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 “flowable” 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 won’t throw off your balance of other nutrients. RAW nutrients are water soluble, ideal for “spoon feeding” plants exactly what they need as their needs change throughout development, allowing for complete control of their needs.

Directions for use:

1tsp = 5ml. 1gal = 3.8L

Add 1/8 to 1/4 tsp per gal in reservoir

Apply as needed in irrigation

A 2 oz. package makes up to 200 gallon, an 8 oz. package makes up to 800 gallon & a 2 lb. package makes up to 3200 gallon.

*As always, moderation is recommended when using additives. Start with very low dosages, see how the plants respond, and add more if necessary.
