Hi I am a first time grower and I had made a completely automated grow tent. I am trying to figure out how to use Oxygen pot systems because I bought the 6 flow site green tree hydroponics recirculating hydroponic system. From what I know the roots have to be half way in the water as but what if the roots have barely left the rockwool? am i supposed to guess where the roots are in the hydroton and figure out half way to set the water. How to I give the roots water? Do I leave them in water in the buckets like a normal hydroponic system with a bubbler or do I have cycles every 15 minutes constantly letting the roots breath oxygen then flooding for 15 min in the hydroton. Please let me know, almost nobody knows anything about these systems and could really use the help.
