General Hydroponics Armor Si™ 0-0-4 is a soluble silicon plant supplement designed to reinforce plant cell walls, support upright growth and improve resilience during challenging environmental conditions. Stronger plant tissue can help plants maintain better structure as they develop leaves, flowers and fruit. Suitable for hydroponics, coco coir, soil and soilless growing media, Armor Si can be incorporated into virtually any base nutrient program. Use it throughout the growing cycle to support plant stature, foliar development, light absorption and tolerance to stresses such as heat, cold, drought, high light and changing environmental conditions.
