WebT h e superficial conclusion would be that if the visible irradiance is about 50 per cent of that in the open, then a supplement of infra-red increases the weights of the seedlings, the increase being proportional to the intensity of the added infra-red. (Note that the irradiation is measured as the heat content, not as the flux of photons.)
