In our work we tried to grow spirulina in a different climate from the original climate and monitor the natural evolution over a week, taking into account the climatic factors and physical chemicals that affect its growth. From obtaining biomass worth 1.9 grams in a liter and a half. Finally, we conclude that spirulina has the ability to grow despite different climatic factors if it is provided with the appropriate agricultural medium.frSpirulina, culture, different climate, growth, biomass.Spiruline, culture, climat différent, croissance,biomasse.
