Has anyone tried growing anthrospira platensis (Spirulina)!?

It's a phytoplankton that's incredibly healthy for humans to eat but I can't find any small scale growers online and am hella confused why...

Hi xfactor1978, I wanted to say :welcome: to TR.
I don't grow any phyto but hopefully someone will jump in with more information.

take a gander over at www.florida-aqua-farms.com and see what they have in the way of materials. I've purposely avoided spirulina as I stick with smaller celled phyto's myself (nannochloropsis, gymnodinium, etc.). In any case googling with the terms "spirulina culturing" may yeild better results.
