A grow light support system for use with a raised border system includes components for forming a tension cord network that is suspended over the raised bed border system and includes a grow light unit that is suspended on the tension cord network. The grow light unit is configured such that the grow light can be positioned and locked in place at a predetermined location of the tension cord network and is configured such that the distance between the grow light and the tension cord network can be varied, thereby changing the height at which the grow light is positioned relative to the ground.
