Botanicare CLEAREX ™ is a scientifically formulated isotonic drench solution, which effectively binds with the excess nutrient salt and safely leaches it from the soil. Leaching with tap or deionized water can lead to hyptonic conditions which cause cell lycis with outflow of essential electrolytes and nutrients. This causes tissue damage leading to serious pathogen disorders such as bacterial and fungal infections. CLEAREX ™ is isotonic, therefore, it creates a safe osmotic environment which allows plant cells to maintain an optimal turgor pressure during treatment.
