a Spirulina cultivation kit.


Spirubrew is a kit for making a Spirulina growing system that provides the optimal environment for raising Spirulina for food in an indoor environment. It includes live Spirulina culture, growth medium starter mix, and essential nutrients. Users have an option of upgrading their kit to include an Arduino board and various digital sensors for making a digital data tracking system.

Spirulina farming poses an opportunity of introducing a new form of food and a new way of urban agriculture to the general public. SpiRuBrew creates an innovative way to interactive with the cultivation of personal food sources. The system allows for a continued cycle of data analysis, evaluation, and adaptation in an effort to maximize harvest. Engaging the user in the otherwise unknown science of food cultivation.
