Abstract: In a chamber for cultivating plant growth, a plurality of light fixtures are employed, each containing a high intensity discharge lamp. The bulb of the lamp serves as an inner transparent wall and a globe functions as an outer transparent wall. In the space between the bulb and globe water is caused to flow in order to remove unwanted radiation and heat generated by each lamp before the radiation is transmitted into the growth chamber.

Abstract: An installation for continuously growing plants which includes one or more growth chambers wherein alternate periods of lightness and darkness are provided, and the environmental conditions are controlled. The plants are individually supported, and transported through the growth chambers in such a manner as to require a minimum amount of handling. A diverging track system is provided in one of the growth chambers for handling the plants in a prescribed manner and guiding them through the chamber. As the plants are moved through such chamber, increased space is automatically provided for plant growth. The installation is well suited for growing plants hydroponically.
