Armor Si™ is a silicon supplement that helps reinforce plant structure and support stronger, more resilient growth. It can be used with all types of plants, across all stages of growth, and in hydroponics, coco, soil, and other growing media.

Armor Si™ supplies soluble silicon to help strengthen plant cell walls, support upright growth, and improve tolerance to environmental stress. It also supports foliar development, light absorption, and overall plant stature when used alongside a regular nutrient program.

Add Armor Si™ to fresh irrigation water before adding base nutrients or other supplements. Use throughout the grow cycle, from early growth through flower, following label directions and your selected feed chart.

Plants are constantly exposed to stress from heat, cold, high light, handling, and changing environments. Armor Si™ gives growers an added layer of structural support, helping plants stay strong and perform consistently through demanding conditions.
