How does a closed grow box work?

Fridge Grow is a closed system with no air exchange with the installation room. Due to the design and insulation of the installation room, any climate can be constantly and stably controlled inside without the influence of external factors. Whether in the attic in summer or in the garage in winter – the climate can be individually regulated.

The system assumes that plants are in it and that they “sweat”, i.e. they increase the humidity. Therefore, a test run without plants only makes sense in greenhouse mode. If the humidity increases, the cooling is activated and ensures that the moisture in the air condenses at the cool point, making it drier in the system. The water from the air condenses on the cool back wall and flows downwards following gravity, where it is collected in a bowl and returned to the plants. This means that watering only needs to be done every 2-3 weeks.

 

 

This regulates the humidity, i.e. more leaf mass means a greater increase in humidity. However, cooling not only lowers humidity, but also the temperature. However, the LED lamp and an integrated heater increase the temperature again. The dimming ensures dynamic adjustment of the temperature. For this reason, in some cases it can happen that the LED lamp does not work at full power.

 

 

Since there is no air exchange with the environment, CO2 can/must be added as the plants consume it. CO2 is supplied via small CO2 cylinders, such as those used by SodaStream, and these bottles can be sold at supermarkets or similar. can be refilled. Due to the closed cycle, gaseous fertilization can therefore also be carried out with CO2, which in turn leads to better growth. The CO2 value can be determined individually.

 

 

This means that the closed system of the grow box allows temperature, humidity, CO2 and light to be regulated freely and constantly, regardless of the installation space, and even watering is done without tanks or pumps.
