Key Prompts and What They Mean

  1. When the power adapter is plugged into the grow box and switched on at the mains socket, the system will sound a long “beep” to indicate it is ready to work.
  2. After the machine runs for several days, the water level in the tank will naturally fall. When the water level is no longer sufficient for the plants to grow, the machine will sound a long “beep” to let you know. If this happens, please refill the tank to the correct amount. Once you have done this the alarm will automatically stop beeping.
  3. When the system is working normally with the light on, a shorter “beep” will sound when you press any button. If the mode is being changed, the light brightness will correspond accordingly.
  4. If a button on the panel is pressed when the machine is turned on and the light is off, the machine will make a short “beep” sound. If it does not make
    a beep when a button is pressed, it is likely that the system is not switched on properly. If this occurs, try the following:
    • Check if the machine is connected to the main power supply.
    • If the machine is connected to power but in a dormant standby state, press the power button to test it. When the power button is pressed in the dormant state, the light will go off after 3 blinks.

Box Contents

Before using your grow box, please check that you have everything you need:

Set-Up Instructions

1. Using one hand on the extendable rod, and one hand holding the water tank down, gently pull the rod upwards to extend it higher. Do not use the light panel to extend the rod.

2. Remove the water tank cover and take the accessories out of the tank; power adapter, planting package, and 2 bottles of nutrients.

3. wash your water tank before use, first you will need to remove the tank cover and then gently pull out the light panel.

4. After washing and drying the tank, you can reinstall the LED light panel using one hand while holding the water tank down with the other hand.

5. Assemble the power system at the bottom of the water tank. When it is all assembled and ready for planting, plug the power adapter into the socket.
When the power is properly connected, the system will make a “beep” noise, letting you know it is ready to use.

Preparing the Nutrient Solution

1. Fill bottle ‘A’ with water, put the lid on, and shake to fully mix the contents until fully dissolved. Repeat the same with bottle ‘B’.

2. Using the measuring caps, add 5ml of each solution to 1 litre of water. Stir or shake well to combine it all together.

Planting Instructions

1. Prepare the nutrient solution as shown above.
2. Remove the grow box lid and pour the mixed solution into the plant pot.
Place the plant pot lid back on top.
3. Soak the seeds in warm water for about an hour before planting. Place a
sponge into each basket. Sow the seeds properly in each plant basket, then
place the baskets into the spaces on the grow box lid.

Using the Control Panel

NORMAL CYCLE: 14 hours on / 10 hours off

Press this button and the system will be switched on. It will sound a “beep” and run in ‘normal cycle’ mode. This means the LED light panel will light up for 14 hours. It will then switch off for 10 hours. The following day it will repeat this pattern: 14hrs on / 10hrs off.

SHORT CYCLE: 12 hours on / 12 hours off
If you press this button, the system will sound a “beep” and enter the ‘short cycle’ mode. The LED panel on the top will reduce the intensity of the light and will start a cycle of 12 hours on / 12 hours off.

LONG CYCLE: 16 hours on / 8 hours off
If you press this button, the system will sound a “beep” and enter ‘long cycle mode. The LED panel on the top will increase the intensity of the light and will start a cycle of 16 hours on / 8 hours off.

Setting the Mode
From the moment the system is connected and switched on at the plug, the power button will illuminate and the lamp will be in ‘standby mode.

When you select a mode, it will turn on the lamp and activate a 24-hour clock to coincide with the cycle of the mode you have chosen. Depending on the time you first selected the mode, this will be the same time that the light turns on every day thereafter.

For instance, if you select the ‘normal mode’ at 10 am for the first use, the system will run the cycle of 14 hours lights on and then 10 hours lights off. It will then automatically turn back on at 10 am the following day, and the cycle will continue for as long as desired until the unit is either turned off into ‘standby mode’ or switched off at the plug.

24 Hour Light-On Setting
If you wish to keep the light working all day long (for a whole 24 hours), hold the power button down for 3 seconds.

The light will blink 3 times, then the whole system and lights will switch on and stay on for 24 hours. After this time elapses, the system will automatically revert back to ‘standby mode.

If you activate this 24-hour light mode while the lamp is currently working, it will keep the lamp lit constantly until the end of the programmed cycle and then revert back to the mode you had been using previously.

Care and Maintenance

Before cleaning ensure the lamp is unplugged from the mains socket.
Do not submerge this lamp in water or any other liquid. Do not use corrosive cleaning products on it.
To clean, simply use a dry cloth to dust and clean the lamp.

Storing the Nutrient Mixture

  • The dry unmixed nutrient particles have a storage life of 2 years if kept in an unopened bottle in a cool dry place away from direct sunlight.
  • The mixed nutrient mix (with water already added) has a storage life of 5 months if stored away from sunlight.
