A vertical hydroponic plant production apparatus for allowing vertical hydroponic greenhouse crop production is provided. The apparatus comprises a hollow grow tube having a front face, a back face, an open first end, and an open second end. A slot is formed in the front face of the grow tube with the slot having a width equal to only a portion of a width of the front face. A media material is insertable into the grow tube. The slot allows the front face to expand outward during insertion of the media material and biased inward against the media material once the media material is inserted. The grow tube is positionable in either a horizontal position, vertical position, or any position between the horizontal position and the vertical position allowing inclined, multi-angled crop production and multi-storied conveyor style crop production.
