Tips and Tricks to Setup Indoor Grow Room and Grow Tent Ventilation

Uncontrolled temperature, humidity, and light play a crucial role in plant growth. Further, even minor pollution affects the outdoor plants. That is why indoor grow rooms are an ideal option for many growers. Therefore, you can use some tips and tricks to set up Grow room environment. Like good quality fertilizer is vital for plants, proper grow tent ventilation and filtration can aid your plant's growth. Proper grow room ventilation is crucial for the healthy development of plants. Equally, suitable filtration is essential to clean the environment and remove all odors from the indoor environment.

You can try some ideas for indoor Grow room and Grow Tent ventilation.

  • Try to filter out the air in your grow tent or space approximately after five minutes when the lights are on.
  • You should replace the air more rapidly when achieving optimal humidity and heat levels is difficult.
  • Maintain temperature, reduce odors, strengthen the plant, and keep other factors stable by circulating air within your tent.
  • When planning indoor growing, you need a sound ventilation system and proper control of inner room environmental conditions.

Therefore, let's track down some valuable tips and tricks for improving ventilation and circulation within your tent or room.

Know What You Don’t About Active and Passive Airflow

Are you planning to set up an in-grow tent system? There are two ways to do it. You can go either with between an Active and Passive airflow system. The passive system works perfectly for the majority of grow tent planters.

The passive system works so that an inline exhaust fan sucks the air out of your tent, forming a vacuum. As a result, it pulls in fresh air from the intake ports. You will have to adopt a passive system if you deal with undesirable negative pressure inside the tent. Undesirable pressure means your tent does not have as much air pressure as the environment. You may have to deal with pest and odor issues if you do not seal the passive system.

In contrast with the passive system, you need an active intake system when you grow in a large Grow tent. Also, when you are planning to create the best environment for your plants. An extra inline fan is attached at the bottom of your tent to pull fresh air into an active system. It is very productive when you struggle with high temperatures or the intake port is smaller than the exhaust ports.

Ventilation System Sizing

For proper ventilation system in your grow rooms and grow tents, you need suitable ventilation system.

You can use the formula below to calculate the CFM (cubic feet per minute):

(Grow Space Width X Height X Length) / 5 = Recommended CFM.

CFM performance of the fan varies with the path and length of ducting. It also depends upon the type of filter you used for it. If you are using a carbon filter, it reduces fan performance. For this, you need to add an additional 20% to cover up the loss.

For a carbon filter, you can calculate the CFM as:

[(Grow Space Width X Height X Length) / 5] X 1.2 = Recommended CFM.

Determine the value of CFM and decide the best ventilation setup for your tent. You can also use air-conditioning and CO2 in the in-grow area to enhance growth. Use a carbon filter and fan combo to scrub the air. It will be more effective if you are using a sealed room.

Some Common Tent and Grow Room Ventilation Setup

There are four ways to design your tent ventilation system – fan and filter inside, fan outside and filter inside, the fan inside filter outside, and the last one is both fan and filter outdoors. Remember, CFM performance is affected by the length and path of ducting. It is best to use a short and straight way of the duct.

Setting Up Ventilation System- Five Easy Steps

You can set up an inline fan to the exhaust port and carbon filter in many ways. Further, the type of grow lighting system you install and how you position the lights will determine how it functions in your grow room.

Arrangement of the system makes sense when your tent and ventilation component is in front of you. Setting up a system is a bit difficult for LED, CMH, and fluorescent handlers. You have to join the reflector with other components.

Process Step-by-Step

Step one – attach extra ceiling bars to your tent with an inline fan. As the fan will hang only a few inches from the ceiling, an adjustable rope clip handle is the best option. Now connect your inline fan to the duct, which can run in and out of the exhaust hole. Then hang your scrubber that comes along with ropes. This step is followed by attaching the scrubber with an inline fan so that it pulls air through the scrubber.

Lastly, confirm that the components are attached properly. Outside air is pulled through the bottom inline port up into the filter, passing through the inline fan and exiting through the exhaust.

Set Up for Reflector User

The setup is a little complex for reflector users as there would be a need for HID. Using airflow directly through the reflector result in cooling the bulb. Check out the complete grow tent setup guide to know more about the setup.

How to Deal with Humidity and Heat in your Tent or Grow room?

After setting up a system, if you are experiencing temperature above the desired level, that is 78-90-degree Fahrenheit for seedlings and 72-76-degree Fahrenheit for mature plants, it's important to maintain by using another method. You might know humidity control varies in a closed and open system. Above all, injecting CO2 will not be effective if the temperature is above 85-degree Fahrenheit or below 55.

In an open system, an air-cool reflector can use to ventilate light. Further, hot air reduces temperature. Additionally, air conditioning can also come in handy for high temperatures. From our air conditioning range, a mini-split is very popular.

Another factor that plays the vital role in controlling Grow room environment is humidity. You can add dehumidifiers to improve the overall environment of the in-grow system. We have a wide range of dehumidifiers, varying from small units to commercial-grade units. Learn from our guide on how to deal with grow tent heat and grow tent humidity.

Odorless Grow Room

A carbon filter eliminates the pungent smell from their grow room. However, you need to check the working life of the filter. You can also shake the carbon filter to see the unused carbon particles in some cases.

Another way to reduce odor is by using an Ozone generator and neutralization by using chemicals such as Ona's gel-based product.

If your room environment is not fresh at the end of the day, the plants you grow will have a pungent smell. You can use a carbon filter 24/7, but this messes the environment, removing all the moisture. You can also look into our post on how to grow room odorless and make it more pleasant for both people and plants.

Grow Room CO2 and More Pointers on Ventilation

If you are complimenting your grow room with CO2 – the best setup is a closed-loop. Try to create an environment from which CO2 will not escape. The absence or lack of CO2 is not an ideal scenario. Find an alternative to reduce heat and odor without venting air out. Check out our guide on how to use CO2 in a grow room. In our guide, you will also learn how to utilize it carefully and efficiently.

Ducting Tips and Tricks

You might know that ducting can diffuse light – it causes proof-grown room if not correctly set up. Create "u shape bend" in your duct to avoid light leaks. The screen works well if you use it where your duct makes it exit from the structure. The screen prevents pests and other flying creatures from entering your in-grow system.
