Can you change light's wavelength by passing through a color lens? We are working with some plant species that do better under red and blue wavelengths.(no not the green sticky icky kind) ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Is placing a red or blue lens between the light source and the object the same as having a red or blue light(LED)?
