Larger grow tents can benefit from using passive air intake as well but will require higher CFM exhaust fans. Air intake is only a part of the indoor growing equation. Many factors like grow tent size, grow lights, and inline fans contribute to creating the optimal growing environment.
Where should I vent my grow tent?
In this case, you may set the fan and/or filter outside of your grow tent. We recommend setting your extraction fan at the highest point possible. Since heat rises to the top, exhausting that hot air at that point will make the ventilation process efficient.

Should I leave my fan on when lights are off?
When lights are no more on plants, no more heat is generated. And the photosynthesis process takes a break. However, plants keep breathing and leaving vapors around the leaves. So, oscillating fans still need to be on duty.
How much can a 4X4 grow tent yield?
The final yield in a 4×4 grow space is 1.5-2 lbs. Also, because the plants are large in size, ScrOG or single plant growing is preferred for maximum yield.
How long should you run exhaust fan in grow tent?
You need to keep the fans running during the light hours. This will help prevent humidity and heat affect your yield. During the dark hours, keep the fan off after 1 hour. Let the plant flower without any disturbance.
How many plants grow in a 4X4 tent?
Most growers prefer something in between these two extremes with around nine plants in a 4X4 grow space. This will give you about one square foot per each plant. Auto-flower plants will always be the same size as they do not have a veg period.
How do you ventilate a grow room?
Different Ways To Ventilate Your Grow Room

Does a sealed grow room need fresh air?
The concept of a sealed room is quite basic; a sealed room is a growing environment where there are no holes or air exchanges to the outdoors or any other room. It doesn’t need to be airtight, however, the closer to airtight the better.
How often should I vent my grow tent?

How often should air be exchanged in grow room?
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.
What is a passive intake grow room?
A passive intake is an opening in the wall of your growroom or tent that is designed specifically to let fresh air pass into the garden. These systems work through your inline fan exhaust system as it pulls fresh air from outside, while expelling stale air.
