Arthi described the workforce and working hours in her own style-

"About 12 women are working on our production site. One lady can manage 3 tanks. Every day they will come at around 7 am in the morning and do the harvesting work. In each tank, it is about 4000L, exactly 3600L of culture is there in each tank. That is about 20cm in depth. Every day we can harvest, we can take out some of the quantity, that’s called harvesting."

"We are having a special cloth called mesh cloth. We use that cloth, 350µm or 400µm or 450µm, (that is up to the size of spirulina, we can change). Using the mesh cloth, we pour the culture through the filter, we can filter only spirulina and the remaining medium will go again mixing to the culture" -Arthi said.

The process of cultivation is simple but amazing, As she explained-
"Every day, we can harvest spirulina, about 1/4th quantity of the culture. In 3600L we are taking out 900L. From that 900L, whatever quantity it has, like 2kg, or 2,5kg, or 3kg of wet mass we can take it out."

She continued to say.
"It is like a green color thick duff like, so it’s called slurry. That slurry is again washed with pure water, filtered water because we are maintaining spirulina in a very alkaline medium so when it comes out it will have some other nutrients too, we have to wash it properly. Then, after washing, we will dry it in the food-grade polyethylene sheds. We spread it in a very thin way so that in photo pyrolysis, it will get well dry. We are doing harvesting in the early morning because we have to dry within a day."
