I am growing algae (Chlamydomonas) for part of my science fair project. It is not visible in any of the tests I am currently experimenting on. The algae is growing in soil-water medium several petri dishes. They are getting the right amount of light supplied by fluorescent bulbs and the temperature in the room that they are growing in is a fluctuating 15 degrees Celsius. I am wondering about how many days do you think it would take for the algae to become visible in my tests?
