If your getting dry hits, remove the build deck and if the wick is still wet you haven't got it tight enough through the mesh.
If the cotton is looking dry, cut the wick a bit shorter that goes into the wick slots so there is a small gap, and make sure if isn't really tight and stuffed into the wick slot, nice and fluffy. That's how wet my wick looks after pulling out the build deck. I would say I've used 3/4 of a strip of cotton bacon. I've updated the original post as I found half a piece isn't thick enough.
