:leaf:Hi! I am new to this forum. Looking around last couple days. I want to make a grow room. What is the best fan/blower to use for a 5 by 5 by 5 size? This is to blow cold air in from the outside if that makes a difference in the type of blower. Thanks, Budhambre:leaf:

The one tip I can offer you as far as exhaust/intake is that you want a bit of negative pressure (more exhaust than intake) within your room.

Well some Centrifugal fans are better than others. It's obvious that you will be running ducting.

Depends on your exhaust flow. If it is highly negative pressure then you might away with no fan but depending on that means it has to be the right atmospheric conditions.

So what is your exhaust volume?

Also what kind of set up is it?

I am trying because I have had a focus on Convection in the 10 years since I first grew a medical crop.

In Short the best fan is the one that does the job well and costs the least.
