Organic hydroponics

Difficult.

Explanation:

Excess water makes it very difficult for the roots to get the air that they need

Causes:

poor drainage
usually, this is a result of overwatering.
heavy soil, such as one dug up from outdoors
in hydroponic applications, if the water is not properly aerated
Many cases of root rot are caused by members of the water mold genus Phytophthora; perhaps the most aggressive is P. cinnamomi. Spores from root rot causing agents do contaminate other plants, but the rot cannot take hold unless there is adequate moisture. Spores are not only airborne, but are also carried by insects and other arthropods in the soil.

Prevention:

only water plants when the soil becomes dry
put the plant in a well-drained pot
Root rot and other problems associated with poor water aeration were principal reasons for the development of aeroponics.
