Suitable Conditions
Spirulina grows in solutions of specific minerals with the correct chemical balance and a pH of 8-11. There are various different recipes for this, depending on the budget available and the conditions. It needs a minimum of 20˚C to grow substantially, though a temperature of 35-37˚C is most effective. A good amount of sunlight is useful if the culture has a reasonable temperature and concentration. At very low temperature, low concentration of culture, or a culture that is struggling to grow.
