Growing systems including double-walled growing devices, and methods of making and using the same are provided. Growing devices include two sheets of material, a sprouting layer and a rooting layer, strategically bonded together to form containers for growing plants. Each container includes openings in the layers to allow the plants to grow out of their containers and to allow roots to access water through the rooting layer. The two layers can be formed into a cylinder where the center of the cylinder provides a channel for watering such that the roots grow into that channel. Deployed as a flat sheet of containers, the device can include a third layer to provide a water channel between the rooting layer and the third layer. Growing systems include the device and can also include a system to provide water thereto, and an enclosure around the device for providing an overpressure.

A modular commercial plant cloning system and method for stimulating root growth from a plant stem. The system includes a supporting frame, a light source, a fluid reservoir, and a cooling element. The supporting frame further includes a plurality of mounting points for securing a plant holding device tray at a desired height and spacing within the supporting frame below the light source. The plant holding device tray houses a plurality of plant holding devices that the plant stems are placed in during the cloning process. The lower end of the supporting frame includes the fluid reservoir, wherein the fluid reservoir further includes a cooling element therein. Additionally, the fluid delivery system helps transport fluid from the fluid reservoir to the sprayer nozzles which are configured to distribute fluid across the plant stems disposed within the plant holding device tray.

A plant propagation system is provided that includes a holder for holding at least two plants in relative spaced apart relation to enable a predetermined operation (such as, for example, a cutting operation) to be performed on each of the plants within the holder during a single pass.

A hybrid plant growing system that supports aeroponic and hydroponic/deep-water cultures is based upon an elongated growing table configured to receive a plurality of reconfigurable panels with openings for cuttings, clones, or larger plants in net cups or pots. A spray manifold includes a plurality of spray heads under sufficient pressure to mist the root portions of the growing plants. Removable and replaceable baffle plates enable the system to support aeroponic plant culture with the baffle plates in position, as well as a hydroponic or deep-water plant culture, wherein the roots of the plants are allowed or encouraged to invade into the nutrient solution. End-wall ports enable a plurality of the tables to be serially cascaded and share a common reservoir. At least two sizes are provided, including longer tables having a length of about 8 feet, and shorter tables having a length of about 4 feet.
