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
  • 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 to make available to plants. All silicon (Si) products aim to provide your plants with silicon in the only bioavailable form that exists: monosilicic 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 active ingredient loss
  • 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?

It's simple: 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 earlier you use silicon, the better. Try it out; the difference is enormous!

Already using a leading silicon product?

Simple math: 100 ml of Grow Genius silicon fertilizer equals 4 liters of leading brands - but without their drawbacks. You save a lot of money, have fewer tank issues, and will definitely achieve visibly better results with Grow Genius, the pH-neutral 40% monosilicic acid.

Application of Grow Genius Silicon Fertilizer

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

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

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

  • Apply bi-weekly as a foliar spray with 0.5 ml per liter of water.
  • Apply from germination/propagation until shortly before harvest for fruits, vegetables, salads, herbs, and cut flowers.
  • For species with dense or compact flowers, 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 exceeding 30°C.

Biological Application

Grow Genius monosilicic acid (MSA) is not a registered biological product, but it is compatible with mycorrhiza and bacteria-friendly cultivation techniques at the recommended rates. 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 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.


  • Seal the container immediately after use: ethanol evaporates quickly!
  • Make sure no water or dirt enters the container: Grow Genius silicon fertilizer will repolymerize upon contact. Use a pipette or other suitable tool to measure the required amount (pipette included in the 10ml size).
  • Contains ethanol and silicon: safe for plants under normal use, but not for direct contact with humans: do not ingest, inhale, or allow contact with eyes/skin.
  • Always avoid inhaling the spray mist of this or any other garden product: 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.
