If you’re interested in cultivating plants, especially cannabis, in an indoor setting, then you will need grow tents that are adequate in size. However, there is more to the process than just purchasing some grow tents. You need the right tools, and the conditions have to be right in order to have a successful cultivation. Different factors contribute to the plant’s successful growth; one of these factors includes humidity, which is why you will need the best dehumidifier for your grow tent.
If your grow tent’s humidity level is too low or too high, the plants in your grow tent will be affected negatively. It may increase the growth chances of mold and mildew on your plants. It could also make them prone to different types of diseases.
However, there are some factors that need to be considered before you can purchase the best dehumidifier. First of all, let us talk about the benefits of having a dehumidifier in your grow tent.
BENEFITS OF USING A DEHUMIDIFIER IN A GROW ROOM
Different benefits come with using a dehumidifier I a grow room. Still, one of the most important benefits it has is its ability to regulate the humidity levels in the grow tent. One of the most important things to know about growing cannabis is the fact that it requires a regular intake of gallons of water. If the moisture content in a grow tent is high, the leaves of the cannabis plant tend to absorb the moisture from the area around them. However, if the moisture in a grow box is low, the plants will absorb water through their roots.
That is why it is important to have the best dehumidifier in your grow tent to provide you with the best moisture level to help your plants thrive. Maintaining the right humidity levels in your grow tent allows your cannabis plants to develop properly; it allows our plants to turn out healthy, strong, and leafy. Apart from the benefits you get from using the best dehumidifier to control your grow room’s humidity, it also helps you prevent issues such as leaf rot, mildew, and bud rot.
One of the most common issues with growing cannabis in an environment with high moisture is the development of white powdery mildew. It is a fungal disease that is difficult to deal with because cannabis plants thrive best in humid areas. However, if you have a good grow room dehumidifier and proper air flow in your grow tent, you’ll be able to prevent the fungus’ growth and keep your plants safe.
Growers that have a poor environment inside their grow tent tend to suffer the development of bud rot. The main problem with bud rot is that it’s hard to notice. You may harvest your cannabis thinking that your plants are completely healthy only to find out that you’ve got an infested batch with moldy buds. Ensuring that you purchase the best dehumidifier for your grow room allows you to get the best results and prevent frustration.
WHAT SIZE OF DEHUMIDIFIER TO USE IN YOUR GROW TENT?
When shopping for the best grow room dehumidifier, one of the important factors to consider is the size that will work best for your grow tent. If your grow tent is large, you will need a large dehumidifier. If not, the tank of the humidifier will get full easily, and you will need to empty it frequently. The best way to choose the right size of dehumidifier for your grow room is by getting familiar with the calculator for grow room dehumidifiers. There are different factors that determine the size of the dehumidifier you will get; these factors include the amount of moisture present in the grow room and the number of plants you have. Another important factor is the daily watering of the plant because it will let you know how much moisture needs to be removed daily.
HOW TO DEHUMIDIFY A ROOM
You already know that using a dehumidifier is a great way to dehumidify your grow room; however, there are other ways that you can use to deal with humidity in order to ensure that your marijuana has the best environment to grow. Another way to deal with humidity is by having proper ventilation in your grow room, ensure that the ventilation is not excessive compared to what the plants need. To reduce the amount of moisture in the air, you just have to reduce the ventilation.
To reduce humidity, you could also use a space heater. But you have to be careful while using a space heater, especially during summer; if not, it might burn the plants. Another way to control humidity in your grow room is by sealing and insulating the grow room; you can keep moisture at its minimum without using a dehumidifier.
WHERE TO PLACE A DEHUMIDIFIER IN YOUR GROW ROOM
Various factors affect how effective a dehumidifier can be, but one of the most vital aspects is the dehumidifier’s placement. Placing it at the right position will make sure that it is able to take out the excess moisture so that it doesn’t affect the plants.
If you have just one dehumidifier, you need to put it in a central position where it can work best. The best place to place it is next to or above a grow light; it shouldn’t be too close to the plants. You should also focus on the right spacing for the dehumidifier; however, the spacing depends on the size and capacity of the dehumidifier you own.
There are three factors you need to consider when placing your dehumidifier; they include redundancy, efficiency, and accessibility. Efficiency means that the dehumidifier needs to be placed in a way that properly covers your plants without wasting energy.
Another aspect to consider is redundancy. Maintaining the moisture in your grow area is important in cannabis cultivation; thus, you have to ensure that if one dehumidifier stops working, you have a second dehumidifier to pick up the slack and deal with the humidity without disturbing the health of the crop.
The final step is making sure that the dehumidifier is accessible to you at all times because they need to be checked on regularly after being installed.
WHAT IS THE RIGHT HUMIDITY LEVEL DURING FLOWERING?
Humidity can be explained as the amount of water vapor that is present in the air at a particular time. There are different ways to measure moisture, such as absolute, relative, and specific. You need to be more concerned with RH (relative humidity) in your grow tent for growers.
Relative humidity means measuring the amount of moisture in the air compared to the maximum capacity of water present in the air at a particular temperature. During the flowering stage of cannabis, the best RH for your grow tent should be around 40 to 50 percent. If your goal is to produce more resin, then you can use a dehumidifier to reduce the moisture to about 40 to 45 percent during the final two weeks of flowering.
HOW TO USE A DEHYDRATOR TO DRY CANNABIS
We know that a dehumidifier can be used to speed up the drying process of cannabis, but you could also use a dehydrator to dry cannabis. A dehydrator is another piece of equipment that you might consider getting, especially if you are serious about growing cannabis. The process of using a dehydrator to dry cannabis includes trimming the bud and ensuring it is dirt free, put it in a brown bag, and place it in the dehydrator.
However, the majority of growers do not like this idea. They believe that the best way to dry cannabis is by hanging it in a room with the right conditions and waiting for it to dry on its own. They say that you will get the best results this way.
IS IT EXPENSIVE TO RUN A DEHUMIDIFIER FOR A GROW ROOM?
It is important that you know how much it costs to run a dehumidifier for a grow room, most especially because you might need more than one, depending on the size of your grow room. A basic sized dehumidifier uses around 280 Watts per hour.
Assuming the power rate in your area is 15 cents per kW, then running a dehumidifier will cost you about 4.2 cents in power per every hour you use the dehumidifier. If you use your dehumidifier for 24 hours, you would be spending about a dollar per 24 hours; that will be $365 per year on each dehumidifier. That is why we advise that you get an Energy certified dehumidifier because they cost less to use, and it will save you money in the long run.
We have decided to help you perform the hard part of the task and look at some of the best grow tent dehumidifiers available on the market. All you have to do is look through and choose what works best for your needs.
