DETAILED DESCRIPTION - System comprises: an illumination means to control spatial, temporal and spectral characteristics of illumination surrounding a growth chamber, comprising an array of individually actuable light sources, made up of organic LEDs (OLED) which is a LED whose emissive electroluminescent layer is composed of a film of organic compounds that emit light when an electric current passes through it; a biomass detection means comprising at least one imaging device which can identify and map location and quantity of plants in a growth medium within the growth cell configuration; a plant stress detection means to acquire spatially distributed image data which characterize plant vigor and stress within the growth chamber, according to the growth tube cell patterns; an environmental monitoring means to monitor many environmental parameters that affect plant growth in a liquid within a growth chamber; environmental control means to control each of the parameters; and an expert system coupled to receive data generated by the biomass detecting means, plant stress detection means, imager and environmental monitoring means, and coupled to control the illumination means and the environmental control means. The layer of organic semiconductor material is formed between two electrodes, where at least one of the electrodes is transparent. As passive-matrix LCD versus active-matrix LCD, OLEDs can be categorized into passive-matrix and active-matrix displays. Active-matrix OLEDs (AMOLED) require a thin-film transistor backplane to switch the individual pixel on or off, and can make higher resolution and larger size displays possible. The individual pixels then can be turned on as a group to produce light in the visible spectrum and containing frequencies that are particular to maximizing the group of the biomass material through photosynthesis. The array surrounds the group tube containment vessel whether the tubes are vertical or horizontal configurations and supply lighting in the required frequencies needed to maximize plant growth and to minimize the power consumption of the system, which can be in tandem with other lighting support such as centered mercury and other prior art lighting for agricultural based systems. The system can also supply specific on and off spectral frequencies, a continuous rolling mode switching the spectral frequencies into a dynamic moving configuration. This control allows for specific control over the circadian day night rhythm to increase plant growth. The lighting system is arranged as a blanket around the growth tubes within the system and having differing spectral wavelengths, and means for individual control and modulation of the light sources within each growth tube of the system so that a series of growth tubes would create a cell of tubes either in a vertical or horizontal configuration. The plant stress detection means comprises at least one imaging device consisting of multispectral imagers, or hyperspectral imagers. The expert system contains a knowledge base that includes heuristic information, a plant database containing cultivation diagnostic and spectral information for plants growing within the growth chamber, and plant biomass and stress detection algorithms. The expert system is trained to regulate the illumination, environmental parameters and the motors pumps and valves that control movement of plant material, nutrients and gases within the growth tube chambers as many wholes. The expert system is trained so as to achieve optimized uniform plant growth with minimized consumption of energy and materials, to diagnose deviations from optimal growth conditions, and to determine and implement remedial actions by adjustment of the illumination, dissolved gases and environmental parameters. The expert control system would repeat indefinitely the expert control cycle to remove mature plants and materials from the environment to a predetermined process holding area and renew the expert process by bringing in startup plant growth materials and recycled and new nutrients and gases to repeat the process again until maturity is again retained and to repeat this process. The system contains growth modules which are defined as many grow tubes in cell, and multiples of these cells in the system. Each growth cell contains many growth tubes arranged in either a vertical or a horizontal configuration for all. Each cell with its growth module tubes has sensing control modules to monitor the biomass materials, gasses, nutrients, lighting, flow and maturity of the biomass. The biomass and the additional materials circulate within many cells until mature as defined by the expert control system. At maturity the biomass and all materials are taken to the extraction system which separates the algae fuel, also called algal fuel, algae oleum or second-generation biofuel. The expert system which controls this entire process is connected through a wireless mesh network (WMN) throughout the entire system which terminates at the expert system which is trained to operate the entire production process. INDEPENDENT CLAIMS are also included for:    (1) a system (A1) for achieving optimized plant growth; and    (2) a system (A2) for controlling crop growth within a growth area.
