I'll be starting a SOG Ebb and Flow Flowering setup and I wanted input on a couple of things. Loose Rockwool or Hydroton in the net cups? Flood frequency during light (no floods during the 'night')? Nutrient bases and supplements? Suggested PPM's during flower weeks 0-2, 2-4, 4-6, 6-8? Also if anybody knows about CO2 dispersal schedules that would be helpful too. Thanks!
