40% Monosilicic Acid - Silicon Fertilizer

Ultra-fast acting silicon fertilizer suitable for all plants in all environments. It enhances nutrient utilization efficiency and plant tolerance to abiotic stress.

  • pH-neutral
  • extremely low heavy metal concentration
  • readily available
  • stable
  • long-lasting effect
  • integrated surfactant
  • 40 times the concentration of conventional products
  • Free from unnecessary NPK, molybdenum, or boron
  • No more clogged pumps and hoses
  • No dirty tanks
  • Not based on potassium silicate

Note: Silicon is notoriously difficult for plants to access. All silicon (Si) products aim to deliver silicon to your plants in the only bioavailable form there is: monosilicic acid (MSA). Grow Genius 40% MSA Silicon Fertilizer delivers just that – in the most concentrated, cost-effective, and environmentally friendly way currently available!

  • Unique: 40% strength (0.03 ml/L in solution)
  • Unique: Ultra-low heavy metal concentration
  • Unique: 7-day extended release
  • Unique: no precipitation, no active ingredient loss
  • Unique: no hose and dropper clogging
  • Unique: pH-neutral & biodegradable

Grow Genius Silicon Fertilizer enhances natural growth and defense mechanisms, resulting in larger, healthier plants with increased resistance to:

  • Powdery mildew, botrytis, black spot disease, and other fungal pathogens.
  • Thrips, mites, aphids, and other biting and piercing pests.
  • Heat stress, water stress, and strong winds / damage from pruning.
  • Toxicity from heavy metals and other unwanted elements in the soil.

Scenario 1 => You've never used a silicon product before?

Put simply: Bioavailable silicon is missing from all modern, otherwise optimized fertilizers. By adding silicon fertilizer, you will get significantly larger, more robust plants and improved heat, pathogen, and pest resistance.
The earlier you use silicon, the better. Try it out; the difference is enormous!

Scenario 2 => You're already using a silicon product from another manufacturer?

Simple calculation: 100 ml of Grow Genius Silicon Fertilizer is equivalent to 4 liters of leading brands - but without their drawbacks.
You save a lot of money, have fewer tank problems, and achieve guaranteed visibly better results with Grow Genius, the pH-neutral 40% monosilicic acid.

Application of Grow Genius Silicon Fertilizer

1. For strength and yield increases, faster growth, and stress resistance

  • Weekly application with 0.3 ml per 10 liters of water or mixed with nutrient solution.
  • Hand watering / through irrigation system.
  • Apply from seed germination or cuttings propagation until a few weeks before harvest.

2. To build resistance against pests, mold, and other fungal pathogens

  • Bi-weekly as a foliar spray with 0.5 ml per liter of water.
  • Apply from seed germination/propagation until shortly before harvest for fruits, vegetables, salads, herbs, and cut flowers.
  • For species with dense or compact flowers, stop foliar application at the beginning of the flowering period, especially indoors or in cold or wet weather.
  • Do not spray under full light, in strong sun, or at temperatures above 30°C.

3. Application in organic farming

First off: Grow Genius Monosilicic Acid (MSA) is currently not a registered organic product, but it is compatible with mycorrhiza and bacteria-friendly cultivation techniques at the recommended application rates.
Silicon is not harmful to most beneficial microorganisms, and small amounts of ethanol are digestible by many soil bacteria and fungi. Most importantly, the net addition of silicon to the soil is tiny due to the high concentration of monosilicate: only 0.03 ml/L in solution.
That's the advantage when treating trace elements as they should be: like vitamins, not like food.

Monosilicic acid (also known as orthosilicic acid and silicic acid) has a strong effect at very low doses, which means less effort and better results for your plants overall.


  • Close the container immediately after use: Ethanol evaporates quickly!
  • Make sure no water or dirt gets into the container: Grow Genius Silicon Fertilizer will repolymerize upon contact. Use a pipette or another suitable tool to extract the required amount (pipette included in the 10ml size).
  • Contains ethanol and silicon: Safe for plants when used as intended, but not for direct contact with people: do not ingest, inhale, or allow contact with eyes/skin.
  • Avoid inhaling the spray mist of this or any other garden product: Always wear appropriate mask, eye protection, and gloves when working with garden chemicals.
  • Detailed handling and safety information can be found on the product packaging and in the safety data sheet.
