Hi laura, my question is if this culture is safe to eat (fda?) after harvesting. or is this also for research purpose?

Hi Tim,Spirulina is a safe organism to eat. It is how it is raised and prepared that can become problematic. If it is grown in water with a pH around 10, the probability of problems is lessened. Also cleaning the algae after harvest is advised, and drying helps to kill pathogens. Finally, I must state (as my wife is a lawyer), eating anything you grow at home, be it beans, corn, or spirulina; how you grow it effects the safety of the product. Therefore, we offer no guarantee, warrantee, or prediction of safety if you choose to consume this product or feed it to animals. That said, I have not had any one tell me that they have had any problems.

Spirulina platensis, Spirulina maxima, Spirulina fusiformis? What is it?

To the best of my knowledge they are all the same species. But technically, S. Platenais.

Without adding nutrients, how much can this algae grow in 5 days?

It will contain enough nutrients in the biomass itself (luxury uptake) to likely double. The media it ships with will have enough to more than double as well.

how much solution will this make?

You question is a bit vague I think, but I will answer to the best I can.Infinite if done properly, and continue to build your nutrient solution to feed the algae culture as you harvest.I was able to fill 5 gallons and used less than half of the liter, and it was enough to grow very well. So I will be harvesting and adding more nutrient solution to keep it going. I imagine it's at least enough to start 3x five-gallon tanks, but if you plan on growing it out, you will gain an infinite supply if you take care of it.
