I keep my corns in the same rack as my BPs. Right now they are on the lower two shelves and have no heating, the room is set for low 80s.

But previously, I had the corns hot spot on the same thermostat as the BPs cool end. That gave them a range of 78 - 82.... worked out well. I will probably do that again (soon).

If you have a thermostat that controls your cool end, you can use it as the corn's hot end and just leave the other side as unheated. Just check your temps and see what you come up with in the end.
