When it comes to maintaining healthy humidity levels in greenhouses, nurseries, or indoor grow rooms, many factors come into play. Excess moisture can lead to mold and mildew growth, and other various plant diseases. On the flip side, too low humidity levels can’t stunt a plant’s growth. The easiest and most consistent way of regulating humidity is with a dehumidifier.

It’s no secret that plants need the right amount of water, nutrients, and sunlight to survive and thrive. But did you know that humidity levels can actually determine how much water your plants will absorb? Furthermore, because plants attain most of their nutrients from water, controlling humidity levels allows you to control your plant’s nutrient intake.

The best dehumidifiers for grow rooms, nurseries, and greenhouses should have some type of automatic humidity controls, allowing you to set your desired humidity levels and control them when necessary. Energy-efficient operation can also make a real difference when you’re running a dehumidifier for days or weeks on end. Ducting and continuous drainage are also important, especially when you’re growing on a larger scale.

Most professional growers recommend higher humidity levels during the initial growing stages for optimal plant growth. However, during the rest of the growing cycle, lower humidity levels are often the norm. It’s not unheard of to employ a humidifier for the beginning stages of growing and a dehumidifier for the later stages. Both are extremely useful and often necessary for healthy indoor plant growth.

It’s also highly beneficial to ensure proper air circulation and ventilation when growing plants indoors. When air is efficiently circulated and humidity levels are healthy, mold, mildew, and bud rot are more easily avoided. In addition, proper ventilation and air circulation helps to regulate temperatures and can help better distribute CO2, which tends to naturally settle at floor level.

Indoor growing can often require precise and accurate humidity levels. For this reason, we highly recommend purchasing a dehumidifier with a built-in humidity gauge. If that’s not an option, then a separate digital humidity gauge is your next best bet. These tools are essential when you need to pinpoint humidity levels. Some even come wireless and with remotes for easier operation.

Depending on where you live, a humidifier may be needed more often than not. Dryer climates such as out west will often require higher humidity levels for healthy plant growth. The most effective way of achieving higher humidity levels is by investing in a humidifier. An ideal grow room, or greenhouse humidifier will have a large water tank capacity and some type of automatic humidity control or humidistat.

Here at Achoo, we know indoor growing is not a one size fits all operation. A grow room, greenhouse, or indoor nursery can be as big or small as you need or want. Either way, no matter how big you’re grow is, we hope these tools, tips, and tricks help bring you that much closer to achieving your indoor growing dreams!
