Spirulina is relatively easy to cultivate under the right conditions, but maintaining high quality can be challenging. It thrives in high-pH, mineral-rich water with consistent agitation and ample sunlight. However, farms must closely monitor for contamination—such as heavy metals, harmful bacteria, and cross-contamination with other algae. Maintaining an optimal pH level (between 9 and 11) and using controlled drying methods are essential to preserve its nutritional value. Scaling up production requires automation of processes like filtration, harvesting, drying, and packaging, making commercial farming significantly more complex than small-scale setups.
