The agricultural sector is one of the areas in the world that are fully relied upon for survival and existence. The sector has been going through a series of upgrades and inventions for many years since the agrarian revolution. Today, things have gotten even better with the introduction of new farming technologies to increase food production. The use of grow rooms is one of the ways sustainable food production which is one of the global goals for this century.
A grow room is simply a room of any size, could be a simple home gardening room or a commercial growing place, where plants are grown under conditions that are controlled. There are many reasons people use grown rooms. Some use them for illegal farming of prohibited plants to avoid criminal repercussions, while others do it because it is the only way. It is important to understand the difference between a greenhouse and a grow room. While the former is partially sealed, the latter is completely sealed. Some may confuse a grow tent with a grow room but they are different. Grow rooms have many benefits; they make the plant growing a possibility even where there is no garden.
As much as grow rooms are an easy way of ensuring productivity, they require a lot of knowledge for proper maintenance; otherwise, there will be no benefits. Since they are completely sealed, it may be impossible for plants to receive ventilation and light. This is why understanding the necessary conditions expected to ensure success with grow rooms is important. Ventilation is very important to plants, they need air and light for proper growth. Plants that lack proper ventilation turn yellow due to lack of chlorophyll.
To better understand how it is good to know the why? The first reason why you need your room ventilated is to remove excess heat since grow lights emit a lot of heat. A little change in temperature can bring a lot of differences. Humidity is another factor that affects indoor gardening. Since plants emit vapor throughout the day, ventilation helps control the humidity which could lead to pests and diseases. But in the event your grow room is not getting enough vapor, you can use a grow room humidifier to provide your plants with enough vapor for them to grow. Ventilation helps prevent pests and diseases to which indoor plants are vulnerable. Dump top soli encourages pests to lay eggs on. For the nutrient cycle, plants absorb CO2 every day making the level of CO2 to decrease constantly; ventilation ensures there is proper supply. Ventilation also helps prevent wind stress.
Now that you understand why, let’s now look at how to ventilate a grow room.
It is important to note that your grow room needs two types of fans; air extractor fans and oscillating fans. Oscillating fans blow air constantly above, under and around the plant. It circulates air in the room to keep the room cool. These fans are cheaper, easily available and easy to install and use.
This system provides a cycle of air by replacing the old air with new fresh air. This should take place every minute, or at least after every three minutes otherwise your plants will suffocate. Choosing the right fan size is, therefore, a priority.
It is one thing to have ventilation in your room and another thing controlling the amount of air needed. You may need a little bit of math to calculate fan speed though it’s simple since fans are rated by cubic feet per minute (CFM). You can figure out CFM needed by the dimensions of your grow room and the exhaust efficiency. You simply calculate the volume of your rooms then multiply by efficiency drop. The formula is room volume x efficiency drop= CFM.
Passive airflow and negative pressure determine passive intake. With this ventilation, you may have a fan blowing air out but not in. instead, you may use a hole to bring air in. Active intake systems, on the other hand, have air drawn actively into your room with a fan.
Humidity comes due to transpiration and must be controlled; otherwise, it may cause problems for the plant. Lowering humidity can be done by venting the humid air out using exhaust system. You can also use a dehumidifier. You may need to raise humidity sometimes by simply turning off your exhaust temporarily.
Plants need CO2 for transpiration. All you need to do is inject it into your grow room. The injection requires a completely sealed grow room for efficiency and safety. You need efficiency because CO2 works better for plants at high concentration. Safety comes in due to the fact that plants need more CO2 than humans do, you don’t want CO2 leaking into your room.
As discussed in the previous section grow rooms require two kinds of fans oscillating fans and air extractor fan system. The oscillating fan simply blows air all around the room while air extractor performs a more advanced role of cycling air; old air replaced with new air.

Finding the right size of fun for your grow room requires a little bit of math. This may sound complicated to some yet in the real sense, it is very easy. All you need is to calculate the volume of your room, length x width x height, example 10x10x10. After this, calculate the CFM required. The fun should give you an exchange in an indoor room once every 3mins. Therefore, 1000 cubic ft /3 minutes will be about 333.3CFM. You can then use this information to calculate the ventilation required including other factors.
The fan size required for a grow tent can be calculated the same as the one for grow rooms. you calculate the volume of the tent and the CFM required. Multiplying the CFM with efficiency drop should give you the amount of ventilation needed and therefore the fan size.
I hope you find this article on ventilation and best grow room fans quite helpful. With this knowledge combined with practice, you can easily become an expert in grow rooms and grow tents. Success in this activity depends on choosing the right ventilation system and understanding some basic required for operations. It is not that hard to manage a grow room and anyone can do it.
