Best 4 Inch Grow Fans For 2019

Inline grow fans play a crucial part in ensuring you get the most out of your cannabis plants. If your looking for a 4 inch inline grow fan take a look at the 4 most popular fans on Amazon with free shipping. I did the research so you can compare inline fans easy in 1 location. I personally use the Acinfinity cloudline fans and love them. That being said I was a long time user of can-fan and I still own a few of those as well.  All the products I am listing will link to Amazon with free shipping in Canada if you click the image. Fans are in order by price.

Best 4 inch grow fans

Can-Fan S 400 
CFM: 123 CFM
Speed Controller: No
Watts: 75
Loudness: 9/10
Weight: 7 lbs
Warranty: 5 Years
Price: $134.99

Can-Fan has been around for a long time. I first used their fans about 14 years ago and still have some fans running that are over 5 years old. They are not as efficient as some of the newer fans but they are super reliable. Compared to the cloudline from AC infinity this fan can be a bit loud other than that I have no complaints with Can-Fan.


Cloudline best 8 inch grow fans for 2019

CFM: 205 CFM
Speed Controller: Yes
Watts: 29
Loudness: 5/10
Weight: 5.20 lbs
Warranty: 2 Years

Ac Infinity is new on the market in 2018 I believe and making a fast name for them self with there stylish, quiet efficient inline fans. I purchased one to run some tests and could not be happier with things. the digital controller is a nice added bonus that will allow you to control and set warning alarms. the fan and the power this fan has for the noise is amazing.


Obionics Fan Iobio Pro 
CFM: 190 CFM
Speed Controller: Yes
Watts: 20
Loudness: 7/10

Obionics fans are quickly becoming popular on Amazon with great reviews, amazing efficiency and price to match. I have not personally used these fans yet but I do plan on ordering one in to test it out in the future and see how it compares to the cloudline from Ac Infinity. With a digital controller, this could be a good competitor with the cloudlines.


Vivosun grow fans

CFM: 190 CFM
Speed Controller: Yes
Watts: 59
Loudness: 7/10
Weight:  4.49 lbs
Warranty: 1 Year

Vivosun if you do not know is one of the budget brands on Amazon. I know a lot of people using their products who have no complaints and never had any problems but I also know a few people who had issues but they were cleared up through the companies support. Although their products are cheap they get the job done. I myself have never tried their fans yet but I do use their light hangers.
