    Abstract: A new hydroponic growing system that incorporates a non-woven soft-sided fabric container housed and/or supported within a plant reservoir container is proposed. The present invention includes a main reservoir that is in communication with multiple plant reservoir containers connected each other. The predetermined intervals are set and controlled by the controller at the main reservoir to fill and drain the plant reservoir containers. With an aid of use of a soft-sided fabric container made of fine mesh-like non-woven material, the present invention minimizes the medium from travelling with nutrients when the pump is activated to drain the bucket. In addition, the present invention includes aeration devices, such as an air tube, creating a vent which minimizes water resistance when draining the bucket. Variations on the type or material for the soft-sided fabric container, and various methods for supporting and suspending the soft-sided fabric containers can be considered.
