Suitable for hydroponics, coco coir, soil, and soilless media, Armor Si delivers highly available silica and potassium to support healthier, stronger, and more productive plants.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eSilica plays a vital role in reinforcing cell walls, helping plants develop thicker stems, stronger branches, and improved overall structure. This added strength allows plants to better support heavy flowers and fruit while improving light interception throughout the canopy.\u003c\/p\u003e\n\u003cp\u003eArmor Si also helps plants tolerate environmental stresses including heat, cold, drought, and transplant shock. By improving plant resilience and nutrient transport, it promotes healthier foliage, stronger root development, improved growth rates, and higher yields.\u003c\/p\u003e\n\u003cp\u003eThe concentrated liquid formula mixes easily into nutrient reservoirs and is compatible with virtually any feeding program.
