I’ve always wonder why we do have to be cautious about “drowning” a plant, I read that it could prevent plant from getting enough oxygen but how come water-only provides enough oxygen.
In: Biology
Water is one part oxygen. Plants in soaked soil rot because the soil stays too wet for too long and compacts around the roots, “suffocating” them. When growing hydroponically, there is nothing but water and inorganics like leca or perlite that do not compact. The water is either constantly flowing or is changed frequently to keep the oxygen level up.
Basically wet soil is mud that gloms onto roots and blocks oxygen uptake leading to rot and eventual death of the plant.
