The growth of spirulina in extremely salty groundwater is impressive. Added to this: harvesting is very easy.
Spirulina is an alga and, like other algae, grows in water, in our case in extremely salty groundwater, which we bring to the surface via a pump.
After the basins are filled with water, the spirulina culture is added, as it were the seed that is placed in the soil.
From that moment on spirulina doubles constantly and pretty soon the pools look as green as in our photos.
To ensure optimum growth and that all algae are supplied with sufficient oxygen and light, the water in the pools must be mixed several times a day. The easiest way to do this in Turkana is with a broom.
The growth of spirulina is impressive! Pretty soon the concentration of spirulina rises to such an extent that the individual algae knot and float on the surface.
Harvesting is now ready! Very simply with sieves or cloths.
Then the algae are dried by solar energy in a solar cooker and then crushed. Packed in small bags, the spirulina is ready-to-eat.
For new spirulina to grow in your pelvis, all you have to do is wait. The remaining algae, which were not fished out of the basin, continue to double and after a short time you can harvest again.
