Marijuana plants emit an odor especially when these are flowering. The smell of the plant when the buds are there will fill the air with the aromatherapy. The aromas emitted by the cannabis plant might sometimes be overwhelming. It’s a good thing to take the time to study this air circulation and exhaust tutorial for your marijuana grow room as that is one of the ways to ensure the optimal growth and development of cannabis plants.
Plants Need Air
We need to breathe to live and marijuana plants also need air. And enclosed room without open windows or door like those of storage rooms can be stuffy. If a plant is left is an enclosed room, it may survive but it will not thrive. Air is vital to a plants growth, as vital as the air that we breathe.
A marijuana plant has strong aromas. The smell will fill the air of a grow room. If the area is enclosed, the aroma will linger in the air. If you enter it to nurture the plant, it the smell might be overpowering.
It just makes sense to ensure that there is proper air circulation for an indoor area, even if it is just an ordinary room that you use for your home like the kitchen. It is good for you who needs to breath in the oxygen air. It is good for the plant that needs to ‘breathe’ the carbon dioxide in the air. The air that we breathe is made up of 21 percent oxygen. The other 78% is nitrogen. Then there is a small amount of carbon dioxide which is also known as CO2 and other gases.
A grow room requires a ventilation system. This is just as vital as having lights and providing the weed with nutrients. Proper ventilation will maintain the necessary atmospheric conditions – CO2 levels, temperature, and humidity – of the indoor garden. All of these factors contribute to the growth and development of the cannabis plant. When these factors are correct, the plant will have the optimal conditions for accelerated growth.
Plants Love Fresh Air
Many cannabis plants growing in the wild such as the Afghan weed strains that are found at the mountainous region of the Afghanistan-Pakistan border. These plants, like many other weed strains, thrive when there is fresh air.
That kind of fresh mountain air might seem difficult to achieve when one lives in the city that has polluted air. Yet, the wonderful thing about having a grow room is that it is possible to control many factors such as the air circulation through the air quality might not seem right because of the pollution.
Polluted Air
Note that polluted air does have a larger amount of carbon dioxide as in the city, it is typically the fuel that burns from vehicles that contribute to the CO2 levels. This is not to say that polluted air is a good thing but it is not bad for the marijuana plants because these ‘breathe’ carbon dioxide.
Advantages of Proper Air Circulation and Exhaust
When you create the right atmospheric conditions in your grow room, the plants will reward you with a bountiful and beautiful harvest. To nurture a plant that is silent and undemanding required gardening skills like irrigation and defoliation. To care for it by giving it the basic needs such as light and air can make a plant thrive. You don’t want your cultivated cannabis to not do well as it does take a lot of time and effort plus expense to grow a marijuana plant.
If you are ready to set up your grow room to achieve the optimal conditions, you must be ready to spend a little or tackle the tasks by doing it yourself using innovative materials.
Accelerated Growth
When a plant is given the right growing conditions, it will prosper and get to grow at an accelerated rate. The symphony of nature that you create in the grow room to include the ventilation will aid the cannabis strains to grow vigorously. If there is no or limited air circulation, the carbon dioxide in the room is low and that will prevent the plant from growing properly and prospering.
Larger yields
If you have proper ventilation, a plant can give larger yields. When the harvest per plant is larger, it can save you from cultivating another plant. For example, your chosen indica plant yields an average of 500 grams. If the yield can be increased by just a bit, such an additional 100 grams, if you have 4 marijuana plants, you have an extra 400 grams.
Better Yields
When a plant experiences accelerated growth, the buds will be better as these can become bigger and achieve uniformity in size. It is not just ventilation that will make those potent buds achieve maximum potential, it is the harmony of your nurturing care such as defoliation and the other conditions in the grow room. Keep in mind that a quality harvest is a goal – and that means that the buds are nearly the same size and shape, have a healthy color, and other factors that indicate good crop productions.
Humidity and Temperature Control
There is water vapor in the grow room and that has to be dispersed. The air circulation will do the task of dispersing that water vapor. It also works to get rid of hot spots in the area as the heat will be distributed evenly. Aside from the air circulation bringing in the supply of fresh air, it also aids in controlling the humidity. Dispersing and diluting what is in the air is what ventilation does.
Prevention of Common Plant Diseases
There are ideal growing conditions for marijuana plants. If the area is too humid, a plant will be susceptible to mold and mildew, just like what happens in a bathroom.
Prevention of Pests
Stagnant air will make those awful fungus gnats, spider mites, and other creepy crawlies want to turn the grow room into an insect kingdom. If the topsoil is damp, the insects will like to breed on it. When there is good air circulation, the topsoil will be dry and it will discourage the insects to use it as a breeding ground.
Stronger Plants
When the growing conditions are right, a plant will be stronger – yet there is a direct effect to the plant that good air circulation provides The light breeze created in the grow room will make a plant sway slightly. This will strengthen the plant, especially the stem, as it bends, The effect of the wind stress outdoors can be damaging but without wind, it is unnatural. A plant naturally sways because of the wind and the ideal grow room will provide controlled wind stress.
Different Kinds of Ventilation
All grow rooms have walls but there might be differences in these walls. There has to be a door and this might be screened. There may be windows, existing exhaust fans, and air conditioning. And, what if your grow room is an aquarium or cabinet?
There are calculations that can be made to get the required amount of fans necessary in an enclosed space. That is for advanced setups, like those who do commercial marijuana crop production indoors.
The various kinds of ventilation options can aid you in your study of what to do and make it less costly to place air circulation and exhaust in your marijuana grow room.
Mechanical
Fans bring air in and out of a certain space. There is the exhaust which is just going out, also known as the passive system. There is the balanced that has both air supply and exhaust fans.
Natural
A room is designed in such a way that there is no need for fans for proper air circulation for normal use. Yet note, that the enclosed space of a grow room might require more ventilation than what is available as there are elements in the air that are not ideal for the marijuana plants. These elements include the water vapor that’ll add to the humidity level and the odor which might be unpleasant for you.
But, if the space has that light and breezy air, you might also have to add fans to use when it is not that way or secure the area to cover the openings when the wind is too strong and the weather conditions are not good for the plants like when it is too cold.
Mixed mode
This is also known as a hybrid. This is the kind of ventilation that has both mechanical and natural.
When You Just Need the Basics
If you have a grow room and are dead serious in creating the ideal growing conditions, you would require a sophisticated setup. Advanced growers and those who do commercial cultivation would have to budget for this expense.
Yet, as a home cultivar that wants to provide the best care possible, great growing conditions can be achieved with just the basic setup.
What you will need are exhaust fans and oscillating fans.
An Exhaust Fan is Also Known as an Extractor Fan
It works to blow out the air. When the air goes out, it takes along odors and water vapor, among other things. The exhaust fan serves to make the air circulate which does affect the room temperature such as getting rid of the heat. An enclosed area can be a hot box or super cold. There is another kind of fan that also works in sync with an exhaust fan. This kind is known as ducting fans. These can be placed in the ducting that’ll serve to channel out the air from the enclosed area.
An Oscillating Fan is that Common Electric Fan
There are different types such as a stand fan, desktop fan, and a ceiling fan. These come in various sizes and the intensity of the wind it can create also varies. There are oscillating fans that are stationary in function, meaning that it will just blow air one way, while there is one which has the fan part turning to the left and right to blow air in the direction it is facing.
Systems: Passive Air Intake and Active Air Intake
In a passive manner, all that is required is an exhaust fan. There is no air intake fan that will bring in the outside air. The way that the outside air will enter would either be through a duct or an intake hole, such as a small window, or small holes created in the wall. To make this passive system work, the air intake opening should be larger than the duct or exhaust hole. It is possible to create a number of intake holes for there to be enough suction like placing air intake openings on the different sides of the grow room.
The active intake is another option that is typically used for large sized enclosed areas. To apply this system, all that is needed is to place an air intake fan. That makes one fan blow in the air while the other one blows it out. The size of d air intake fan does not have to be much larger than the exhaust fan when creating this system.
Air Change
When ambient air is brought into an enclosed space intentionally, be it by natural or mechanical means, it will change the indoor air quality. This displacing and diluting of what is known as the indoor pollutants is done for more reasons than air circulation. It can provide dehumidification and thermal comfort.
When You Have Air Conditioners
If there is an air conditioning system such as that of centralized air conditioners or those stand-alone ones, there might be a need for an exhaust fan to aid in the air circulation so that the indoor air pollutants will go out.
It is possible to place a small split-type of aircon to use for air intake and that would also address the temperature control.
An aircon is the most common and easiest way to control grow rooms atmospheric conditions. It can get rid of the excess heat and even maintain the desired temperatures for optimal growth. It can also address the humidity control.
Design before You Create Ventilation
Fans and air conditioners cost money. You have to plan what to do before you start buying any appliance. The first thing to consider is where to place the appliances or how to work it out with the existing air openings. Then, you might have to take into consideration the electrical supply needed to run the fans such as sockets. Plan it well so you won’t waste your time and money.
You can do research online to find out what kind of oscillating and exhaust fans are available. You can also make an assessment of the room and use what you have. You can also ask an architect or other professionals to aid you in planning the air circulation and exhaust system. Make your dream marijuana grow room come true by investing your time and money wisely by planning.
