Silica Skin

0 - 0 - 1.5 with 4% Silica

The Problem

Silicon is like skin for a plant; it helps form the outer layers of the cell wall to better protect the plant from environmental stressors and disease pressures. Poor silica chemistry ties this valuable element up and decreases the plant’s natural ability to fight off predators.

The Solution

Silica Skin is a source of readily available silicon, which can help thicken the outer layer of cell walls and form a stronger defensive barrier against pests and pathogens.


Silica Skin can also improve plant resistance to drought stress by reducing water loss during times of extreme heat and light intensity.

Silica Skin is our silicon supplement.

It is a natural source of silicon, derived from natural sand, complexed with unique plant-based organic acids. It is 100% available for plants to take up immediately both as a foliar spray and a root drench.

Our unique plant-based organic acid complex allows Silica Skin to be much more stable in reservoirs than many other silicon products; and when used in conjunction with the rest of our line, it will not precipitate or form insoluble gels when used as directed.

Silica Skin is derived from: Fermented plant material (Carthamus tinctorius, Hibiscus sabdariffa) and potassium silicate.

The history of safflower (Carthamus tinctorius) goes back thousands of years, predating Egyptian recordings. It is one of the oldest crops in mankind’s agricultural history.

Its seeds were used to make vegetable oil; and the delicate flowers, which produce unique pigments such as carthamin, were used to dye clothing and crafts.


Hibiscus flowers (Hibiscus sabdariffa) are rich in a wide variety of organic acids: citric, malic, tartaric, and many others including one that is rarely produced by other plants – hydroxycitric acid.

It has been an important and symbolic crop for over 6,000 years in Western Africa, where the whole plant has been used as food and medicine.

General Tips!

• Always start with clean, filtered water. RO filtered water is not necessary.

• Avoid mixing A&B in concentrate. For injection systems, a mixing chamber between pump heads is recommended.

• Take your time mixing between products. You can add things together too fast; it is harder to add them together too slow.

• Wash your measuring cups between products! Or, better yet, get a measuring cup for each one that way you can eliminate cross-contamination altogether.

• Once you have added the correct amount of each product into your mix tank, mix well to homogenize the solution, however, do not use bubblers or aerate the solution.

• If using a feedwater injection system, like a dosatron, regular cleaning of feed lines is recommended. Everything in our products is water soluble, so periodic water-only cycles will clean your lines. After every watering, you can also run just enough plain water to fill your lines and flush out any feedwater solution.

• Clean pumps out with plain water after every use or water with a small amount of peroxide.

Foliar Combinations and Tips

Our products have excellent synergy with each other when used as foliar sprays. Try the following combinations out and let us know what you think!

  1. Solar Rain & Silica Skin – 40mL per gallon of Solar Rain and 20mL per gallon of Silica Skin
  2. CalMag Fuel & Lush Green – 40mL per gallon of CalMag Fuel and 20mL per gallon of Lush Green

Our customers & friends try all sorts of combinations with great results. We’ve seen a lot of things work out very well once people get familiar with the products and learn how to use them as tools that help them achieve the results they’re looking for.

• Do experiment with your own combinations to get the maximum synergy between all of the products, but do not use Primer A&B or Root Anchor as foliar sprays.

• Do use filtered, clean water.

• Do try to spray early in the mornings; but if you have to spray in the middle or end of day, you may not have to turn the lights off.

• Spray a small number of plants first to test their reaction out; most of our customers eventually spray their whole gardens once they get comfortable and trust that our products do not burn plants when sprayed with the lights on.
