Growing Spirulina in a Simple DIY Photobioreactor, Home or Classroom, Food Pigment, Fertilizer #GIY

Build a simple photobioreactor from a bucket, LEDs, and an air pump. Grow Spirulina Blue Green Algae for food, fertilizer, pigment, or fun. Can be used as animal feed supplement, biostimulant for plants, or a natural food dye. Beautiful blue green color. This is an awesome science fair project. Great project for Biology classes, exploring growth parameters of cyanobacteria and cellular respiration, and other STEM subjects such as making skills, graphing data, and design. This project is a hands‑on, problem‑based learning experience that will empower students to think critically and be creative while exploring the exciting field of biomaterials. Let's make something awesome together!
