Two bags made of impermeable, flexible plastic sheeting are suspended one above the other to form a system for growing and watering plants. The lower bag is open at its top end and filled with plant soil in which plant roots grow. The lower bag also has perforations along its side through which plant foliage grows and an upper fixation means used to suspend the system from a mounting hook. Drainage holes are provided at the lower bag's lower end. The upper bag has fixation means that suspend it abov e the soil contained in the lower bag. A series of pinholes pierced through the lower e nd of the upper bag permit water that is rapidly poured into the top of the bag to slowly drip onto the plant soil contained in the lower bag. Means are also disclosed for retaining and recycling excess water back into the system. |
