Grow Tent

Being an indoor gardener, you must be aware of the challenges to keep your garden maintained and in tip-top position. You may already know that apart from temperature regulation and air conditioning, humidity is another factor that can never be ignored. Immoderate levels of humidity can affect the output of your produce.

Therefore, you need to keep it in check by making sure to take the necessary steps required to do so. We understand that sometimes it can be pretty hectic and confusing to maintain that average humidity level even for experienced gardeners. However, you need not worry as we shall guide you on how to control humidity in grow tent with few essential tips and steps.

1. Temperature Regulation

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

Air conditioning is the right answer for air regulation. However, you need to be wary of oversize air conditioning systems turned on at full speed that can cause irregular temperature fluctuations. Similarly, too small ACs are also not recommended.

2. Allow Ventilation

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

A right way for ventilation is to rely on both exhaust and floor fans. These fans will pull the air and circulate it while creating a consistent environment and even levels of humidity 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, the extra standing water can significantly increase the humidity level inside the grow tent.

Therefore, make sure to have a proper drainage system that allows the extra water to escape. Also, don't forget 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 going to and investing in humidifiers and dehumidifiers.

It is worth-while to mention that a high humidity level is good for the plants as they need suitable levels of waters for normal functioning. That helps the plants to conserve the much-needed moisture. However, be wary that you should only look for the best humidifier for grow tent. That is because of lower-end humidifiers with underwhelming performance can do more harm than good. Also, don't leave the humidifier open for more extended periods if not needed. 

As the name suggests a dehumidifier is helpful in too humid environments by eliminating the excess of moisture in the grow tent. However, make sure to invest in the best dehumidifier for grow tent since it is worth the outcome of your produce. Some examples of the quality dehumidifier are Frigidaire and Eva-dry.


As a gardener, you need to be vigilant of the humidity and temperature levels of your grow room. A very high or deficient humidity level does not encourage average plant growth. Therefore, to yield the best results, make sure to follow the tips stated above. Also, look for the best humidifiers and dehumidifiers that keep your grow room a pleasant breeding ground for the plants.
