The present disclosure describes an apparatus for hydroponic plant production which comprises a plant production space and an irrigation system. The plant production space is enclosed by a plurality of surfaces. Columns of holes may be made through one or more surfaces. Holes of one column and holes of an adjacent column are arranged in a staggered manner. The apparatus may also include a cap and a supporting frame. The cap and the supporting frame are secured with the surfaces through fastening mechanism, which improves stableness of the apparatus.
