your soil to grow your plants fuller and faster.

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

Harvest Gold Silica can improve the growth and yield of:


*Actual results may vary.

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.*

And it’s 420-friendly!

How does Harvest Gold Silica work?


The silica contained in Harvest Gold Silica retains water due to its unique granule formation.


Water is retained in the soil, allowing the micronutrients to breakdown over time.


Retained water plus time-released nutrient-breakdown makes the nutrients available to the plant’s root system over a prolonged period of time.


Retained water plus prolonged nutrient exposure results in 2X more plant growth and average 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 consistently 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.

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.
