Give a microscopic vegetable the right conditions of sunshine and water, and you can home-farm what some say is the world’s most nutritious food: spirulina.
Spirulina is a microscopic,spiral-shaped micro-algae that grows in both sweet or salt-water bodies. It’s a complete source of protein, containing every essential amino acid to build healthy muscle and tissue. Some companies like Dupont are exploring ways to turn it into an alt protein, that tastes like fish.
Spirulina is also rich in essential fatty acids, which protect and promote cardiovascular and brain functions. Protein, vitamins, minerals, micro elements – the tiny green water weed seems to have everything. For those who’d like to know more, this study goes fully into the properties of this natural superfood.
In 1974, the United Nations world food conference announced that spirulina was the ideal food for underdeveloped nations struggling to feed millions of undernourished people. We have posted here about about the optimistic picture the UN Food and Agriculture Organization painted after investigating spirulina farms in Chad.
It was thought that spirulina could only grow in large bodies of water, such as lakes. People in Mexico and Sub Saharan Africa have done so, for centuries. And although in Kibbutz Ein Shemer’s greenhouse, Arab and Jewish teenagers are developing techniques to mass-farm the healthful algae, most people still have to buy dried spirulina compressed into tablets.
But a young Israeli has designed a grow-it-yourself kit that anyone with a sunny window can use to grow fresh, vibrant spirulina.
Tom Vered has unveiled the world’s first home growing spirulina machine. Spirulina thrives in both fresh and salt water and has been known to mankind for hundreds of years. It is believed to have given the Mayans superpowers.
In the last 40 years, it has been produced in large-scale factories around the globe as dried powder. But it’s better fresh. Vered’s machine is ground breaking not only because it now allows consumers to grow spirulina at home, but also because one can consume it in its healthiest form – fresh!
The new Spirulina home growing machine (which by 2022 seems like it never commercialized beyond renderings and prototype) contains 10 liters of fresh Spirulina and comes with a specially designed 20 ml glass. With the simple push of a button you get your daily amount of filtered and dense superfood – right in the comfort of you own home!

What made you decide to grow spirulina yourself?
I was influenced by the social protests in Israel two years ago, where people set up tents in parks. I wanted to live very simply for a while, get to know other ways to live. So I packed my tent and moved to the Adamama permaculture farm in the Negev.
Adamama has many innovative agricultural methods. One was growing spirulina, in small pools, for their own needs. After a few months, I had to go back to my university studies – it was my last year. My specialty is product design for the environment and special needs people.
When I left Adamama, I took a little spirulina with me and started doing online research, contacting growers around the world and asking for advice. I was looking for other industrial models. After a year of research, as my final university project, I developed a way of growing spirulina at home, in an aquarium.
How much spirulina does an adult or child need every day?
A daily teaspoon of fresh Spirulina a day is enough. Different people have different needs so some may need more, but, for most people, one teaspoon is enough. I’m vegan, that’s why it was important for me to find a vitamin supplement.
Vegans, vegetarians, and pregnant women can benefit from it. Obviously, you have to eat other foods too, not just depend on spirulina!
Is it a lot of work to grow spirulina?
Spirulina grows very quickly. If you harvest a teaspoon from your home-grown culture, it will have reproduced itself by the next day. With a 20-liter fish tank that you put in a window, it will supply 1-2 people. It’s a very small farm that supplies your super-food. Maintaining it takes only a few minutes every day.
Does growing spirulina at home require special equipment?
Besides the live spirulina, you do need nutrients to add to the water and a few small devices like a water pump and pH meter. An aquarium is ideal, but you can use a recycled mineral water tank. Below is a photo of two recycled mineral water tanks strapped to balcony railings of an apartment, acting as spirulina farms.
Vered gives talks on spirulina and how to grow it. Contact him through his website to learn more.
So how do you actually eat spirulina?
You can eat spirulina in a variety of ways: smoothies, salads, or spreads, or as an addition to cold drinks. Do not heat or cook the spirulina or it will lose some of its nutritious value. It is best eaten shortly after removing from water (up to half an hour). You can store it in the refrigerator for up to 24 hours or freeze it for several months.
