Abstract: A plant develop device includes a tubular structure, a water supply device, and a soil package. The tubular structure forms a plurality of growth holes, and a plurality of water conservation grooves are formed at a bottom of an internal surface of the tubular structure. Growth medium is wrapped by the soil package therein, and a through hole corresponding to one of the growth hole is formed on a surface of the soil package. The plant develop wall of the present invention includes the plant develop device, a rack, and a positioning ring which is used to fix the tubular structure on the rack. Thereby, the present invention can provides sufficient room for plant growing, improved fixation, and water regulation.

Abstract: A plant develop rack includes a base, plural soil packages, a water supply device, and a water collecting tank. Plural rack units are disposed on the base and are arranged vertically. Each soil package encloses growth medium and plant and forms plural openings for the plant to extend outward. The water supply device is located above the rack units. Thereby, when the water supply provides water to the most upper rack unit, water may enter the soil package on that rack unit to nourish the plant. Thereafter, excess water may flow downward via draining holes of the rack unit to reach lower rack units. Thus, the soil packages on all rack units can acquire sufficient water for growing the plant.
