Shopping guidance from Toledo Indoor Garden. Prices, availability, shipping rates, weights, and dimensions are verified during checkout.

NPK RAW Silica contains 45% silicon dioxide in a biogenic, pH-neutral, and highly water-compatible form, one of the highest concentrations available.

Silicon reinforces cell walls and strengthens stems, helping plants bear heavier buds and resist environmental stress including heat, drought, and pest pressure.

It provides non-toxic preventative protection against fungal infections and insect infestations while improving nutrient absorption, transport, and chlorophyll production.

Unlike harsh potassium silicates, RAW Silica is microbe-friendly and can even serve as a carrier for microbial inoculants in living soil systems.
