DO NOT USE COTTON!
It's not a genny at all if you put cotton in it! Gennies use mesh and mesh only. If you want to use cotton get a dripper, and don't build a genny as something it's not!

Mesh with a thin cotton center, done right, will wick like a leaking faucet. I can actually keep the fill plug in place and vape with the wick on the high side of the tank.
