Hi Loyal Customer's,

We are currently back-ordered with this product for quite some time. We are hoping to be receiving another shipment in about a month but do not have an accurate ETA. Our supplier is working very very hard to get this product shipped to us as soon as possible. We sincerely appreciate your patience and business. Please be aware if you purchase this product there will be a rather large delay in receiving this item. 


Grow-Sil Natural Silica is a 99.9% pure amorphous silica made from rice hulls. Grow-Sil is the highest purity biogenic silica available to growers today.  Many conventional silica/silicate products contain 4%-45% silica.

This product contains 99.9% pure silica, allowing growers to use 1/2 of the product they would normally need to use to achieve optimal results. The raw material source, rice hulls is sustainable. The traditional source for competing lower grade silica, diatoms, is not sustainable.

Grow-Sil can be used as soil amendment at any stage of a plant's life cycle. Silica benefits include strengthening cell walls, protection from stress and fungal diseases, and improved uptake of necessary nutrients and minerals.
