grow spirulina at home in 5 gallon water bottlesSpirulina (Arthrospira platensis) is a naturally occurring blue-green micro-algae which grows and thrives in warm water alkaline lakes. Wild grown spirulina sustains flamingos in the East African Rift Valley lakes and has the strength and ability to thrive in conditions where other algae cannot grow. It is a single celled organism that turns sunlight into micronutrient life energy. It is one of early life forms originating more than 3.6 billion years ago, and its spiral shape is what gives it the common name of spirulina.

Spirulina properties

Spirulina has amazing properties and in many ways can be considered a Super Food. It contains the most remarkable concentration of nutrients known in any food, plant, grain, or herb. It’s composed of 60% highly digestible vegetable protein. It has extremely high concentrations of beta carotene, vitamin B-12, iron and trace minerals, and the rare essential fatty acid GLA – Gamma-Linolenic Acid (which people who have not been breast fed do not have).

Spirulina has a balanced spectrum of amino acids, cleansing chlorophyll, and the blue pigment, phycocyanin, with high antioxidant properties. All the essential vitamins and minerals a body requires can be provided by spirulina, these provide a variety of benefits for the human body, like nourishment, mental clarity, assisting in cancer recovery, depression help and many others. Several scientific studies show spirulina to have the ability to inhibit viral replication; in particular it was found that 5-10 mg/ml of spirulina will inhibit the HIV-1 virus otherwise known as the AIDS virus. Its high protein and nutrient content make it an ideal food supplement and an immune booster.

10 benefits from taking 5-10 grams of spirulina every day:

  1. Increases the CD4 count – Strengthens the immune system (particularly useful for HIV/ AIDS eat spirulina to boost your immune systempatients.
  2. Increases RNA (Ribonucleic acid) in the brain for more energy
  3. The beta carotene (contains 10 times more that of carrots) is an excellent source of disease fighting antioxidants, and is also good for healthy eyes and vision.
  4. Contains vegetable protein and amino acids to build muscle
  5. High concentration of B Vitamins; which not only break down carbohydrate and lipids but also maintain cardiovascular health.
  6. It is also an excellent anti-inflammatory, which is an essential benefit to arthritis patients and prevents heart disease.
  7. Contains anti-aging properties.
  8. Improves digestive health
  9. Contains easy to absorb iron supplements ideal for women and children.
  10. Reduces cancer with antioxidant protection

What some Institutions and Organizations have said about spirulina:

  • The Immune System Miracle Worker (San Francisco Medical Research Foundation)
  • Worlds’ Most Powerful Food (
  • Spirulina is the most ideal food for mankind (United Nations Recommendation)
  • Spirulina: Food for the future (Publication by the USDA – United States Department of Agriculture).
  • “There is a need for both national governments and inter-governmental organizations to re-evaluate the potential of Spirulina to fulfil both their own food security needs as well as a tool for their overseas development emergency response efforts” – The UN-Food and Agriculture Organisation (FAO) Report on Spirulina 2008.
  • “For WHO, Spirulina represents an interesting food for multiple reasons, rich in iron and protein, and is able to be administered to children without any risk. We at WHO consider it a very suitable food.” – United Nations World Health Organization (WHO), Geneva, Switzerland June 8Th, 1993
  • Spirulina- was declared by the United Nations World Food Conference of 1974 as the best food for the future.

You can grow spirulina at home, it’s easy!

To grow spirulina at  home can be very rewarding and exciting. It’s an excellent activity to do with your kids and if you are dedicated to healthy living, it will save you money! Did you know that fresh spirulina is 3 times more potent than the dry form! And the taste, O.M.G., you owe it to yourself to try at least once fresh spirulina. No comparison!

The good news is: Grow spirulina at home is not harder than keeping a fish tank!
Of course it’s a super environmentally friendly way to produce and consume a complete protein too! Indeed, growing spirulina (at home or in a large farm) uses very little water and energy.  And the best of all: it canGrow spirulina at home in a small pond be grown indoor or outdoor, making it one of the most important things you can do to improve your health greatly!! This is why the NASA is using it and the FAO calls it the “food for the future”. You can start growing your own spirulina with only a small aquarium in front of a sunny window or if you have a large family, set up a little production pond at home in your yard!

There are a few elements that are important and that you need to consider before you start. The four
major components to successfully grow your own spirulina at home are:

What’s required to grow Spirulina at home?

  1. A tank or bassin, the size will depend of the quantity of spirulina you wish to harvest. A average size fish tank will be enough for a family of 4. For larger installation, in average, you can harvest 10-12 gr of dry spirulina per square meter of bassin.
  2. The culture medium, made of water + the “food” for spirulina (=Sodium bicarbonate (if direct CO2 is not available) • Magnesium sulfate • Potassium nitrade • Citric acid • Common salt • Urea • Calcium chloride • Iron sulfate • Ammonium sulfate)
  3. Harvesting equipment
  4. Spirulina seeds to start your culture
  5. Drying racks if you produce more fresh spirulina than you can eat and need to dry it to preserve it.

Important Parameters to Grow Spirulina at home

The first t is the light. Spirulina is like a plant and need light to survive (spirulina is actually a cyanobacteria but it need the light to realize photosynthesis). Visit this page for more information on how to provide the right amount of light to grow your spirulina culture at home.

Once you have the lighting figured out, the next step is to make sure you have the right temperature for your little cyanobacteria. Here again, nothing too complicated, spirulina will grow in a large range of temperature but there is a narrower range where it will yield the maximum production – it’s all explained here.

The next step to grow spirulina at home is to make sure that your tank or pond is correctly agitated / aerated so that all the spirulina filaments have access to light and CO2.

The final, and also one of the most important, step is to make sure you have the right culture medium and the right water for optimum growth. It can be quite daunting in the beginning but after a few tries, it gets much easier, and in no time you’ll be growing and eating fresh spirulina!
