Hi guys, I'm new to R2R, but just started a phytoplankton culture, from Mercer of Montana. How often should I dose with fertilizer? Only after harvesting? Or is it beneficial to dose again during the process? Also, I am keeping my lights on for about 16 hours a day, give or take..not on a timer, but a when should I harvest? 7 days out, 14?
Thanks for any advice
