Thanks to its increased size, compared to the GD1, this model allows you to grow up to 70 cm tall plants. This model also has a single LED grow light.
As we can see in Figure 1) GD2 is powered by a low voltage, only 12 volts, which makes it safe for each environment; as shown in Figure 2) you can easily check the level of the nutrient solution.
Figure 3) shows how growth, light and nutrients are monitored and managed by a special microprocessor. In Figure 4) we can see the LED warning light, which turns on when the nutrient solution is running out.
As shown in Figure 7), you have the possibility to change spring/summer daylight hours, while Figure 8) shows how you can turn on the light according to your needs.
As shown in Figure 9) by replacing the hydroponic pot, you can grow your plants using soil and a regular or a terracotta pot. As you can see in Figure 10) this device uses a 20-watt LED light.
Figure 11) shows the size of the device.
