Plants cannot get too much light, but they can get too much of the heat energy that comes with the light. Photosynthesis and other plant growth processes will shut down when the environmental and tissue temperature gets high enough that all the water taken up by the plant is used to cool the plant tissue.Do buds grow at night?
During the day, they use sunlight and CO2 to make sugars, which the plants store and use for growth.
