RAW Silica contains 45% silicon dioxide, one of the highest concentrations available in a flowable, water-compatible form. pH neutral and clean, it can be used throughout growth and bloom to support strong stems, resilient cell walls, and improved crop performance.
Expanded Description:
Silica is often called the support element in plant nutrition because it reinforces cell walls, strengthens stems, and helps plants stand up to stress. While many silica products are based on potassium silicate, RAW Silica is different. It’s a biogenic silica—naturally flowable, pH neutral, and highly compatible with beneficial microbes.
-
Structural Support: Reinforces stems and cell walls for sturdier growth and better resistance to stress.
-
Microbe-Friendly: Unlike harsh silicates, RAW Silica is biogenic and sometimes even used as a carrier for microbial inoculants—making it ideal for living soil and bio-active systems.
-
Flowable & Versatile: Some particles dissolve immediately for fast plant availability, while others remain in the root zone for gradual release.
-
pH Neutral: Will not cloud solutions or shift pH, unlike many traditional silica supplements.
-
Flexible Application: Can be added at any stage of growth or bloom, in soil, coco, hydroponics, or foliar programs.
RAW Silica is highly concentrated, clean, and available in sizes up to 25 lbs. It integrates seamlessly into all feeding schedules as a cornerstone supplement for plant strength and resilience.
