3.2 Light Modes and Timer
Select the appropriate light mode based on your plant's needs:
- Vegetable Mode: Ideal for leafy vegetables and herbs, promoting lush growth.
- Flower & Fruit Mode: Encourages blooming and fruiting for plants like tomatoes and strawberries.
Use the timer function to set the daily lighting duration between 12 and 23 hours, depending on the plant's specific requirements.

4. Maintenance
4.1 Water Level Monitoring and Refill
Regularly check the water level using the float indicator. Refill the tank with water and nutrients as needed to maintain optimal levels. The 14-liter tank capacity allows for several weeks of growth before a full refill is typically required.

4.2 Nutrient Management
Add plant food A and B as directed by the plant food instructions, typically during water refills or full water changes. The frequency and amount depend on the plant's growth stage and type. It is recommended to periodically test the pH and EC (electrical conductivity) of the water to ensure optimal nutrient availability for your plants. Water testing kits are available separately.
4.3 System Cleaning
Perform a full water change and clean the water tanks every 2-4 weeks to prevent algae buildup and maintain water quality. Periodically inspect and clean the water pumps to ensure proper circulation.
5. Troubleshooting
5.1 Pump Not Circulating Water
If the water pump is not circulating, check the following:
- Ensure the power cable is securely connected and the system is powered on.
- Verify that the 'Pump' button on the control panel is activated for the respective tier.
- Inspect the pump for any blockages or debris. Clean the pump thoroughly if necessary.
- Check the water level; the pump may not operate correctly if the water level is too low.
5.2 Poor Plant Growth
If plants are not growing as expected, consider these factors:
- Light Mode: Ensure the correct light mode (Vegetable or Flower & Fruit) is selected for your plant type.
- Lighting Duration: Adjust the timer to provide adequate light hours (12-23 hours) for the plant's growth stage.
- Nutrient Levels: Confirm that plant food A and B have been added correctly and are at appropriate concentrations. Consider testing water pH and EC.
- Water Quality: Perform a water change if the water appears cloudy or has an unusual odor.
- Seed Viability: Ensure you are using fresh, viable seeds.
