New to genesis rbas. Have been able to build a few coils that actually allow me to vape. Watched vids about hotspots, and when i've built my coils i've "fiddled" with them until all the coils glow, but what exactly am i trying to accomplish with the fiddling - get the coils in better contact with the mesh wick or get less contact? Just move to coil to a slightly different area of the wick?
