KALIX K-Silicate (Soluble) 25LB ventilation and ducting The CubeCap deprives the cubeKALIX K Silicate is 100% water soluble potassium silicate derived from silica and potassium oxide. Silica has been found to strengthen cell walls giving plants an increased resistance to environmental stress. Use as directed as a readily available source of potassium and silica during all stages of plant growth. Concentrated potassium silicate will react with other elements, so it is best to be added to solution prior to other nutrients or diluted
