Grow box fan placement/help

[Boji Stoner]

Hey I need some help, I just got into the growing business and I'm building a grow box. I have everything I need and I know how to wire everything, I was just wondering how do I put my fans in my grow box? do I just drill them in or do I cut a hole for them to go into?
Thanks.

Well if they are intended to pull air in or out of the box, you will certainly need to drill holes. If they are intended only for circulation of air inside the box, holes are not needed. Just mount them however you like (not flush with the wall obviously). Hope this helps.

They are intended to pull air in and out of the box. How would I go by making the holes just get a circular saw bit and cut the hole?

Yes if you can get ahold of the right sized hole saw drill bit. If not you may be able to drill a few holes in a cluster with a larger regular bit and just mount the fan flush to the wall over the holes.

Just did this to exhaust my small grow box I built because I used a pc fan that was 4.5 inches around and the hole saw bit was like $20+ dollars. I just printed out an outline for a 4.5" circle online and traced in on my box and drilled out a bunch of small holes in the middle of the circle and the just shave the edges down with a small hand wood saw and a little bit of sanding with a power sander which isn't needed I just had it handy. I now upgraded to a ventech 4 inch inline fan/carbon filter combo but the pc fan worked great. Kept my box between 70 - 80 F with passive intakes.

Awesome handiness. I did the same thing when I had a cabinet. Just couldn't justify buying the hole saw for one hole.

Yeh I know what you mean. I was like home depot must be crazy if they think I am about to pay this to drill 1 hole!

And you can bet they wouldn't let you return it afterward. (I'd be lying if I said I didn't consider trying that...) =]
