There is disclosed a dome and lighting apparatus for a mini greenhouse. In an aspect, the dome has one or more grooves or channels adapted to receive a lighting module. In an embodiment, the one or more channels are positioned laterally or longitudinally on the top surface of a dome, such that one or more lighting modules may be received thereon to evenly light the entirety of the mini greenhouse under the dome. A groove or channel may be suitably shaped to accommodate a lighting element. The groove or channel may further include shoulders on either side to accommodate a reflector for the lighting element, which may be suitably angled to direct the light downwardly into the mini greenhouse. By aligning respective grooves or channels of two domes placed side-by-side, a lighting module may be received over both domes within the aligned grooves or channels.
