Why Is Humidity Important In A Grow Room?

Before you even start creating that humidity, you need to understand why your grow room needs it. Plants need humidity for proper growth; they have different water intake needs at every stage of their growth. As humidity changes in your grow room, so does the need for water in your plants.

Your plants will start pulling less water from the roots if there is high ambient in the humidity of your grow room. In the case, the leaves become main vessels for moisture absorption from the environment. And if humidity is low, plants take in a large amount of water through the roots.

Your sprout will require varying drinking needs from time to time and humidity is at the center of it all. The plants will need nutrients to survive and grow well, which depends largely on the level of humidity. Controlling humidity in the grow room, therefore, becomes a task you cannot look away from.

You need to encourage health and green buds along with proper growth. From the time your plants start sprouting, it is vital to manipulate the humidity in the growing areas. Your plants will start to produce large amounts of resin which in turn prevents mould attack.

Too much humidity is the worst nightmare you will ever have to deal with. It can cause buds to rot or bring dense mold on young plants. Apart from that, too much humidity will prevent your plants from inhaling CO2, something they need.

Low humidity on the other hand cause VPD/ high vapor pressure deficiency. Leaves of any plants are usually moisturized inside, which is all good for them. But then, the pores on the leaves expose the plant to losing moisture, yet they are necessary for the gaseous exchange.

Plants will suck in more moisture when the environment outside is too dry. They will be fighting to keep alive. As if that is not enough, dry humidity increases chances of harmful bacteria attacking the plant.

So How Do You Control Humidity?

If you are new to indoor gardening, like other beginners, you may not understand the impacts of controlling your climate. The simplest threat is, all your efforts will go in vain!

Controlling the climate of a grow room should be top on the to-do list of any fresher. Here are some of the most basic steps you can use to achieve this.

• Proper Lighting Set-Up

Light is very important for plants. And when it comes to running a grow room, you don’t want to take any chances with it. It can be a crucial factor in determining your success.

Too much light increases heat in your grow room, which raises the humidity in the room. And too little light may lower humidity. You need to carefully think about the lighting system you are going to put in place.

We recommend that you use an LED grow light created with proper specifications. Others recommend using metal halide lights as well as HPS lighting systems.


• Keep The Temperature Right

In a normal situation, grow room temperature lies with the 20 degrees range because there are always lights to add on a boost. The temperature is just right to keep your plants from freezing. But too high temperature will fry your plants as well.

As mentioned above, the leaves are always moisturized inside. When trying to control the lights, be careful with the cooling system.

For those who are growing the plants as a hobby, window AC is enough to cool the room. Sometimes, using simple AC is however not enough when you want to scale up. For a high scale grow-room, consider a system like central air controlling.


• Keep a Continuous Flow of Air in the Whole Room

The room needs air, and you need to ensure a continuous movement. There are two important reasons you need to keep the air right. One because you want to keep those molds out and second to help plants build a strong stem and branches.

Plants need transpiration for gaseous exchange. Plants suck up water through the roots and eliminate it through the leaves by evaporation.

You need proper air circulation to control relative humidity in your grow room. Oscillating fans are well enough, and they can help in providing continuity in air circulation.


• Have a Control Measure

The other best way to ensure humidity in your grow-room is to use a handheld sensor to control it. The sensors usually give accuracy up to 5%.

If you are running a sizeable indoor gardening operation, you will need an electronic gardening system. There are several choices in electronic humidifiers that have both sensors and recorders.

Many people start forgetting about humidity when they move to larger growing operations. And it brings in confusion about the moisture needs of the plants. For small places, you can catch a simple residential dehumidifier from a hardware store.


• Control CO2

Use ventilation as the most basic means to control humidity. It makes it easy to control humidity by controlling the amount of air inside the room.

Using an exhaust fan is probably the best solution. Many people use this by adding an intake hole to make it more functional. You can also make it automatic by using a hygrometer to power the fan.

Plants need fresh CO2 constantly for photosynthesis. Lack of ventilation can cause a rise in humidity, and you don’t want that.

Well, there you have it, the best way to create and control humidity in your grow room. As you can see, it is not very difficult, but you have to be careful enough to achieve efficiency.
