How to choose a hydroponic system

In this blog: an overview of 5 key systems, ideal for different experience levels, budgets and plant types.

1. Kratky method (does not require energy)

Description:
Static system without pump or aeration – plants are placed in covers above a tank of nutrient solution. As they grow, the solution level drops and an air gap is created, stimulating “oxygen roots”†. Suitable for leafy greens and herbs only.

✅ Advantages:

• No electricity, pumps or timers needed.
• Very low maintenance, easy start.
• Economical — ideal for home hobbyists.

❌ Disadvantages:

• Only for small plants.
• No possibility of replenishing the solution during the cycle.
• Not suitable for commercial use.

2. Deep Water Culture (DWC) method

 

Description:
The plants are kept in baskets above oxygen-rich, nutrient-rich water. The water has aerators and a pump to ensure a constant flow.

✅ Advantages:

• Easy installation and maintenance.
• High oxygen levels, constant nutrition.
• Also suitable for larger (but not sucker) plants.
• An excellent choice for beginners.

❌ Disadvantages:

• Electric pump and air compressor required.
• Higher initial costs.
• Requires monitoring of pH and temperature.

3. Drip System Method

Description:
Nutrient solution is delivered drop by drop through a network of drip tubing, with the excess returned to the reservoir or discarded.

✅ Advantages:

• Precise dosing of the nutrient solution.
• Automation and flexibility.
• Effective for almost all types of plants.

❌ Disadvantages:

• Higher installation investments.
• Needs reliable filtration and pH management.
• Possibility of blockages.

4. NFT (Nutrient Film Technique) method

Description:
The plants are placed in channels through which a thin layer (filmuLieu) of nutrient water moves. The roots touch the flowing film, while their upper part remains dry.

✅ Advantages:

• Excellent efficiency in watering and feeding.
• Oxygen is available directly from the air.
• A suitable system under optimal conditions.

❌ Disadvantages:

• Requires an electric pump and a stable electrical supply.
• Risk of blockages and pH increase during recirculation.
• Doesn't work well with tall plants.

5. Method Aeroponics (Aeroponic System)

Description:
The roots hang in a closed chamber and are periodically moistened with a fine mist of solution. Maximum oxygen levels and minimal water consumption.

✅ Advantages:

• Best water and nutrient efficiency.
• Optimal air circulation around the roots.
• Excellent for vertical crops and limited spaces.

❌ Disadvantages:

• Highest initial costs.
• Complex maintenance and need for precise cycle management.
• Sensitive to power outages.

Which system is right for you ?

Level/needs	Recommended system
Beginners / small garden / low budget	Kratky or DWC
Mid-level/high-control home garden	Drip System or NFT
Professional / vertical / maximum yield	Aeroponic System

When choosing, consider:

• Experience level
• Startup and maintenance budget
• Plant type (Kratky is ideal for leafy greens, not tomatoes or cucumbers)
• Energy access / stable power supply
• Spatial constraints

? Conclusion and next steps

Hydroponics offers a sustainable and energy-efficient way to grow both home and professional gardening. With the right system for your experience, goals, and budget, you can achieve significant yields with minimal resources.

Start with the Kratky method for simplicity or the DWC method for easy expansion. If you are looking for more control and automation — go for Drip or NFT. If you want maximum efficiency and space is a priority — an aeroponic system is for you.
