I have a GH Water farm, 3X26w CFL and 2XLED for veg. I put the clones in the other day and the top of the rockwool is turing algae green, the tops of the rockwool are exposed, is this normal?, or even acceptable? I am using GH Flora Grow with Flora Mirco and GH Floralishious (sp). PH is good temp is good ppm is at 250.
Also I have the lights on 18/6 with the pump off with the lights. Should I have 2 timers one for the pump and one for the lights, or can the pump run 18 hrs with the lights.
THANK YOU FOR THE HELP
