There are various sizes of grow spaces, each requiring a different amount of airflow to ventilate them. Exchanging stale air inside with fresh air from the outside of your grow space is vital for optimal plant growth.
How much airflow does a grow room need?
Air in your grow area should be exchanged at least every 5 minutes. If you are using a grow tent that is 5′ x 5′ x 6′ this is 150 sq/ft of air. For optimal airflow, you need a filter and fan that can move between 30 and 60 cubic feet per minute (CFM). It is also important to balance the flow in and out of air.
How do you vent a grow room without windows?
Ventilation strategies for spaces without a window
Leave the door open. Use ceiling fans or portable fans. Mechanical ventilation on the outside. Passive outside venting. Use of an air conditioning system. An effective extractor fan. Introduction of plants that purify the air.
How often should exhaust fan run in grow room?
Ideally, your extractor fan system should replace the air in your grow room every minute, or at least every three to five minutes. This means that you need to choose the right size fan for the job.

If you’re relying on passive intake, remember to ensure that the intake vents in your tent are open. Also, keep a window open near your grow room to help replace the hot air being vented out of your tent. If you’re using active intake, instal your intake fan at your tent’s intake vent.
Where should exhaust fan be placed in a room?
Another consideration is that the fan should be located away from the intake air source, such as a door or window (if the window will be open). If the window and door will be closed, make sure there is a 5/8” or greater gap under the door to allow fresh air into the room.
Is it good to leave my fan on in grow tent?
At the vegetative stage, the plant will need enough airflow to strengthen its branches and also ventilate the Grow room. This stage its critical for farmers. You need to keep the fans running during the light hours. This will help prevent humidity and heat affect your yield.
What size fan for 10×10 grow room?
For a 10′ x 10′ space, assuming you have 8 foot ceilings, you’re cubic footage adds up to 800 cf. This means you’ll need an exhaust fan with a cfm rating of around 160 in order to remove the air every 5 minutes.
Does a carbon filter have to vent outside?
It isn’t necessary to have the air being pulled through the carbon filter exhausted outside your growing area; depending on your setup it may even work better to have the filtered air returned immediately to the growing area.
Can I exhaust my grow tent into same room?
Duct out to A Different Room
In case you don’t have a window, the next possible option is to vent out the air through a different room. It can be the room next to it or even the adjacent bathroom. In either case, you’ve to build up a ducting from the tent exhaust to the other door/room.

Does a carbon filter need to be on all the time?
When carbon adsorbs contaminants like chlorine, the molecules, ions or atoms from the chlorine collect like a film on the carbon. That film is called an adsorbate and it is the reason why you need to change your activated carbon filters regularly. There is only so much space for the adsorbate to collect on the carbon.
How long should I leave a fan on my seedlings?
Keep the fan running 24 hours a day. In addtion to helping prevent disease, the constant air movement will help develop stronger, sturdier seedlings. Plant your seeds in fresh soil that’s formulated for seedstarting. Never re-use potting soil because it can carry disease.
