A method and apparatus for metabolism manipulation of life forms using spectral output which comprises at least one array of LED light sources which have metabolic manipulating spectral emissions. The array sends one or more environmental signals selected from the group consisting of day/night cycles, seasonal cycles, competitive signals and harsh condition preparedness. A remotely programmable microcontroller is operatively connected to the at least one array for controlling the spectral emissions in a desired manner. The microcontroller selectively sending on commands, off commands and intensity commands to the at least one array. The method and apparatus include software for driving the microcontroller and the software is stored in a memory. A power source is operatively connected to the at least one array of LED light sources, and a graphic user interface facilitates inputting information, by an operator.
