In the overall, what size fan for 4x4 grow tent? So for a 4x4 grow tent with an area of ~106 cubic feet, a grow tent fan (inline fan) rated for ~215cfm would get the job done.
Remember, you must get an inline fan if you are using a filter in a small grow tent. Going back to our example, a 16 cubic feet grow tent that has a carbon filter should now have a fan of at least 32 CFM.

The rapid air movement caused by a fan can dry out your mouth and nasal passages, your eyes and can even cause dry skin conditions, according to Mark Reddick from Sleep Advisor. Reddick says: “As a fan moves air around the room, it causes flurries of dust and pollen to make their way into your sinuses.
Less frequent starts and stops of the fan can reduce the stress from startup, and potentially help extend it's lifespan. Leaving the fan on 24/7 ensures cleaner air, as the air is pulled through the filtration or UV light system.
It's okay! Fans are made to run for extended periods of time. A quality fan should have no problems spinning that long. Some exhaust fans can even run 24/7.
To calculate multiply length x width x height of growing area e.g. A room that is 8' x 8' x 8' will have a volume of 512 cubic feet. Your extraction fan should be able to adequately exchange the air in an indoor garden once every three minutes. Therefore, 512 cubic feet / 3 minutes = 171 CFM.
Well, the style and number of plants to grow in a 4×4 size really depend on the way you're training your plants, the strain and so on. If you're growing SOG: 4–16 plants per m2. If you're growing Pruning: 1 plants per m2. If you're growing with low-stress training: 4 plants per m2.
Now you need to calculate the volume of your room so that you can work out which size extractor fan you need. You simply need to multiply the width by the length by the height. This will show you the volume.
2x2 you shouldn't need anything more than a 4”. Ive got a powerful 4” fan for my exhaust in a 4x4x8 and it's plenty strong. I would also recommend getting a dimmer/control switch for it as well for variable speeds.
Fans that continue to spin quickly and make abnormally loud noises might indicate a problem. Common causes for fans not working, abnormal or loud fan noise, overheating: Fans or air vents that are obstructed. Dust accumulation on vents or fans.
Your indoor or outdoor unit could be so loud for a few of the following common reasons: Most units use isolation padding to absorb the motion noise produced by the internal parts, especially the fan. These pads can wear over time and begin to crumble and break, increasing the noise level of your air conditioning unit.
A problem common to both types of fans is excessive noise. Accumulated dirt can cause noise because it can unbalance fan blades and wear out bearings. ... Check to see that the fan guards are firmly attached to the fan housing. If the blade guards still rattle, try wedging a piece of cardboard between their edges.
The smaller the pipe size drawing air from under the membrane the quieter the air flow noise. To reduce sub-membrane noise, downsize the pipe under the membrane to a 2" pipe which can move up to 50 cfm or a 1.5 inch pipe that can move up to 35 cfm of air.
