ABSTRACT:
A method and structure for improved natural lighting for plant growth, particularly for mass production of horticultural crops in environmental conditions where normal solar lighting may be inadequate for horticultural production within a greenhouse structure. The structure comprises a translucent shell on a base, the shell and base enclosing a predetermined space within which plants are to be grown. A reflective surface is situated adjacent major portions of the base, outside the shell and preferably below the level of the base, to reflect solar radiation into the space through the shell. The structure may also be provided with other features tending to increase the exposure of solar radiation to the plants.
