ABSTRACT:
A plant growth accelerating apparatus for increasing plant yields by effectively removing the growing plants from the constraints of gravity and increasing the plant yield per unit of space when the light intensity incident on the apparatus varies, and including a plant bed mounted for turning about the longitudinal axis thereof and a drive structure for periodically tilting the longitudinal axis of the plant bed while relatively low light intensities are incident thereon to impart thereto a slope from about 0.01 to about 0.25 to decrease the respiration rate of plants growing on the plant bed; there also is disclosed a structure applying the tilting structure to a multiple plant bed machine, as well as gravitational watering structure for multiple plant beds while turning the same, and improved plant bed structures and novel forms and compositions of rooting media and methods of making the same.
