Best Answer: yes, plants use oxygen at night... However, plants can't produce glucose, carbohydrates and oxygen without light. To get through the night, most plants reverse the process of photosynthesis and breathe, like you and I, by burning carbohydrates and oxygen while producing carbon dioxide and water.
Vegetable seedlings need 14-18 hours of light a day. Botanists usually divide plants into three categories relating to their preferred day length: short-day, long-day or day-neutral. Short-day plants, such as chrysanthemums, kalanchoe, azaleas and begonias, will thrive on less than 12 hours of light per day. In fact, these plants must usually go through a series of even shorter days before they will set buds and flower. Long-day plants require at least 14 to 18 hours of light each day.
