Dehumidifiers play an important role in indoor growing. Growing in different closed environment generates a huge level of moisture. If gone untreated, it’s inevitable to have high relative humidity, dew point condensation, as well as mold development. Therefore, grow room dehumidifiers really are a must-have in almost any grow space.
Exactly why do You Need a Grow Room Dehumidifier?
Indoor grow rooms are naturally humid, as a result of plants’ transpiration process. All plants constantly release water vapor towards the air, within their growth process. So, without including humidity control as part of your environmental control, any grow room can be very humid. Specifically in dense grow rooms with intense lighting, common in cannabis grow rooms.
Unfortunately, high humidity levels bring about mold development, such as botrytis (aka bud rot), and powdery mildew. Naturally, mildews can destroy yields minimizing the complete quality of your product. In the case of cannabis, it may even lead to products being disqualified for sale or distribution.
But humidity diseases aren’t a possible problem humidity creates. Even without molds, mugginess helps it be a hardship on plants to produce.
To be able to take in and stop working nutrients, the plants must transpire. However, high degrees of relative humidity help it become difficult, and even impossible for them to achieve this. Therefore the vegetation is left in a condition of stress, inhibiting growth and decreasing the overall yield size and quality.
What Should You Consider When Choosing a Dehumidifier for Your Grow Room?
The main factor to consider when selecting a dehumidifier on your grow room, is always to be sure that your dehumidifier size matches the transpiration rate within your facility.
Determining Your Required Dehumidification Capacity
Matching your moisture removal, with your plants’ transpiration rate, is important. Should you don’t remove enough water from the air in just a given period, humidity may ultimately climb to 100%. So, it’s imperative that you consider your maximum transpiration rate, meaning the whenever your plants release one of the most water vapor.
There are lots of factors that figure out how much your plants will transpire.
First, is the level of plant matter with your grow room. So, the quantity of plants, as well as the amount of foliage on each plant. Some growers use leaf area index (LAI) as being a metric just for this.
Second, may be the climate within your growing environment. Temperature and humidity levels have a direct impact on transpiration rates. Which means you should know what your optimal the weather is, plus your ability to maintain them. After that you can determine how much your plants will transpire under these conditions.
Third, could be the size of your grow room. A smaller space, or small grow room, will probably be simpler to treat for humidity, compared to a large one. Both due to the level of plant matter, and due to the sheer size the space.
After you gather doing this information, you can better determine what you’re taking a stand against, in terms of moisture.
One key element, that’s often overlooked, will be the design conditions of numerous dehumidifiers. That is crucial, as the level of water extraction really is dependent upon the weather conditions. These conditions are quite normal in indoor grow rooms, in order to count on these figures being strongly related your grow.
It’s important to note that it’s always better to remove moisture in higher temperatures and better humidity levels. So, if dehumidifier manufacturers present extraction rates at hotter or more humid conditions, it won’t manage to achieve the same effectivity at lower levels.
To put it briefly – dehumidifiers made for colder and drier conditions, tend to be more powerful compared to those designed for hotter plus much more humid conditions.
Note Your Dehumidifier’s Energy Efficiency
Energy is one of the biggest expenses in indoor growing. So optimizing your time consumption carries a major impact on your bottom line.
Different dehumidifiers and humidity control systems have different efficiency levels. The best way to compare dehumidifiers, is always to look at the water extraction per kWh. As mentioned above, it’s crucial that you compare dehumidifiers under similar conditions, or you risk getting wildly spun sentences.
Consider Air Distribution and Airflow
Simply removing moisture in the air is just one facet of dehumidification. Without powerful fans and proper air distribution, your dehumidifier won’t be capable of treat the entire space. Many dehumidifiers fail to take this factor into consideration, leaving growers with local humidity treatment and creating different conditions in numerous areas in the grow room.
Molds only need one plant that’s in the middle of moist. When they develop, they’re able to spread freely through the entire grow room, infecting more plants. Even though humidity is kept in order within their area.
So, ensuring that your dehumidifier reaches all corners of the grow room is vital.
However, there’s another aspect to air distribution you are able to benefit from with a dehumidifier – air flow.
When all plants are grown beneath the exact same conditions, you ensure flower consistency and high quality, no matter where you add your plants.
This is a great addition, as every grow room needs fans anyway. Airflow is important in stimulating plants and dispersing humid microclimates that may undermine even reliable humidity control.
So, employing a dehumidifier using a well-designed airflow concept can help to eliminate your requirement for additional fans while giving you better air distribution.
Dehumidifier Placement Options
Grow room space counts and costly. So, any piece of kit or machinery needs to be as compact as possible, without compromising capacity. A compressed dehumidifier can fit snuggly relating to the plants. Nevertheless, you might also want dynamic placement options, to make sure you can optimize your grow space.
However, the main benefit a dehumidifier provides is energy savings. By controlling humidity, utilizing a dedicated and efficient dehumidifier, it is possible to drastically decrease your ac or HVAC usage. It loosens your temperature controllers to manipulate temperature, without depending upon these to help remove moisture. Tweaking your protocol this way can help to conserve around 50% on energy!
