Plants have always been a sign of relaxation. Obviously, they don’t naturally belong to any room. As a result, we may have to manage the humidity level at home sometimes to create a healthy environment for the plant. From changing the fan speeds to covering young plants with transparent glasses or plastics, there are some straightforward ways to do so.
How to Increase Humidity in Grow Tent
Nothing is more horrible than watching your lovable plants drying out. Your plants need regular lookouts and maintenance to provide the desired output and glance. If you are a grower, humidity is one of the most important aspects to know about properly.
Grow Tent Humidity
To growers, humidity is more than just the amount of water vapor in the air. The higher the grow tent humidity percentage is, the more water vapors take place and the moister the grow tent feels.
Humidity rises in a place where brightness and irrigation are high, and air ventilation and temperature are low. When there’s a dry atmosphere, a water vapor loss is created.
Growing plants are then burdened with the extra pressure they apply to the roots to absorb that water humidity loss. This leads to plant dehydration and the closing of the stomata. So, maintaining a needed amount of humidity is very much needed.
The Signs of Low Humidity
How will you know that humidity is the problem? Well, if it matches the cases low humidity offers, you should understand it’s the concern. If you feel that your plant is getting weaker day by day and is not growing enough, start noticing. The tip of the leaves of your plants may be burnt. Your plants may consume water instantly after watering and take in excessive amounts each time.
Points to Consider
Before you jump into the ways or guides of increasing tent humidity, there are a few things you need to consider.
Accurate Humidity level
The level of humidity needed for a plant’s growth is not constant. It depends on the growth phase and the plant itself. Infant plants need the highest amount of humidity as that’s the time where they develop roots.
Seedlings generally need 70%-75% humidity, whereas vegging plants need 50%-70% percent of humidity. When the plants come to a satisfying growth or the flowering stage, 40%-50% humidity is okay. In times of harvesting, 35%-40% humidity is needed to prevent molds.
Grow Tent size
The amount of humidity also depends on your grow tent size. It is said that relative humidity should never fall by 20% and never increase more than 75%. For a 4×4 grow tent, a minimum of 40% humidity will be enough but for a 5×5 grow tent, you have to keep at least 65% humidity. So the bigger your tent is, the higher the humidity should be.
As humidity depends on the temperature, you have to know about the accurate temperature levels as well. As an indoor grower, it’s never a loss to invest in an electronic thermometer or a hygrometer.
Infant plants or seedlings require 74-78 degrees Fahrenheit temperature, whereas vegging plants prefer 70-78 degrees Fahrenheit. Flowering plants need 75-88 degrees Fahrenheit and harvesting plants prefer 65-74 degrees Fahrenheit.
How to Raise Humidity in Grow Tent for Drying?
Raising humidity in grow tents is not something you should be tensed for. You can raise the humidity in tents without any expenses and with expenses as well. Here are some of the ways listed below.
Remove The Lights Quickly
Lights increase temperature, and as said before, increased temperature causes decreased humidity. So get rid of the fluorescent lights or any other light added to the tent. Usually, a grow tent has multiple lights. So removing half of them may help you a lot. However, ensure that your plants don’t fall in total darkness and get enough light.
Control The Fan Speed to Control Humidity in a Grow Tent
People usually leave their fans at moderate speeds. But it may not be suitable for different stages of plants. The higher speed does two things in the tent: it helps the air dry out faster, and it doesn’t let the vapor sit on the leaves. This results in low humidity. So it’s better to keep the fan at its minimum speed to increase the humidity. Extra Evaporated Water
You can also put some wet things in the tent to add more evaporated water. For example, you can keep several wet sponges or a big wet towel beside the plant to increase humidity. It will be better to keep the sponges near the tent fans or the air vents.
Sponges are preferred as they dry out faster. It will be better to place a water bowl inside and put the sponges in it. You can place only a bowl full of water, but it takes more time to increase the humidity than the other two. In the case of water towels, two towels will be enough to help a 4×4 grow tent. However, place them so that they don’t hamper the airflow.
Manage AC Settings
Air conditioners are a great source to increase the humidity instantly. If your air conditioner can’t cool down the tent, it won’t be possible to raise the humidity level. So check out the temperature range and keep your ac at its lower range. It will build humidity inside the tent very quickly.
Placing larger plants beside your dehydrated plant is a very natural and easy way to increase humidity. Larger plants have more stomata. So when you place larger plants besides, they’ll release more vapors following evapotranspiration and increase the humidity levels. But remember, none of the plants should be in their flowering stage. If one of them is, you should avoid this trick.
Watering is the easiest and most followed way to increase the humidity of the plants. If your plants start to beg for water, water them more than usual. Water them in short intervals. You can use a spray bottle as well. Watering with spray bottles will help in an even distribution.
Cover The Plants
You can put the plants inside transparent glasses or cover them in plastic for some time. You can use bell cloches as well. Cloches are referred to as domes that help regulate the temperature and moisture levels around various plants. If you use plastic, don’t forget to put some tiny holes in it to allow respiration. Usually, this is required in emergency cases mostly.
If the above ways fail, maybe you need to invest some money in this case now. There are some products available in the market that help raise the humidity of the plants at your desired rate. Here is the list.
Set Your Own Propagation
For this, you’ll need an adjustable extractor and a built-in thermostat. This extractor pulls out the air and controls temperature. To install this, place a bucket full of water on top of the tent. This water will be brought into your humidifier through a hosepipe.
Use A Grow Tent Humidifier
Installing a perfect grow tent humidifier in your grow tent is the most useful investment you could have made for your plants. Depending on the size of your grow tent, you can control the humidity level of your grow tent humidifier. If your grow tent consists of both top and bottom self, try to install the humidifier in the bottom part. It would be best if you purchase a humidifier with a built-in humidistat.
Decide The Floor Soil
It may sound hard, but it’s a very effective way. Sometimes the soil becomes the culprit of bringing down the humidity level. You should choose soil with a huge water holding capacity and build a large water surface area.
In terms of holding water, clay works the best. Then comes silt, and at last, comes sand. However, using a floor of full clay is not suggested. It will be best if you use a mix of clay and silt.
Consider The Season
When it comes to humidity, the season always matters. The tricks of raising humidity may not be the same for all seasons. According to the season, you have to decide the level and the amount.
Humidity is high in summer. You may not need to follow extreme methods in this season to raise the humidity. Dehydration problem occurs less this time. Ensure that your tent temperature remains 18-22 degrees Celsius. The humidity will adjust on its own then. Even if it doesn’t, just regular watering and some simple tricks will do the work for you.
Winter is the roughest season, and this can be the season of your nightmares. So act really carefully towards your plants at this time. In this season, please spend some money and buy a humidifier. Normal methods may not satisfy you this time.
Spring is quite unpredictable in terms of humidity. You should keep all the points in your head at this time because any of them can be required. Just follow the trick that will suit the best according to the temperature and the humidity level.
Look Out the Rise
As mentioned before, low humidity is not good for your plants. But too much humidity is also harmful. Too much humidity can kill your plants as well. Too high humidity can increase the chance of infections and disease levels.
It will create a better environment for mold and bacteria growth. Your plants will get suffocated, and the efficiency of nutrient intake will decrease. So this is the part where you should get tensed. Look out if you’re following just the needed amount of overdoing.
Q: What is the distinction between a humidifier and a vaporizer?
Ans: A humidifier discharges a cool drizzle by physically dropping mini droplets into the airflow. On the other hand, a vaporizer heats water and discharges steam. A humidifier is recommended in grow places.
Q: What size humidifier is ideal for a 4×4 grow tent?
Ans: To keep 40% humidity in a 4×4 grow tent, you should go for a humidifier that has a capacity of 1-gallon water.
Always keep a check on the temperature and maintain the abundance of airflow. The ways and tricks mentioned above are very cost-effective and grower-friendly. So don’t let your plants suffer from dehydration. Hopefully, these guidelines will help you in achieving the perfect surroundings for your plants.
