Abstract: A tubular membrane plant growth unit is described. The unit includes a tubular pipe with an opening in its wall. A tubular porous member is situated inside of the pipe. The member and pipe are arranged to provide a space between them for a seed to be positioned so that the stem of the plant grows outwardly through the opening and the roots of the plant grow in the space between the member and pipe. The unit is useful for hydroponic growth of the plant.
