Preventing Root rot in hydroponics is probably one of the easiest things to get and to prevent. It’s the result of an unsterile environment and the right conditions.
What Causes Root Rot in Hydroponics?
In hydroponic systems, by over-watering the roots can be caused root rot. It can be tricky because hydroponic is growing plants in water and dissolved nutrients in the absence of soil.
Typically when using the Deep Water Culture system it is possible the root system to do not receive sufficient levels of oxygen. When roots do not get adequate oxygen they suffocate and slowly die. When the roots die, then the upper portion of the plant slowly deteriorates and dies.
Root rot is a major concern in hydroponics, just like it can be outdoors when soil conditions are constantly wet. Bacteria, fungi, and algae can all thrive in those conditions. Further this could leads to grow pathogenic bacteria and fungi.
Once you get root rot on a plant, the roots will turn from a bright healthy white to a slimy brown. Pull all the rotted roots out and throw them in the trash. Your plant will grow new ones in a week or two.
