Several factors are important for microalgae like temperature, light etc. Does relative humidity (RH) of air have any effect on growth/production of microalgae?
Microalgae colonize various habitats. For those living in the aquatic environment, RH cannot be a key factor per se . For other occurring in terrestrial habitats, this factor may control growth (eg. growth on rocks, barks, in the desert,..). Greetings Michael
