whats everyone's favorite medium for Ebb n flow table growing?
Coco, Rockwool or Hydroton/Grow Stones?
I have used all but Coco but i'm paranoid to try Coco for Ebb and Flow because i read that Canna does not recommend that method for their Coco and i know they have the best Quality Control on the stuff they bag. They say that the CEC of the Coco will eventually leach sodium and potassium back into the reservoir and bind with your nutrient solution and lock certain elements out.
