When choosing the size and filter to go with, you’ll have to calculate how much cubic feet is in your grow room. You can do this by multiplying the length by the width and the height. https://www.yrdcarbon.com/
If you’re a gardener, then you can usually find these specs on your order, but if you can’t find it, you can always measure it with the tape measure.In an ideal situation, you want to exchange all your air every minute. To do that, your fan CFM has to match the cubic feet of your grow room.
If you’re using a carbon filter, you’ll want your fan CFM to be 20% more than the square feet of your room. In smaller tents, you’ll most likely only need a single 4-inch fan to move enough air.When using a single fan, we recommend using it as an exhaust fan instead of an intake fan so that you can use a carbon filter.Since carbon filters are used as part of an exhaust system, this will cause negative pressure inside your tent which plants don’t typically like.So to counter this, you can open one of the screen meshes. Exchanging the air of your room every minute is only if you’re not picky. There are a lot of growers who get away with just oscillating fans.
If you are a casual grower, exchanging your air every two or five minutes is usually good enough and from our experience hasn’t affected a yield all that much.It’s more important to stay at the right temperature, and humidity range, then change your air every minute. Your ideal temperature is between 70 to 85 degrees Fahrenheit or 20 to 30 degree Celsius when the lights are on and slightly cooler.When the lights are off, it’s recommended not to have a temperature drop greater than 15 degrees. The ideal humidity for cutting and seedling stage is 70 to 80%.Relative humidity for vegetable stages is 40 to 70%, and for flowering, it’s 40 to 50%.
In general, it’s okay to have a filter to be oversized for a fan or grow room because it’s not particularly important to exchange the air at a fast rate.However, it is generally not okay for a fan to be oversized for the filter because we won’t be able to scrub odors fast enough for most people’s standards.If you do have a huge fan for small gross space, you can always install two carbon filters around your exhaust fan. However, keep in mind it’s not conventional but it works.https://www.activated-carbon-pellets.com/
