This invention provides a cost-effective means for both indoor and greenhouse farmers to use a Modular Light Emitting Diode (LED) Grow Light System to optimize light distribution and integrate natural light. The Modular LED Grow Light System consists primarily of multiple narrow “Linear Modules” connected to two “End Housings” with structure from “Support Braces” that together form each “Grow Rack” within the system. The Linear Modules are longer than their diameter, and the spacing between the Linear Modules is greater than their diameter. This creates spaces between each Linear Module with three primary advantages: more even light distribution, more integration of natural light, and more air flow for natural ventilation.
