Abstract: The extant invention is a portable and modular plant growing system comprising at least one plant growing container, each container having a longitudinally elongated vertical enclosure with at least one perforated platform to support a plant growing medium, and at least one opening proximate to the bottom of the container. The enclosures also have holes to permit water drainage and air circulation. A system is provided for conveniently and economically interconnecting the plant growing containers. This interconnecting system comprises modular, snap together commercially available spacers that cooperatively receive and connect together adjacent plant growing containers.
