I am just wondering if i should put an airtstone in my grow tray or my resevoir. I currenty have it in my resevoir. I don't know if i should have it in both or just one or the other. I have been told that when the pump goes on for the aeration that it creates its own oxygen but I am not sure and just took 40 clones and 6 mothers and do not want any problems. The 6 mothers are in the wooden trays in the pics. Is there a such thing as too much oxygen? I am used to doing hydroponics with pellets as my medium so this is new to me. Any help would be appreciated. Thanks
