Abstract: A LED grow light array and method for controlling thereof, aimed at increasing plant canopy light penetration without stationary hot spots, providing antimicrobial light to eliminate microorganism on plants, providing pulsing canopy penetrating and microbial light without a dark period, and reducing energy consumption, the LED grow light array comprising: a LED grow light array, the array comprising at least four light bars, wherein the light bars comprise discrete photosynthetic LED chips of different types based on the wavelength of light they emit, the light they emit being either blue, red, or white light, or a combination thereof, wherein blue light wavelength ranges from 405 nm to 450 nm, red light wavelength ranges from 630 nm to 720 nm, and white light is a combination of wavelengths that ranges from 400 nm to 700 nm, each type of photosynthetic LED chip forming a set of chips; wherein the bars are in a series and spaced evenly over a given plant growing area; wherein the light bars further comprise d

Abstract: An improved ceramic discharge vertical lamp tower is designed for growing plants. A plurality of daisy chained ballast boxes are mounted between a pair of vertical frame members. Each ballast box powers a ceramic discharge lamp or any chosen alternative. Each ballast box may also power auxiliary LED lights. A controller can vary the cycle times of each augmented LED light panel and/or the ceramic discharge lamp. Various cooling heatsink designs include air and water.

Abstract: An improved ceramic discharge (hanging) lamp is designed for growing plants. A top mounted quick disconnect ballast provides maximum reflection area around the bulb. This also provides a quick disconnect for maintenance. Multiple ballasts can be daisy chained from one high voltage receptacle. An augmented LED or other light source can be attached to a lower frame or to the top frame to provide added light colors at various growth stages. A controller can vary the cycle times of each augmented light panel. The primary reflector maximizes the efficiency of the bulb.
