Harvest Gold Silica is purified silica sand with naturally occurring nutrients harvested from gold telluride quartz-rich vein deposits from deep within the earth.

Purified through a scientific process, this nutrient-rich compound has been shown to retain up to 40% more water, which provides the plant’s root system with extended contact with all nutrients and fertilizers — resulting in up to twice the yield versus untreated soils.*

Unlike other silicas, that for the most majority are made up of a simple soluble silicon dioxide, Harvest Gold Silica is ORGANIC. The grower, in turn, receives a silica product that is not only a bounty of nutrients but also rich in environmental benefits.

How does Harvest Gold Silica work?


Harvest Gold Silica’s unique granule formation improves soil structure by providing pockets for roots to take over while retaining water.


When watered, silica and the nutrients become bio-available immediately and continue to breakdown and fortify the soil and plant throughout the entire plant’s life cycle.


Retained water plus time-released nutrient breakdown provides the plant’s root system with nutrient exposure over a prolonged period of time, keeping plants well-fed with less need for other additives and work.


Harvest Gold Silica improves cellular structure and plant’s stress resistance, cuts watering time and costs by 40%, amplifies the growth of your plants starting at the roots and increases your ROI with 2X the yield.

You can use Harvest Gold Silica with any type of plant — indoor and outdoor — in any type of climate, any time, in any season. This all-natural compound is non-toxic and safe for use around children, pets, and wildlife.

Apply Harvest Gold Silica and you’ll see the difference!


Boost the yield of all your plants, whether you have a backyard plot or whole acres. Harvest Gold Silica has been shown to increase yields up to 200%* compared to untreated soils. *Actual results may vary.

Lawns and Shrubbery

Add new beauty to ornamental lawns and strengthen active yards to stand up to kids, pets, and entertaining. Hedges and shrubs will also grow fuller and stronger throughout the season.

Indoor plants

Grow fuller plants in smaller spaces, help them acclimate better, and reduce plant stress.

Best of all, Harvest Gold Silica helps save on water, fertilizer, time, and effort in caring for your plants, all year long.
