Everything fails in the hydroponic pot growing world if the dissolved oxygen is too low. Of course the O2 gas must be dissolved in res water and if there is not enough dissolved available continuously 24/7, roots die, Bennies die decay sets in the fungal outbreak invade tour and eat well.
Air is always called oxygen and visa-versa, but air is a mixture of elemental gases. Aerobic plant roots and Bennies don’t need nor do they consume Nitrogen and air is 80% elemental Nitrogen gas.
So does somebody, anybody have a clue what the “safe DO range” is for any hydroponic pot grow? Like actually measured with a DO Meter. You know like actually measuring pH is commonly tested with a meter of chemical test or testing res water temp and air temp with a thermometer or humidity with a hygrometer.
