Grotek Gro Silic

Grotek Gro Silic is one of the most interesting supplements to add to a nutrient program. While not considered essential, silica assists numerous plants with abiotic stress. Gro-Silic has elevated levels of plant available silica to help with heat, drought, and salinity, providing improved uptake within plant structures when compared to other slower release forms of silica.

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.
