Setup
- Assemble the System: Insert the adjustable light pole into the base unit. Attach the LED grow light panel to the top of the pole. Ensure all connections are secure.
- Prepare Seed Pods: Place a sponge into each plant basket. Soak the sponges in water for 5 minutes before placing seeds. Insert your desired seeds into the center hole of each sponge.
- Place Seed Pods: Insert the prepared plant baskets into the designated holes on the planter panel. If not all pods are used, cover empty holes with the provided hole covers to prevent algae growth and water evaporation.
- Add Water and Nutrients: Open the water inlet cap on the planter panel. Fill the 10L water tank with fresh water up to the 'Max' line indicated by the water viewing window. Add the appropriate amount of Nutrient Solution A and B as per the instructions on the bottles (typically 5ml of A and 5ml of B per liter of water).
- Connect Power: Plug the power adapter into the system's power port and then into a wall outlet.
- Initial Settings: Press the Power button on the control panel to turn on the system. The default light cycle is 16 hours on and 8 hours off.
