Hey guys, noob here. Excited cause I will be starting my first grow soon! (Turning a minifridge into a growbox)
Anyway, being cheap I somewhat came up with my own idea for a simple small carbon filter, mainly inspired by This Thread.
So here's my plan:
I will start with this mesh pencil cup, it's 4.2 inches around and about 5" tall.

Next i will take a standard carbon pre filter, like this one:

Cut it to size, and wrap it around the cup, securing it with zip ties and duct tape.
Lastly I will stick my 4 inch inline fan into it (100cfm). My hope is that because it is somewhat conical the fan should fit into it nicely.
Excluding the cost of a fan, this could be the cheapest filter I've ever seen, with a total cost of under 10$.
How does it look to you guys? I guess my main questions are:
1. How many times should i wrap the carbon filter strip around it?
2. Will a 100cfm fan be able to push enough air through it to accommodate a passive intake? (My fridge is a decent size, I'd guess to be around 3-4 sq feet)
