Spirulina is a super food that anyone who knows the true value of organic food should eat. It is the best source of plant protein as it contains all the amino acids needed by the body. It is a complete protein and has many benefits to offer to the body when taken even in small amounts. A little spirulina a day will leave you fiddle fit. How can you benefit from this crop? You can buy but to reap even more benefits the best option is to grow your own spirulina at home. Wondering how to grow spirulina? We explain to you how you can go about it.
What will be required?
There are some basic equipment that anyone looking to grow spirulina needs to have. The first is the tank or basin whose size will depend on the amount of spirulina you wish to grow. Generally, you can grow a family of four in an average fish tank. The harvest is usually 10-12 g dry spirulina per square meter.
The culture medium on which the spirulina will grow is also needed. This is the water and food that the spirulina will feed off. You can buy the food premixed or mix sodium bicarbonate, ammonium phosphate, potassium nitrate and sea salt. The prior is the better option though. You will also need spirulina seeds to get started. You will also need ph strips to monitor the ph of the water from time to time, an air line or bubble wand for aeration and a heater and thermometer for the temperatures. For harvesting you will need a food grade harvesting tube and a harvesting cloth.
Meet the required conditions for growth
Spirulina undergoes photosynthesis and will therefore require light. So, place the tank in a place that has adequate lighting. This could be near a window inside the house or anywhere outdoors. Place the bubble wand along the wall of the tank and place the suction cup (part of the harvesting tube) to the tank’s wall. Mix 2.5 gallons of non-chlorinated water with one cup of the food’ mixture. Set the heater to 90 degrees F which is the optimal temperature for growth of spirulina. To make the water alkaline, add 16grams of sodium carbonate per liter. You can now add the spirulina and watch it grow. Mark the initial water level and keep adding water to replace what evaporates so the level is maintained. Be sure to cover the tank with a plastic or glass cover to reduce evaporation, contamination and preserve heat. To avoid iron deficiency issues, add chelated iron. The spirulina is now ready to grow. Leave it and it will begin populating within no time.
Within a month, you will see an increase in the spirulina population. You can now add more spirulina and water into the tank. Remember to keep adding the nutrients often.
You know it is time to harvest spirulina when there is a lot of it and the pH is 10 or above. This way you can be sure that what you get is safe for consumption with no contamination.
To harvest, open the valve leading to the harvesting tube and connect a harvesting cloth to the end of the tube. This cloth will catch the spirulina while the clear medium flows back to the tank. Only harvest a third of the spirulina so you can leave the rest populating fast. This way you will be able to harvest often.
