Cloning Plants in an Aeroponic System
Plant cloning, as the name suggests, is the process of copying a plant. In hydroponic growing, this involves taking cuttings from a selected mother plant with desirable traits and reproducing it consistently in an aeroponic system.
Cloning in hydroponics is a skill that improves with practice. This guide provides a simple, structured method to achieve consistent results.
Equipment Required for Aeroponic Cloning
To begin cloning in a hydroponic aeroponic system, you will need:
- Aeroponic cloning system
- Cloning gel or rooting solution
- Pipette and plate
- Sterile scalpel
- Glass or container (approx. 1L)
- Water
- Healthy mother plant
Preparing Your Cloning Solution
- Fill a glass or container half full with water
- Adjust water to pH 6.2
This solution will temporarily hold cuttings before placement into the aeroponic system.
Selecting and Taking Cuttings
- Choose cuttings from the middle or lower sections of the mother plant
- Use a sterile scalpel (not scissors) to avoid damaging plant tissue
- Immediately place cuttings into the prepared water
Making the Final Cut (45° Cut)
- Using a scalpel, make a 45-degree cut near the base of each cutting
- Perform this cut under water
Reason: This prevents embolism (air entering the stem), which can slow or stop root development.
Applying Cloning Gel
- Pour cloning gel onto a clean plate
- Remove each cutting from water
- Dip the stem into the cloning gel thoroughly
Setting Up the Aeroponic Cloner
- Insert cuttings into clone collars
- Place collars into mesh pots
- Position each cutting securely in the aeroponic system
Most aeroponic cloning systems include collars and mesh pots designed to support stems.
Preparing the Aeroponic Reservoir
- Fill the system reservoir with 3–6L of water
- Add rooting tonic (if available):
- Example: 1ml per litre
- Turn on the pump
- Place the lid or humidity dome on top
- Keep vents closed to maintain humidity
Optimal Conditions for Aeroponic Cloning
Maintaining correct environmental conditions is critical for fast root development in hydroponic cloning systems.
Key Parameters
- pH: 6.2
- Water temperature: 19–21.5°C
- Humidity (RH): 72–100%
Expected Results
Under optimal hydroponic conditions:
- Root development typically occurs within 5–8 days
Summary
Aeroponic cloning is an efficient method for producing consistent plant genetics in hydroponic systems.
Success depends on:
- Clean cutting techniques
- Stable pH and temperature
- Proper humidity control
- Consistent system operation
With practice, aeroponic cloning becomes a reliable method for rapid plant propagation and uniform hydroponic crop production.
