patent number 6581327
A plant propagation apparatus is disclosed which comprises a flexible transparent enclosure. The enclosure is disposable, and could be formed of a polymer such as polyethylene. The enclosure would have at least two walls, formed of flexible material that facilitates transmission of light through the walls. Plant material is sealed within the enclosure, and nutrient solution is made available within the sealed enclosure for the plant. The enclosure is a low cost and effective method for propagating young plants and transporting them between the laboratory environment and a greenhouse or field. The enclosure may be configured to receive gas or carbon dioxide on its inner surface to a predetermined level of pressure, thereby affording the enclosure a flexible but stiff mechanical resistance that protects the young plant while it is growing.
