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 stress such as high temperatures and drought.
