PHOTOCATALYTIC GROWING BENEFITS

Traditional indoor cultivation is energetically inefficient by design

The systemic problem of conventional indoor cultivation

The classic indoor cultivation model is based on permanent negative pressure: continuous air extraction to control odor, temperature, and humidity.

• - Constant loss of conditioned air.
• - Expulsion of CO₂ useful for photosynthesis.
• - Continuous MASSIVE intake of spores, dust, and external contaminants.
• - Structural dependence on carbon filters.
• - Recurring replacement costs.
• - High energy consumption.

It is not an isolated flaw. It is an environmental architecture that can be optimized from its foundation.

Environmental technology without oxidant emission into the air

Photocatalysis is an environmental technology. But here something fundamental occurs: it does not release oxidants into the air.

UV-A activation of titanium dioxide (TiO₂) generates highly reactive hydroxyl radicals (•OH). The key is not the “strength” of the reaction. It is where it occurs.

The radicals are generated and remain on the photocatalytic surface. They do not enter the environment. They do not accumulate in the air. They do not circulate within the breathable volume.

They react only when a contaminant molecule comes into contact with the surface. After the reaction, the active site regenerates instantly under UV-A irradiation.

• - Controlled and confined oxidation.
• - No environmental emission of oxidants.
• - Protection of plant health.
• - Protection of people.
• - Preservation of organoleptic qualities.

🔬 Scale and proportion (non-technical explanation)

Imagine a towel the size of a football field...

Now think about different amounts of water on it:

• - Four drops of sweat.
• - A spilled bottle.
• - A barrel.
• - An entire container.

Even at elevated concentrations (1000 ppm), contaminants represent only about 0.1% of the volume. That is much closer to a few drops on an enormous surface than to a barrel or a full container.

An activated photocatalytic surface can present on the order of 10²⁰ reactive sites per square meter.

The reaction does not occur in the air. It occurs on the surface.

The system operates under a regime of massive excess reactive surface relative to the contaminants present.

The detailed quantitative explanation is developed in the Technical Document.

Global ENERGY efficiency optimization

Redesigning environmental airflow

By treating the air within the cultivation volume itself:

• The need for constant air extraction is reduced.
• Thermal retention is improved.
• CO₂ residence time is optimized.
• Structural dependence on activated carbon is decreased.
• Energy and maintenance costs are reduced.

The oxidation of organic compounds generates CO₂ as a byproduct, indirectly contributing to the carbon balance when the system is properly dimensioned.

Lighting and energy coherence

Synergy between LED lighting and the photocatalytic system

Traditional sodium lamps generate a high thermal load, requiring higher extraction rates.

The transition to LED:

• Reduces thermal emissions.
• Stabilizes the microclimate.
• Allows operation with lower forced air renewal.
• Increases air contact time with active surfaces.

System design must always be evaluated considering climatic conditions and geographical location.

Beyond odor elimination

Additional benefits of the photocatalytic coating

In addition to effective odor reduction:

• Absorbs UV-A for activation and reflects the visible spectrum, improving lighting efficiency.
• Acts as a diffusive surface in shaded areas.
• Exhibits self-cleaning capacity through oxidation of deposited organic matter.
• Reduces biofilm formation and dust accumulation.
• Decreases maintenance requirements.

A new environmental control model for indoor cultivation

From filter to integrated system

It is not about adding another device.

It is about rethinking the environmental architecture of cultivation.

Moving from exclusive dependence on filtration and extraction, to integrating surface treatment, energy efficiency, and airflow redesign.
