The used LED technology - developed in cooperation with Humboldt University - imitates sunlight and gives plants exact amount of light, which they need for optimal growth. The LED lights have a total power of ca. 30W, which equals to the energy use of a small light bulb (14 kWh/month with a  suggested cycle of 16h a day). In contrast to other vertical farming devices our system is also concentrated on user’s well-being and creation of positive indoor atmosphere - that is why we use LEDs imitating sunlight spectrum, which are pleasant and relaxing to eyes, instead of typical for industrial vertical farms combination of red and blue lights.
The light settings can be adjusted by the consumer. The customer can adjust the turn off and on time to his own needs and that way use the GreenBox even as a sunlight alarm clock!
