GROTEK GRO-SILIC is a concentrated liquid silicon supplement suitable for soilless and hydroponic systems. This plant-available form of silicon (monosilicic acid) helps improve plant growth and quality, in part by hardening cell walls. Plants with improved cell wall structure are better able to endure periods of abiotic stress such as high temperatures and drought.


GROTEK GRO-SILIC is very effective as a soil drench, but for fastest absorption apply as a foliar spray.


Application Rate: 1L makes 6667L of solution.

Foliar application: Dilute to 1:500 or greater. Apply at the 3 – 8 leaf stage and once monthly thereafter as required. Soilless/water culture application: For nutrient solutions apply at a rate of 0.15 – 0.30 ml/L (0.6 – 1.2 ml/gal.).
