Hydro Gurus, Submerged Roots?

[NEWGROHYDR0]

After a heated debate im looking for hydro gurus.


IN A FLOOD AND DRAIN BUCKET SETUP, WHERE A BRAIN FEEDS FROM A RESEVOIR TO BUCKETS, ROOTS NEED OXYGEN AND CANNOT BE CONTINOUSLY SUBMERGED, CORRECT?


Thank you for your comments.

You can leave some of the roots submerged as long as you provide aeration for the water (air pump + air stone).
But not all of them, and not without aetaion.

So if root tails are submerged in water and say 65-80% of roots are in medium, only water on cycles, than the roots will not suffer any form of algae or over-waterization?


Thank You.

I would shoot for 20%--30% continuously submerged roots.

I use 3 rainforest systems when vegging. I would say 80- 90 percent of the roots are submerged when the resevoir is full in my systems. I have an airstone in each system that's constantly on. The key is having a good oxygen supply in the water at all times.
