Optimum Hydroponix Silicate 1L Dutch Nutrient Aquaponics - are also idealOptimum Hydroponix Silicate is an easy to use liquid formulation of potassium silicate (K2Si) to provide supplemental silicon and potassium. Applying silicon has been shown to enhance plant growth and increase tolerance to environmental stresses such as cold, heat or drought like conditions by helping to reinforce plant cell walls. Especially useful in hydroponic applications where adequate supplies of silicon are not readily available. Guaranteed
