A simplified diagram of Design 1. Here 20 Norlux HEX arrays are configured into four individual banks of five arrays each. R, G and B are individually controllable on each bank, allowing the use of the controller to regulate light conditions over four independent light quality and quantity conditions. The four banks are regulated by two independent power supplies, actuated by two separate timers. In this configuration two separate photoperiods may be tested for any set of experimental parameters.
