In case of more area, you can start in a pool or pond or larger tanks in your back yard (warmer climates).

Requirements to Grow Spirulina at Home:- Well, there are certain things you must build/gather before start growing Spirulina at home.

  1. You must have a tank with your preferable size. It can be cement or plastic.
  2. In order to harvest and squeeze the water out of thick Spriluna, you must have some kind of harvesting equipment like fine cloth and mesh.
  3. You may require Thermometer, air pump (for agitation), water pump for circulation, pH meter, Electric water heater, and any LED lights.
  4. Plain water may not be a good option for growing Spirulina, so you need to buy minerals for better growth of algal. This food or cultural medium is mandatory for growing this superfood.
  5. Plain filtered water plus Sodium bicarbonate plus Magnesium sulfate plus Potassium nitrade plus Citric acid plus Common salt plus Urea plus Calcium chloride plus Iron sulfate plus Ammonium sulfate make the perfect cultural medium.
  6. Spirulina thrives best in warm temperatures and ideal temperatures for its growth is between 25 and 38 degrees Celsius. Though this can tolerate low temperatures, it is always better to provide warm climatic conditions. You can use water heaters to increase the required temperature.
  7. You need Spirulina seeds to start your culture or you can buy Spirulina starter kit in any organic store. Spirulina starter kit contains the mother Spirulina culture (algae) in the bottle along with medium (water). You must make sure to buy from a certified store.
  8. Though it can be grown in any size of the tank, the preferable tank size is about 10 feet x 5 feet x 1.5 feet. Fill this tank with 1000 liters of water to a height of about 1 – 2 feet. This tank size requires about 1 kg of Spirulina mother culture. This Spirulina culture along with required minerals should be released into the tank. The minerals required for this scenario is 8 grams of sodium bicarbonate plus 5 grams of sodium chloride plus0.2 grams of urea plus 0.5 grams of potassium sulfate plus 0.16 grams of magnesium sulfate plus 0.052 ml of phosphoric acid plus 0.05 ml of ferrous sulfate. These measurements should be considered for 1 liter of water. After releasing the mother culture and minerals into the tank, the water should be agitated every day for 1 week using a long stick for 25 to 30 minutes.
  9. Drying racks needed in case of more production to dry the produce and preserve it.

Parameters to Consider Growing Spirulina at Home:- There are some things need to be considered for growing Spirulina at home.

Spirulina Stages.
Spirulina Stages.
  • Light: Growing area (tank/pool/basins) should have proper sunlight as Spirulina is like a plant and need light to survive.
  • Temperature: Requires temperature maintenance in tanks for maximum yield.
  • The agitation: Frequent agitation should be carried out to ensure all the Spirulina filaments have access to Co2 and light.
  • The Cultural Medium: Ensure to have the right culture medium and perfect water for better growth and high yield.

Harvest and Post-Harvesting in Spirulina Growing:- After 2 to 3 weeks, Spirulina will be ready to pick. Use any small and clean plastic buckets or a mesh to collect the algae and pour the algae into a mounted filter. This can squeeze/drain the excess water from harvested algae. Subsequently, the drained Spirulina should be wrapped in a clean muslin cloth. Press the drained material under a weight of 40 to 50 kg to further drain the moisture from material. Now you can put in like noodle manufacturing machines and squeeze in the form of noodles on a dry, clean cloth under the sun. Allow this to dry further for 2 to3 hours after which it should be ground in a machine (like a flour machine). The ground Spirulina powder should be sent to the lab for testing. Once everything is fine, then it should be packed in small airtight plastic covers and is ready for market and consumption.

Profit in Growing Spirulina:- With the tank dimensions mentioned in the above paragraph, you harvest 1 kg of Spirulina from each tank per day (if you have multiple tanks with the same dimensions).
