so I think you are right on track with the air gapAlso just wanna say this is completely @EventHorizan fault :cool::mushtache:
He told me to mess with the pH and promised it wouldn't kill my plants... he has a thing for curvy... now bendy is dying. Coincidence?
you def can drownd your plants in hydro
there has to be a gap in order for the roots to get oxygen
even though you oxygenate the water
the real oxygen comes from the gap left inbetween
in coco or better yet rockwool
there are small air gaps in the media that allows oxygen
in things like soil it is easy to kill plants by
by drowning because the airgaps are easily filled with water
but coco and rockwool hold about 20-30% oxygen at full saturation
but if your roots are sitting in water with no oxygen hitting the roots the plant will go byby fast
