Every grower wants the same thing: strong, healthy plants that deliver high yields and produce a top-quality final product.
The secret to such results is not only in the base nutrition, but in how well plants can utilize that nutrition and how strong their foundation is.

One substance plays a key role in this: orthosilicic acid (Si(OH)₄), also known as monosilicic acid.
And that is exactly what Profs Regulator delivers, in a higher concentration and with additional micro-elements.

In this article you will discover what orthosilicic acid does in the plant, why it is so much better than standard silicon products, and why Profs Regulator is indispensable for the modern grower.

Silicon – the forgotten building block

Silicon (Si) is, after oxygen, the most abundant element in the Earth’s crust. Yet it is hardly available in the natural cycle of plants.

In the soil, silicon is usually present in the form of silicates – stable compounds that plants cannot directly absorb. Only in small amounts is silicon slowly converted into orthosilicic acid (Si(OH)₄), the active and biological form that plants can use.

In natural ecosystems, that limited amount is often sufficient. But in intensive cultivation systems, where plants grow faster and must deliver higher yields, a shortage arises. The result: plants remain vulnerable and fail to reach their full potential.

What is Orthosilicic Acid (Si(OH)₄)?

Orthosilicic acid is the biologically active, soluble form of silicon. The chemical formula is Si(OH)₄.
It is also called monosilicic acid, because it consists of a single silicon atom surrounded by four hydroxyl groups.

Why is this important?
Because this small molecular form can be directly absorbed by the plant through roots and leaves. No conversion required. No waiting. No losses.

This makes orthosilicic acid fundamentally different from all other forms of silicon found in standard products.

What does Si(OH)₄ do in the plant?

Once orthosilicic acid is absorbed by the plant, it spreads rapidly to the areas where strength and protection are needed.

1. Strengthening of cell walls

Si(OH)₄ is incorporated into the cell structure. It makes cell walls thicker and harder, comparable to reinforcing concrete with steel.
Result: stronger, more stable plants that are less likely to bend or break.

2. Improved water management

In the leaves, silicon forms a protective layer in the cuticle. This reduces water evaporation and keeps plants better balanced during heat or drought.
Result: less risk of dehydration and stress.

3. Better uptake and utilization of nutrients

Orthosilicic acid stimulates the uptake of important minerals such as calcium (Ca), magnesium (Mg) and boron (B).
These elements are crucial for cell division, photosynthesis and fruit development.

4. Activation of natural defenses

Plants with sufficient Si(OH)₄ produce more lignin, phytoalexins and antioxidants. These are substances that protect the plant against biotic stress (such as fungi and bacteria) and abiotic stress (such as salt, heat or overwatering).

5. Increased production of secondary metabolites

A healthy, stress-free plant can invest more energy in the production of secondary metabolites such as resin and terpenes.
Result: more intense aromas, better flavor profiles, and a final product with a longer shelf life.

Why other silicon products are less effective

Many commercial silicon products are based on silicates or stabilized forms that are not directly available.

The problem with that:

• They must first be chemically or biologically converted into orthosilicic acid.
• That process is slow and inefficient.
• Only a small portion is ultimately absorbed by the plant.

In other words: you provide silicon, but your plant can do little with it.

Profs Regulator contains directly available orthosilicic acid (Si(OH)₄) in high concentration. No detours, no losses – pure effect.

The power of Profs Regulator

What makes Profs Regulator different from standard products?

1. Higher content of orthosilicic acid (Si(OH)₄)
   Where many products contain low or indirect forms of silicon, Profs Regulator delivers directly available Si(OH)₄ in high concentration.
2. Enrichment with micro-elements
   Profs Regulator also contains a balanced package of micro-elements such as zinc, copper and boron.
   These support processes such as photosynthesis, cell division and natural defense.
3. Faster and broader effect
   Thanks to the combination of directly available silicon and micro-elements, you quickly see results in strength, vitality and yield.

The benefits of Profs Regulator for the grower

When you use Profs Regulator consistently, you see effects at multiple levels:

• Stronger plants: stable, compact growth with sturdy stems.
• Stress resistance: fewer problems with heat, cold, drought or fluctuating conditions.
• More efficient nutrition: calcium, magnesium and boron are better absorbed.
• More resin and terpenes: richer aromas, better flavor and quality.
• Longer shelf life: harvested products stay fresh longer.
• Higher yields: both quantitatively and qualitatively.

Scientific basis and practical experience

Research shows that orthosilicic acid (Si(OH)₄) simultaneously influences several physiological processes:

• It increases the mechanical strength of plant tissue.
• It reduces transpiration rate and optimizes water balance.
• It promotes the uptake of micro- and macro-elements.
• It activates genes involved in stress response and defense.

In practice, this means: growers who use Profs Regulator notice that their crops are more stable, more vital and more productive than with base nutrition alone.

Application in cultivation

The use of Profs Regulator is simple and flexible:

• Dosage: 15 ml per 100 liters of water.
• Application: via irrigation or foliar spray.
• Stages: suitable for all growth stages – from vegetative development to flowering and ripening.

Thanks to the high content of directly available orthosilicic acid, the product works quickly and efficiently, without residues or waste.

Summary – Orthosilicic acid as the key to top quality

Modern cultivation demands maximum efficiency and quality. Base nutrition alone is not enough to unlock the full potential of a plant.

With Profs Regulator, you add the decisive element to your program:

• Orthosilicic acid (Si(OH)₄) / monosilicic acid – the only form of silicon that plants directly absorb.
• Additional micro-elements – for a broader and more powerful effect.
• Proven benefits – strength, stress resistance, better uptake, more resin and terpenes, longer shelf life.

Profs Regulator – the professional choice for growers who put knowledge, quality and results first.
