Access the Tools and Information to grow Spirulina

What is Spirulina?

Spirulina is a helical shaped cyanobacterium that grows in warm, alkaline water. Under good conditions and adequate light it can double in biomass every 48 hours.

Spirulina has been historically used as a food source for the ancient Aztecs and inhabitants of Lake Chad in Africa. The cells contain high levels of iron, antioxidants, protein, and beta carotene. This algae has been taken to the International Space Station for testing suitability in environments with little resources.

With the right tools, you can grow this superfood at home with minimal space, time, and resources. At Orr Biologicals, we believe science should be open to everyone. Growing microalgae like spirulina is a hands‑on way to learn about biology, sustainability, and the future of food—all from a single bottle on your windowsill.

FAQs

What is spirulina?

Spirulina is a nutrient-rich blue-green algae often used as a superfood.

How do I start growing?

Begin with a small container, clean water, and spirulina culture to grow your first batch.

Phyconet is an experimental open‑source project. Results will vary depending on your algae strain, reactor setup, and local conditions. We make no guarantees of specific yields. The AI is a research tool, not a certified safety device. By supporting this campaign, you’re helping us test and improve a prototype that we believe will make algae cultivation easier for everyone.
