General Hydroponics Armor Si

Armor Si 0-0-4 is a silicon supplement that supplies soluble silicon to help reinforce plant structure and support stronger, more resilient growth. Silicon helps strengthen plant cell walls, supports upright growth and improves tolerance to environmental stress such as heat, cold and other abiotic pressure. It also supports foliar development and light absorption, improving overall plant stature. It is suitable for all plant types across all growth stages.

Add Armor Si to fresh irrigation water before adding base nutrients or other supplements, then continue building the solution. It is used throughout the entire grow cycle, from early growth through flowering, following label directions and the selected feed chart. Standard dosing runs about 1 to 2 mL per gallon during vegetative and early flowering stages, with aggressive applications reaching up to 5 mL per gallon under high-demand conditions. It is compatible with hydroponics, coco, soil and other growing media.
