RAW Silica by NPK Industries is a technical grade plant supplement that is used for horticultural purposes. Raw silica contains 45% silicon dioxide, the highest concentration available to the home gardener and is a âflowableâ or biogenic source that sticks with the roots and provides far more benefits than silicon alone. Unlike other silica products raw silica is relatively pH neutral and wonât throw off your balance of other nutrients. RAW nutrients are water soluble, ideal for âspoon feedingâ plants exactly what they need as their needs change throughout development, allowing for complete control of their needs.
