Plant metabolism and growth are reduced in low temperature. As metabolism slows, energy requirements are reduced and less light is needed. The temperature should be maintained above the chilling temperature for the plant, which is species dependent. The addition of light will allow the plant to continue to expend energy on maintenance and some growth. Here we show that low light and cool temperatures can be used to maintain plants through the 14.7 days on the dark side of the Moon. Growth resumes immediately after the light is restored.
