A plant cultivation light source includes a plurality of light sources configured to be turned on or turned off depending on a selected plant and a growth stage of the selected plant, and a controller. The controller is operable to turn on the light sources during a light period such that the light sources are operable to emit a light having a spectrum with a plurality of peaks to the selected plant. The light period including a first period and a second period and the first period preceding or following the second period. The controller is operable to adjust the spectrum of the light to alternate the first period and the second period during the light period.

A method of providing light to plants. The method comprises providing a plurality of plants within a room, grouping each plant of the plurality of plants into one of a plurality of groups of plants based at least in part on a desired total light integral (“TLI”) for each of the plurality of plants and providing the corresponding desired TLI to each plant of the plurality of plants by sequentially providing light to each of the plurality of groups of plants during a time period. For each group of plants, each plant has a substantially similar photoperiod and a sum of the photosynthetic photon flux densities (“PPFDs”) of all plants in the group of plants is substantially similar.

An indoor gardening appliance includes a grow module rotatably mounted within a liner to at least partially define a first grow chamber and a second grow chamber. A climate control system includes an evaporator plenum housing an evaporator, a fan assembly for urging air through the evaporator plenum, recirculation ducts for independently circulating air through the first grow chamber and the second grow chamber, and ambient duct systems for independently circulating fresh ambient air through the first grow chamber and the second grow chamber. A system of dampers selectively opens or closes each respective recirculation duct and ambient duct system for independent climate control of the first grow chamber and the second grow chamber.

A grow light includes a plurality of cool white LEDs, a plurality of warm white LEDs, and a driver electrically coupled to the cool white LEDs and the warm white LEDs. An intensity level and spectral composition of the radiant energy emitted by the grow light may be tuned or configured by varying a ratio of the quantity of cool white LEDs to the quantity of warm white LEDs, by varying a spatial arrangement among the cool white LEDs and the warm white LEDs, or by varying a level of current provided to some or all of the cool white LEDs and the warm white LEDs.
