You can find the plant in a warm lake where the pH is above 7, but you can also find it to harvest in saltwater and hot springs. It can again thrive well in alkaline solutions, which wouldn’t ordinarily be unfavorable for many other plants. Growing it outside its natural habitat will require water with a pH of between 8 and 10. Before I share with you suggestions on how to grow the plant, let’s first talk about some of the ways you can benefit from spirulina.

How to Grow Spirulina At Home
First, you should know that spirulina is a water plant, meaning you won’t need to cultivate it on land. You will need a container or pool which can be sited in your yard or roof depending on where there is available space.
What You Need For Spirulina Cultivation
To get started, you want to make provision for a grow chamber. This could be a glass container or an aquarium tank. Others include:
- Fresh spirulina
- Containers (preferably aquarium)
- Litmus Paper
- Filtration cloth
- Agitation device
Prepare Culture Medium For Growing Spirulina
You will have to prepare for the culture medium. This will house the nutrient bed from which the plant gets its nourishment. To prepare a culture medium, you want to
- Mix the water and fertilizers depending on the quantity you will use in your container. This means that for 20 liters of spirulina, you want to make available 20 liters of culture medium.
- The fertilizer has to dissolve completely in the water before adding in the spirulina. This can take a while, so I recommend agitation to speed up the process. You can do this with a pump or stick to prevent the plant from gathering on the water.
- The best temperature to encourage growth for spirulina is 30-35c.
- You should keep the pH between 10 and 11, but you can get positive results from 8 onwards, but most growers keep it slightly high alkaline. Too low, and it risks being contaminated, and also high, it can change chemically, which will affect the result.
- The salinity of the mix is also something to take note of. You can make use of a refractometer to keep the salinity between 15 and 20PPT.
- When the medium is ready, you can add fresh spirulina.

The best time to harvest your spirulina is in the morning, where it would be less stressful to do, plus you can be sure of the nutrient content. To harvest, hold a filtration cloth over the container and pour out the culture on the fabric. You will then collect the spirulina inside the cloth while the culture medium will flow back into the container.
You want to enjoy your spirulina after harvesting as it best when fresh. It could also stay in the refrigerator for three weeks after preparation.
