I have a table I am running ebb and flow style with rockwool cubes 6x6. My question is are the plants being affected badly by the roots popping out of the bottom and being exposed to light? Some are growing a little bit of algae on them. If so what should I do to fix the problem for this crop. The next I will be using coco mat under the rockwool.
Any help would be greatly appreciated.
