You will often find high salt concentrations in the hydroponic system. Most people use a nutrient solution in hydroponics. Salt build-ups occur when the plants are soaked in the solution for a very long time. The dissolved salt in the solution evaporates faster than the minerals and is absorbed by the roots.

High salt concentration in the surface area causes great damage to the roots; they become mushy and break off easily. The plants also become unable to supply nutrients and water. Sometimes, over-fertilizing can also cause salt build-ups in hydroponics. The main elements of the solution are highly salt accumulated.

To avoid having salt build-ups in the hydroponic system, you can neutralize high salt concentration in the nutrient solution by applying remedies.
