Various embodiments of vertical hydroponic horticulture systems are provided that maximize space saving features and provide improved convenience and recyclability. The hydroponic systems disclosed herein use a simple flexible mesh tube that can be tied at the bottom, and optionally tied at the top, and filed with a suitable growing medium for hydroponic agriculture. A plurality of perforations is provided in the mesh envelope for plants to grow on the exterior of the envelope with their roots in the medium inside the mesh envelope. An irrigation water drip may be provided at the top of the tubular flexible mesh tube, and a water collector may be provided at the bottom of the mesh tube, and a pump may be provided for recirculating the aqueous nutrient solution from the bottom of the mesh tube to the irrigation water drip at the top. In an embodiment, the mesh tube may be hung from an overhead supporting member. In an embodiment, the entire system may be self supporting by the use of a rigid pipe that acts as
