Dehumidifiers play an important role in indoor growing. Growing in almost any closed environment generates a tremendous volume of moisture. If gone untreated, it’s inevitable to see high relative humidity, dew point condensation, and in many cases mold development. Therefore, grow room dehumidifiers can be a must-have in a grow space.
How come You’ll need a Grow Room Dehumidifier?
Indoor grow rooms are naturally humid, due to plants’ transpiration process. All plants constantly release water vapor to the air, within their growth process. So, without including humidity control as part of your environmental control, any grow room will become very humid. Especially in dense grow rooms with intense lighting, common in cannabis grow rooms.
Unfortunately, high humidity levels lead to mold development, such as botrytis (aka bud rot), and powdery mildew. Of course, mildews can destroy yields minimizing the general quality of one’s product. In the case of cannabis, it might even bring about products being disqualified available or distribution.
But humidity diseases aren’t the only issue humidity creates. Even without molds, moist causes it to be hard for plants to formulate.
So that you can take in and break down nutrients, the plants must transpire. However, high numbers of relative humidity make it difficult, or perhaps impossible to allow them to do this. Hence the plants are left in a condition of stress, inhibiting growth and decreasing the overall yield size and quality.
What When you Consider When selecting a Dehumidifier to your Grow Room?
The most important factor to consider when choosing a dehumidifier to your grow room, is to be sure that your dehumidifier size matches the transpiration rate inside your facility.
Determining Your Required Dehumidification Capacity
Matching your moisture removal, together with your plants’ transpiration rate, is very important. In case you don’t remove enough water through the air in a given period, humidity will ultimately climb up to 100%. So, it’s important to consider your maximum transpiration rate, meaning the time whenever your plants release one of the most water vapor.
There are many factors that decide how much your plants will transpire.
First, may be the amount of plant matter within your grow room. So, the quantity of plants, as well as the level of foliage on each plant. Some growers use leaf area index (LAI) like a metric just for this.
Second, may be the climatic conditions in your growing environment. Temperature and humidity levels have a direct impact on transpiration rates. Which means you should know about what your optimal the weather is, plus your capability to maintain them. Then you’re able to figure out how much your plants will transpire under these conditions.
Third, could be the sized your grow room. A small space, or small grow room, is going to be simpler to treat for humidity, than the usual large one. Both because of the quantity of plant matter, and due to the sheer sized the space.
As soon as you gather doing this information, you are able to better understand what you’re standing up against, when it comes to moisture.
One very important factor, that’s often overlooked, will be the design conditions of numerous dehumidifiers. This can be crucial, as the quantity of water extraction really is dependent upon the weather conditions. These conditions are common in indoor grow rooms, to help you depend on these figures being highly relevant to your grow.
It’s important to note that it’s always much easier to remove moisture in higher temperatures and better humidity levels. So, if dehumidifier manufacturers present extraction rates at hotter or even more humid conditions, it won’t manage to achieve the same effectivity at lower levels.
Simply speaking – dehumidifiers suitable for colder and drier conditions, tend to be more powerful than these created for hotter and more humid conditions.
Note Your Dehumidifier’s Energy Efficiency
Energy is probably the biggest expenses in indoor growing. So optimizing your power consumption has a major influence on your net profit.
Different dehumidifiers and humidity control systems have different efficiency levels. The easiest method to compare dehumidifiers, is always to measure the water extraction per kWh. As mentioned above, it’s imperative that you compare dehumidifiers under similar conditions, or perhaps you risk getting wildly spun sentences.
Consider Air Distribution and Airflow
Simply removing moisture in the air is simply one facet of dehumidification. Without powerful fans and proper air distribution, your dehumidifier won’t be capable of treat the entire space. Many dehumidifiers neglect to take this factor into account, leaving growers with local humidity treatment and creating different conditions in several areas inside the grow room.
Molds merely have one plant that’s in the middle of mugginess. When they develop, they can spread freely through the entire grow room, infecting more plants. Regardless of whether humidity is kept in order in their area.
So, making sure your dehumidifier reaches all corners of one’s grow room is critical.
However, there’s another aspect to air distribution it is possible to benefit from with a good dehumidifier – air circulation.
When all plants are grown under the exact same conditions, you ensure flower consistency and high quality, regardless of where you add your plants.
A great addition, as every grow room needs fans anyway. Airflow is very important in stimulating plants and dispersing humid microclimates which could undermine every humidity control.
So, by using a dehumidifier having a well-designed airflow concept is able to reduce your dependence on additional fans while giving you better air distribution.
Dehumidifier Placement Options
Grow room space matters and costly. So, a content article of it technology or machinery ought to be as compact as possible, without compromising capacity. A concise dehumidifier can fit snuggly between plants. However, you could also want dynamic placement options, to be sure you can optimize your grow space.
However, the main benefit a dehumidifier provides is energy savings. By controlling humidity, by using a dedicated and efficient dehumidifier, it is possible to drastically lessen your air conditioning unit or HVAC usage. It frees your temperature controllers to regulate temperature, without relying on the crooks to help remove moisture. Tweaking your protocol this way can help to conserve just as much as 50% on energy!
