How Important is it to Calculate the Size of the Grow Room Fan?

The addition of the fan in the grow room plays a very important role in order to keep the air inside it clean.

However, selection of the grow room fan is a concern for most people, especially the first time hydroponic gardeners. If you are one of the new gardeners and have absolutely no idea on the selection procedure of the inline fan, then here is some important information that you could need.

Growers move towards this in two dissimilar ways.

Passive air intakes are simply holes that allow fresh air in. The simple act of extracting air will cause the air pressure in your garden to drop so this fresh air will be pulled in through any gaps present. Using the principle of - the larger the gaps, the more air there are certain conclusions that have been made. Like water, air will always find the easiest path of least resistance. Passive intakes can take the form of vents or even, at its most crude, an open window or door. We don't recommend this as you want to keep as much control over what comes into your indoor garden as possible-particularly with regard to bugs which can cause a problem.

Active air intakes are typically smaller inline extraction fans that blow fresh air into the garden, rather than relying on air pressure. This is preferred by many growers because it puts less strain on the extraction fan and actually helps it to work more efficiently. The intake fan should be connected to an inline air filter to guard against bugs getting a free ride into your garden.

The Calculation Method:

If we run this equation through our example indoor garden it gives us;

Required Fan size (CFM) = (Volume of Active Growing Space) x 1.33

(8 x 8 x 8.2) x 1.33 =698 CFM

Even though it may not seem to be like a standard equation by all, you can still use this equation to get the desired size in approximate.
