40% Mono Silicic Acid - Silicon Fertilizer

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

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

Note: Silicon is very difficult for plants to make available. All silicon (Si) products are designed to deliver silicon to your plants in the only bioavailable form there is: mono silicic acid (MSA). Grow Genius 40% MSA Silicon Fertilizer delivers exactly 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 slow release
  • Unique: no precipitation, no loss of active ingredient
  • Unique: pH-neutral & biodegradable

Grow Genius Silicon Fertilizer enhances natural growth and resistance for 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/pruning damage.
  • Toxicity from heavy metals and other unwanted elements in the soil.

Never used a silicon product before?

Simply put: Bioavailable silicon is missing from all modern, otherwise optimized fertilizers. By adding silicon fertilizer, you'll get significantly larger, more robust plants with improved heat, pathogen, and pest resistance. The sooner silicon is used, the better. Give it a try; the difference is enormous!

Already using a leading silicon product?

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

Application of Grow Genius Silicon Fertilizer

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

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

For building defense against pests, mold, and other fungal pathogens

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

Biological Application

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


  • Seal 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. Therefore, use a pipette or another suitable tool to measure the required amount (pipette included with 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 let it come into contact with eyes/skin.
  • Always avoid inhaling the spray mist of this or any other garden product: always wear appropriate mask, eye, and hand protection when working with garden chemicals.
  • Detailed handling and safety information can be found on the product packaging and in the safety data sheet.
