FAQ About Indoor Plant Lighting for Aquatic Systems
What is PAR in relation to aquarium lighting?
PAR (Photosynthetically Active Radiation) is a measure of the usable light spectrum (400 to 700 nanometers) that aquatic plants use for photosynthesis. It's an important consideration when selecting lighting as it indicates whether a light source can effectively support plant growth. PAR meters can be used to measure this in your aquatic system.
