Being an indoor gardener, you must know the challenges of maintaining your garden in tip-top position. You may already know that apart from temperature regulation and air conditioning, humidity is another factor that must always be addressed. Immoderate levels of humidity can affect the output of your produce.

Therefore, you need to keep it in check by taking the necessary steps to do so. However, you need not worry; we shall guide you on controlling humidity in grow tent with a few essential tips and actions.

1. Temperature Regulation

Plants need time and consistency to adapt to a specific environment and temperature. The adverse effects of intense heat on plants are no mystery to us. Therefore, you need to maintain the average temperature while keeping it consistent.

Air conditioning is the correct answer for air regulation. However, you must be wary of large air conditioning systems turned on at full speed, which can cause irregular temperature fluctuations. Similarly, more ACs should be recommended.

2. Allow Ventilation

Air circulation is vital for the average growth of plants. Ventilation will allow the humidity levels to lower and maintain the air pressure while evenly circulating the air all over the room. The carbon dioxide is In this air essential for plant growth.

The proper way for Ventilation is to rely on exhaust and floor fans. These fans will pull the air and circulate it while creating a consistent environment and even humidity levels with balanced CO2 distribution. As a result, your plants get the most suitable environment required for healthy growth.

3. Drain-out Still Water

An excellent way to control humidity in a grow tent is to have an efficient drainage system that can effectively manage even water. In the case of overwatering, extra standing water can significantly increase the humidity inside the grow tent.

Therefore, ensure a proper drainage system that allows the extra water to escape. Also, remember to cover up any water reservoir to prevent further increase in humidity in the grow tent. In this regard, it is important to not overwater the plants, as soggy soil can also add to the humidity level.

4. Keep the Grow Room Sealed

A properly sealed grow room prevents intrusion of external factors such as wind, cold, heat, or dust. Foam insulation is an excellent way to do so.

5. Using Humidifier and Dehumidifier

The most obvious and effective way of achieving the desired humidity level is by investing in humidifiers and dehumidifiers
