Do Plants Produce CO2 at Night? Bedroom Plant Safety Debate

Are Bedroom Plants Safe? The CO2 Nighttime Controversy

Sean read that plants emit CO2 at night and wonders if sleeping in a plant-filled room is safe. He cites several sources, including NASA studies.

Expert Perspectives

Darlene's view: NASA found plants absorb CO2, release O2, and clean air if not overwatered (which causes mold). She keeps plants in her bedroom and believes they help combat global warming.

Follow-up: New research suggests high atmospheric CO2 and heat may alter plant respiration. Darlene finds sources confusing and won't move her plants until scientists issue clear warnings. She still believes plants are part of the climate solution.
