An illustrative embodiment of an irrigation system may include a carriage that may move along a predetermined path in a reciprocal manner. The carriage may support one or more exit ports that may be fed nutrient supply by a pressurized delivery arrangement. One or more plant stands may be configured and arranged to straddle the carriage as it moves along the predetermined path. The one or more plant stands may form a chamber into which plant roots may extend, and into which the one or more exit ports may discharge their nutrient supply. The one or more plant stands may include side panels and a cap to reduce infiltration of light and contaminants and to enhance the plant root/nutrient supply interface and absorption rates. The carriage and/or the plant stand(s) may include friction reducing elements that facilitate transverse movement. The carriage and/or the plant stand(s) may be supported by framework.

A method of growing a plant or its propagule is described. The method includes: (i) powering a light source with input power to generate an incident light; (ii) illuminating, for a period of time, a growth area of the plant/propagule with the incident light having a spectral profile defined by a first ( i.e ., between about 400nm and about 470nm), a second ( i.e ., between about 526nm and about 570nm) and a third ( i.e ., between about 626nm and about 700nm) set of wavelengths; (iii) achieving, using the incident light, a dry weight that is greater than that achieved if the growth area of the plant/propagule had been illuminated by another incident light with same amount of input power for substantially same period of time, and another incident light includes the first and the third set of wavelengths, but not the second set of wavelengths.

The present invention is related to an illumination armature (1) whose spectral structure can be controlled according to the needs of the plant and which can be used as lighting for growing plants in forced agricultural applications. The present invention describes a design of a plant growth armature (1) whose spectral structure and intensity can be controlled and which is strengthened at the wavelengths wherein the chlorophyll absorbance is high. The hardware, has been produced from a plurality of LED light sources (3) that have been combined to emit high radiance in wavelengths at which especially chlorophyll a and chlorophyll b show high absorbance. Energy efficiency is obtained by emitting the light in wavelengths that the plant can use instead of wavelengths that the plant cannot use directly to carry out photosynthesis.

An illumination device (1) for producing an illuminating light beam (7) to activate a photosensitive biological process comprises a light source element (2) configured to emit light at a wavelength range overlapping with the absorption wavelength band of the photosensitive biological process. According to the present invention, the light source element comprises a plurality of laser diodes(2) configured to emit primary light beams(3)at different wavelengths; and the illumination device (1) further comprises at least one diffusor surface (6a, 6b) configured and placed to diffusively redistribute the energy of the primary light beams(3) into the illuminating light beam (7) so that the energy density of the illuminating light beam leaving the illuminating device does not exceed the maximum permissible exposure of a human eye.
