Grow Rooms with Dehumidifiers

Why HEMP Grow Rooms with Dehumidifiers? If you know anything about growing hemp, you’re well aware that adequate lighting, nutrients, and ventilation are key aspects of cultivating this profitable plant. However, many growers overlook a key factor that can make or break a grow operation: humidity. If the humidity in your growing environment is too high or too low, your plants will suffer, and in this guide, we’ll explain why controlling the humidity in your grow room is so important and cover the benefits of investing in a growing environment with built-in humidity controls.


The Importance of Controlling Grow Room Humidity

While hemp can grow pretty much anywhere, the various strains of hemp sativa are all essentially tropical plants, which means that they require warm, humid climates to reach their full potential. However, these environmental constraints come with their share of challenges; if the humidity in your grow room is too high, you could lose some or all of your crop to nightmare situations like mold infestations.

Controlling the humidity in your grow room isn’t all about siphoning off excess air moisture when it reaches uncomfortable levels. If your lights are bright and powerful enough, you might need to reintroduce humidity into your grow room at various points throughout the day. While some growers choose to take care of this task by spraying their plants with water, this method is inefficient when compared to the benefits of using industrial humidifiers to add extra humidity when it’s needed.

A grow room that’s too humid or not humid enough isn’t good for your plants, but it also isn’t good for the workers who are tasked with taking care of your babies. Grow operations with too much humidity can make workers feel uncomfortable or even sick; when combined with bright, hot lights, it’s possible to come down with heat exhaustion if you spend too much time in a humid grow room.

Factors That Affect Grow Room Humidity

Here are a few of the variables that can raise or lower the humidity in your grow room:

1. Lights

If you’re a traditionalist, your grow lights can significantly reduce the humidity in your grow room. Until recently, practically all hemp horticulturalists used high-pressure sodium (HPS) and metal halide (MH) bulbs to grow hemp, and both of these types of bulbs let off huge amounts of heat.

HPS bulbs are used in the flowering stage due to the warm light spectrum that they produce, and MH bulbs are used in vegetation since they produce whiter light. If you’re using either of these bulb types in your grow room, you’ll need to account for the drying effect that they cause, but if you keep up with the times, you might have already ditched these short-lived and relatively dangerous bulbs in favor of the wave of the future.

In recent years, light-emitting diode (LED) lights have become increasingly popular in the hemp growing community. These grow lights produce hardly any heat, but they provide excellent full-spectrum lighting that’s fully programmable.

2. Fans

The fans in your grow room can reduce humidity by circulating air throughout your grow room. While the humidity reduction that your fans cause is usually minimal, it’s still important to keep this factor in mind.

3. Spraying

If you spray your plants to keep them moist or ward off pests, you’re adding to the humidity in your room whenever you squeeze the trigger on your spray bottle. Keep track of the amount of water you spray in your room to ensure that you don’t raise the humidity too high.

4. Watering Cycles

Right after you water your plants, the humidity in your grow room will increase substantially. While this humidity increase dissipates over time, you might want to schedule your waterings to coincide with the driest periods in your grow room.

5. Day and Night Cycles

When the lights are on during “daytime” in your grow room, the environment in your room naturally decreases in humidity and increases in temperature. After the lights in your grow room go out for the night, the opposite occurs; humidity can reach dangerous levels and temperatures can drop too low without lights to burn off the excess moisture.

Even if your grow room is equipped with cutting-edge LED lights, you’ll need to program your room to keep humidity at a steady level whether your plants are currently “awake” or “sleeping.” Consistency is key in hemp cultivation, and your plants will be happier if they’re exposed to an environment that changes as little as possible.

What Happens if Your Humidity Is Off?

If you don’t keep your grow room’s humidity levels steady, your plants will suffer. Hemp plants like to stay moisturized; if your grow room isn’t humid enough, your leaves and buds might start to dry out, and in extreme scenarios, your plants could even start becoming fire hazards.

When the humidity in your grow room is too high, however, you can face even worse consequences. Pests thrive in humid environments, and excess humidity in your grow room can even cause a grower’s worst nightmare: mold.

There’s nothing worse than going into your grow room one morning only to be confronted by blotches of greenish mold on each of your plants. Even a small mold infestation can ruin an entire crop, and the discovery of moldy plants may even force you to completely gut your grow operation and start over.
