Controllers

Using the climate control technology in this category, the individual components of the grow technology, e.g. exhaust air systems, lighting systems, complex Irrigation, heating or supply and exhaust air systems, can be optimally adjusted. This allows perfect results to be achieved automatically. If everything is set perfectly, the instruments then measure the humidity and / or the current temperature in the greenhouse and regulate the exhaust air systems or humidifiers accordingly.

Relevant parameters for climate control

Humidity, air quality and circulation, CO² content, temperature - all possible variables of these parameters are crucial when growing plants indoors. Some plants need a certain environment in order to thrive optimally, but sometimes it is also a matter of providing a room used for plant cultivation with a room climate that is pleasant or at least tolerable for people, or of creating a balance between the needs of plants and people, i.e. avoiding tropical conditions à la "flora and sauna".

Technical aids for climate control include thermostats, heating Elements, exhaust air and supply air controllers, automatic pump systems, fan control, hygrometers and the targeted supply or regulation of carbon dioxide, nitrogen and oxygen. The correct insulation of a growing area and the structure of the equipment is also important, not least in order to be able to work efficiently with the various equipment and not waste energy or labour or invest a lot of money in systems that interfere with each other or release most of the energy into the environment.

Automatic fan control with the help of climate control technology

To optimise the speed of a fan, you need a control unit for the fan. This allows you to set the fan so that it runs at the optimum speed to optimise the temperature and fresh air in the grow room. At the same time, this saves electricity and enables a longer service life for the fan (as it does not have to run at full speed all the time). Another pleasant side effect is, of course, that this also results in less noise. Of course, the best thing of all is fully automatic control of the ventilation level. This is usually done depending on the temperature. A certain upper limit is set for the room temperature and a minimum basic speed that the fan runs at in standard mode. If the temperature is then exceeded, the fan speed is increased in order to accelerate the air exchange and thus return to an adequate temperature. As soon as this has happened, the device falls back to a lower speed.

Particularly sophisticated systems enable the connection and simultaneous control of supply and exhaust air Fans at the same time. This means that an optimum pressure difference is also selected at the same time, which ensures that the performance of the fans is optimally utilised by coordinating them with each other.

Heating control via climate controller

Even the best and most reliable heating system doesn't really help if you have to switch it on and off manually all the time. What may be annoying at most most of the time becomes an absolute knock-out criterion when you're on holiday or simply away. After all, as an ambitious gardener, you don't necessarily want to make yourself a slave to your plant cultivation. So here, too, the eye will quickly wander over the possibilities for automation by means of a sensible form of climate control. Where you can still work simply with a timer for simple cultivation, it quickly becomes desirable to have an overall solution that works as homogeneously as possible with the scope and quantity of the technology used.

For example, if you want to operate a somewhat more extensive lighting system in parallel with the plant heating, it may well be worth using centralised climate control technology. Many controllers therefore offer the option of having the lighting and climate control managed simultaneously by a single device. Depending on the power class of the controller, several NDL lamps of one wattage can be controlled together with the fan heater, for example.

It should be noted during installation that many of these air conditioning control units are supplied with several mains cables for the power supply. The problem here is that each mains connection must be connected to a separate circuit. It is therefore not possible to simply use a multiple socket. Otherwise, the fuses of the devices would no longer work, which would have extremely unpleasant consequences if the worst came to the worst. So if you are unsure about your power supply, it is better to consult a professional electrician to be on the safe side so that you are not left with a burnt-out hut or charred greenhouse at the end of the day.
