Humidity control

So, it is clear that it is necessary to control the humidity in a grow box. It is impossible to do it by eye. In this case you cannot do without a special device - a hygrometer. It can be purchased at any specialized store. There are models with electronic display or pointer, with remote or built-in sensor, built-in thermometer or without it.

Pointer hygrometers are the most economical variant, but they do not allow to control the value as precisely as possible. When growing mature plants, this option is considered acceptable. But if you need more accuracy, as in the case of wanting to germinate tricky exotic plants, you should consider electronic models. Digital hygrometers can have different functionality, often equipped with remote sensor, which is placed near the plant itself. In this case, the level will change as accurately as possible. You can buy the equipment in a specialized store, here you can also buy plant protection products.

How to increase humidity in a grow box

When growing plants in the apartment often the question arises, how to raise the humidity in a grow box. You can do it with your own hands in several ways:

Periodic spraying, the water in this case should come in a finely dispersed state;

Installation of a container with wet expanded clay.

However, these measures do not allow to increase the indicators for a short time. To solve the problem of over-dried air will allow a humidifier.

These devices differ in the principle of functioning, it is customary to divide them into several categories:

Steam humidifiers, by the mechanism of operation resemble an ordinary electric kettle. Can be used only to create conditions for tropical climates.

Ultrasonic humidifier - Safety device, producing steam with the help of an ultrasonic membrane. Many are equipped with a hygrometer so that the humidity in the grow box can be controlled automatically. In this case, the temperature of the steam is no more than 40 degrees.

Air washer. This device allows not only to increase humidity in a grow box, but also to rid the air in it of harmful microorganisms

How to bring down humidity in a grow box

Problems with over-humidification do not occur often. The use of heaters and UV lamps dries the air. Nevertheless, if there is a constant need to reduce humidity, it is recommended to use household dehumidifiers. They are usually compact units equipped with an electronic hygrometer.

A ready-made solution

To constantly maintain the microclimate in the grow box in an automatic mode, you can install a special automation system. You can buy it in a store selling equipment for hydroponics. Devices for temperature and humidity control are able to maintain values in the comfort zone, they are usually controlled by a timer, which means that human participation is practically not required.
