Adjusting Light Height:
As your plants grow, adjust the height of the LED grow light by sliding the pole upwards. Ensure the light is positioned approximately 2-4 inches (5-10 cm) above the tallest plants to provide optimal light exposure.

The system features an adjustable light pole, allowing the LED grow light to be raised up to 70 cm (27.6 inches) as plants grow. It also highlights the 6-liter water reservoir capacity.
Water Pump Operation:
The silent water pump circulates water and nutrients, providing oxygen to the plant roots. The pump operates quietly at approximately 20dB.

The system includes a silent water pump, operating at only 20dB, ensuring quiet operation. It supports 12 plant pods, providing sufficient oxygenation for roots.

Maintenance
Regular maintenance is crucial for the health of your plants and the longevity of your system.
Water and Nutrient Replenishment:
- Check the water level daily. Refill with fresh water as needed.
- Replenish nutrient solution every 1-2 weeks, or as indicated by the app's reminder system. Follow the nutrient manufacturer's instructions for dosage.
- For best results, perform a full water change every 2-4 weeks to prevent nutrient imbalance and algae growth.
Cleaning:
- Periodically clean the water reservoir and growing deck to remove any algae or mineral buildup. Use a soft cloth and mild soap, then rinse thoroughly.
- Ensure the pump intake is clear of debris.
