Dehumidifiers play a major role in indoor growing. Growing in a closed environment generates an enormous quantity of moisture. If gone untreated, it’s inevitable to try out high relative humidity, dew point condensation, and in many cases mold development. Thereby, grow room dehumidifiers really are a must-have in almost any grow space.
Exactly why do You want a Grow Room Dehumidifier?
Indoor grow rooms are naturally humid, due to the plants’ transpiration process. All plants constantly release water vapor on the air, within their growth process. So, without including humidity control in your environmental control, any grow room will end up very humid. Specially in dense grow rooms with intense lighting, common in cannabis grow rooms.
Unfortunately, moist levels bring about mold development, including botrytis (aka bud rot), and powdery mildew. Of course, mildews can destroy yields reducing the entire quality of your product. When it comes to cannabis, it might even result in products being disqualified for sale or distribution.
But humidity diseases aren’t a possible problem humidity creates. Even without molds, mugginess can make it challenging for plants to formulate.
To be able to ingest and break down nutrients, the plants must transpire. However, high levels of relative humidity help it become difficult, and even impossible to enable them to achieve this. So the vegetation is left in a condition of stress, inhibiting growth and decreasing the overall yield size and quality.
What Should You Consider In choosing a Dehumidifier on your Grow Room?
The most crucial the answer to consider when selecting a dehumidifier on your grow room, is usually to keep your dehumidifier size matches the transpiration rate with your facility.
Determining Your Required Dehumidification Capacity
Matching your moisture removal, with your plants’ transpiration rate, is critical. In case you don’t remove enough water through the air within a given period, humidity could eventually climb up to 100%. So, it’s vital that you consider your maximum transpiration rate, meaning the whenever your plants release one of the most water vapor.
There are numerous factors that decide how much your plants will transpire.
First, is the quantity of plant matter within your grow room. So, the number of plants, along with the level of foliage on each plant. Some growers use leaf area index (LAI) as a metric for this.
Second, could be the conditions inside your growing environment. Temperature and humidity levels have a direct effect on transpiration rates. So you should know about what your optimal conditions are, plus your power to maintain them. Then you’re able to see how much your plants will transpire under these conditions.
Third, may be the height and width of your grow room. A little space, or small grow room, will probably be simpler to treat for humidity, compared to a large one. Both due to amount of plant matter, these kinds of sites the sheer size of the room.
When you gather this information, you can better understand what you’re standing up against, in terms of moisture.
One very important factor, that’s often overlooked, is the design conditions of dehumidifiers. This can be crucial, as the quantity of water extraction really is dependent upon the climate conditions. These conditions are quite normal in indoor grow rooms, so that you can depend on these figures being strongly related your grow.
It’s worth noting that it’s always simpler to remove moisture in higher temperatures and better humidity levels. So, if dehumidifier manufacturers present extraction rates at hotter or higher humid conditions, it won’t be able to reach the same effectivity at ‘abnormal’ amounts.
Simply speaking – dehumidifiers made for colder and drier conditions, tend to be powerful than others made for hotter and more humid conditions.
Note Your Dehumidifier’s Energy Efficiency
Energy is among the biggest expenses in indoor growing. So optimizing your power consumption includes a major impact on your bottom line.
Different dehumidifiers and humidity control systems have different efficiency levels. The best way to compare dehumidifiers, would be to look at the water extraction per kWh. As pointed out, it’s imperative that you compare dehumidifiers under similar conditions, or perhaps you risk getting wildly different results.
Consider Air Distribution and Airflow
Simply removing moisture from your air is simply one aspect of dehumidification. Without powerful fans and proper air distribution, your dehumidifier won’t manage to treat the entire space. Many dehumidifiers neglect to take this factor into consideration, leaving growers with local humidity treatment and creating different conditions in several areas in the grow room.
Molds just have one plant that’s surrounded by mugginess. If they develop, they’re able to spread freely during the entire grow room, infecting more plants. Regardless of whether humidity is kept under control of their area.
So, making certain your dehumidifier reaches all corners of the grow room is vital.
However, there’s another aspect to air distribution you’ll be able to reap the benefits of with a good dehumidifier – air circulation.
When all vegetation is grown within the identical conditions, you ensure flower consistency and high quality, no matter where you determine your plants.
This is a great addition, as every grow room needs fans anyway. Airflow is vital in stimulating plants and dispersing humid microclimates that may undermine even reliable humidity control.
So, employing a dehumidifier having a well-designed airflow concept can reduce your requirement for additional fans while improving your air distribution.
Dehumidifier Placement Options
Grow room space is precious and costly. So, a content article of equipment or machinery must be as compact as you can, without compromising capacity. A compact 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 most crucial benefit a dehumidifier provides is energy savings. By controlling humidity, utilizing a dedicated and efficient dehumidifier, you are able to drastically lessen your air conditioning equipment or HVAC usage. It releases your temperature controllers to manipulate temperature, without relying on them to help remove moisture. Tweaking your protocol like this can save around 50% on energy!
