How to effectively clean an irrigation system and a hydroponic system?

A good maintenance of irrigation systems and hydroponic growing systems is essential to prevent blockages, nutrient buildup, and pathogen proliferation. Regular cleaning helps to optimize plant growth by ensuring smooth circulation of nutrient solutions and optimal oxygen supply. This article explains how to effectively maintain your system with the right products and best practices.

Why is it crucial to clean your irrigation and hydroponic system?

A poorly maintained hydroponic growing system can cause numerous problems, including:

• The obstruction of pipes and drippers, reducing the efficiency of irrigation.

• The accumulation of biofilm promoting the development of pathogens.

• A modification of pH and a decrease in root oxygenation, impacting plant health.

The types of deposits and fouling in a hydroponic system

• Biofilm and bacteria : a thin viscous layer that develops on the internal surfaces of conduits.

• Mineral deposits and limestone : accumulations of mineral salts from the nutrient solution.

• Organic residues and unabsorbed nutrients encourage the growth of algae and mold.

Recommended products for cleaning an irrigation and hydroponic system

• Aptus System Clean : a powerful oxidant preventing blockages and biofilm formation.

• Hydrogen peroxide (H2O2 - Oxygenated water) : effective against bacteria and algae.

• Peracetic acid powerful disinfectant against micro-organisms.

• Sodium hypochlorite (diluted bleach) effective but to be used with caution.

• Enzymes and biodegradable products solutions plus ecological for gentle maintenance.

Cleaning methods: step by step

1. Initial rinse

Before any treatment, flush a large volume of water to remove solid residues.

2. Chemical disinfection

Add the chosen cleaning product (H2O2, peracetic acid, etc.) according to the recommended dosages.

3. Mechanical cleaning

Brush the critical areas, including the ducts and pumps, to remove stubborn deposits.

4. Final rinsing and pH check

Once the cleaning is complete, perform a final rinse and check that the pH is stable before reintroducing the nutrient solution.

Preventive maintenance to avoid blockages

• Clean the system every 2 to 4 weeks.

• Use gentle cleaners continuously (e.g.: Aptus System Clean in low dose).

• Inspect and clean the filters and drippers regularly.

Common mistakes to avoid when cleaning

• Overdosage of oxidizing products, risking burning the roots.

• Dangerous mixture of chemical substances, which can generate toxic gases.

• Forgot to rinse, leaving harmful residues in the system.

Comparison of the best cleaning products

Specific cleaning according to the type of hydroponic system

• NFT (Nutrient Film Technique) prefer a gentle disinfectant to avoid damaging the exposed roots.

• DWC (Deep Water Culture) to oxygenate the water by regularly adding H2O2.

• Drip System clean the drippers and pipes frequently.

• Aeroponics to prevent clogging of the nozzles with a strict cleaning regime.

Regular cleaning and the use of the right products ensure a hydroponic growing system that is healthy and efficient. By following these best practices, you maintain the health of your plants and maximize their growth.

FAQ

1. What is the ideal cleaning frequency?

It is recommended to clean the system every 2 to 4 weeks and to perform regular preventive rinsing.

2. Can white vinegar be used to clean a hydroponic system?

Yes, white vinegar can be used to dissolve limescale, but it is less effective against pathogens.

3. Is hydrogen peroxide safe for plants?

Yes, in low doses. An overdose can oxidize and damage the roots.

4. Can different cleaning products be mixed?

No, some chemical mixtures can produce dangerous reactions.

5. How to prevent blockages without chemical cleaning?

The use of filters, regular rinsing, and natural enzymatic solutions can help limit deposits.
