has a portion permeable to gas such that a gas can flow therethrough from the inner cavity of the body to an exterior of the device. A gas permeability of the body decreases as a function of a vertical orientation of the body. The body has an inlet adapted to receive a gas to fill the inner cavity. The device is buried in a predetermined position with respect to the vertical orientation, such that greater amounts of gas can be supplied to the substrate relatively to a depth of the device.
