General Hydroponics Armor Si - 1 Qt

Stronger Plant Structure From Soluble Silicon - 1 Qt Bottle

Plants face heat, cold, high light and handling stress throughout a grow cycle. Armor Si supplies soluble silicon to help strengthen cell walls, support upright growth and improve tolerance to environmental stress. It is derived from potassium silicate, so it also contributes soluble potash.

The 1 Qt bottle suits hobbyists trying a silicon supplement for the first time and growers running a few indoor systems. Dosing is measured in small amounts per gallon, so one bottle goes a long way in a modest setup.
