Far-red radiation and elevated CO₂ boost biomass accumulation in young leaf lettuce indoors

A new study from scientists at Purdue University reports that far-red radiation, in combination with increased carbon dioxide (CO₂) concentration, significantly enhances biomass production in young leaf lettuce grown under controlled environments, offering practical guidance for indoor farming operators enthusiastic about including far-red in their sole-source lighting recipes.
