Systems and methods herein improve plant growth through a combination of monochromatic laser light and Emerson effect enhancement. A microcontroller can change the frequency of a laser module and an LED array to enhance growth. For example, 663 nm can be used as an energy pump, and a phytochrome effect can be applied at 730 nm during flowering to extend the amount of time a flowering plant can handle light. A racking system can accept slidable LED lights for easy positioning. Additionally, a controller can use one or more scalar wave guides for channeling scalar energy. These can be active or passive. In one example, a controller causes the scalar wave guide to create an electromagnetic cancelation field whereby the device harnesses the fundamental earth Shuman resonance of 7.83 Hz and amplifies it to create anions in a predominantly cation rich environment.
