This spirulina growth medium is an Indian modification of the Zarouk formula that is highly popular among commercial spirulina growers in India and the Far East. Not only does it simplify the preparation process, saving you the hassle of handling hazardous elements, it also has shown to yield more spirulina at lower production costs.

Is this Spirulina Cultivation Formula Organic?

Numerous Spirulina cultivation farms that use this formula have been certified as organic. The fact that spirulina thrives on inorganic matter makes the organic certification for spirulina a bit conspicuous. Although the mineral nutrients used in this formula are predominantly inorganic substances, they are widely used in the food industry, which makes them a lot safer to use than their chemical counterparts. At the bottom line, this formula offers good quality spirulina that can be certified as organic, depending on the standards of the certifying organization.

Why we created this manual

Spirulina can be quite sensitive to changes in the climate, quality of air, and nutrient compositions in the water. While different cultivation methods are available, most documentation on growing spirulina is written with scientific terminology that most people aren’t familiar with.

Our online calculators simplify the research process by focusing on what matters most: the numbers.

Whether you’re growing spirulina in a raceway pond, a photobioreactor, or an aquarium on your windowsill, knowing the exact nutrient proportions needed in your tank makes it easy to experiment with different growing methods and choose the one (or more) that work best for you.
