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.
Gro-Silic is very effective as a soil drench, but for fastest absorption apply as a foliar spray.
