Abstract: In some implementations, an indoor grow system for plants includes at least a plant substrate system; a luminaire positioned adjacent to the plant substrate system, the luminaire includes a plurality of grow light panels, a lighting frame, and at least one luminaire connector, the lighting frame includes a plurality of frame members, the at least one luminaire connector is coupled between one frame member and another frame member adjacent to the one frame member, the luminaire connector adjusts the spatial position of the plurality of frame members that define the lighting frame and shape of the luminaire; and a plant canopy zone, defined between the plant substrate system and the luminaire rendered in a curvilinear configuration, and whereby the plant canopy zone defines a curvilinear space for illuminating the plants.
