Clearex can be used to correct the most common cause of crop failure- the buildup of nutrient salt deposits in soil or soiless grow media. Over-fertilization and high concentrations of mineral based nutrients in grow media can cause shrinkage and death of plant cells due to the excess draw of water through cell walls. This can eventually lead to irreversible wilting of plant leaves and stems. It can also lead to nutrient lockout and crop failure. Clearex draws salts away from plant roots and grow media while helping to maintain equilibrium during periodic or preharvest flushing.
