I bought my first nucs this year. A month later, no drawn foundation on plastic and a terrible mess. I ordered supercell, sprayed it down with 1:1 and rubbed it with warm wax. two weeks later all frames occupied and working. I slowly worked the wax out from the center, removing two frames every ten days or so. However, when I added the second deep, I used two of the original wax frames as bait and to give them a place to raise drones and add queen cells as needed.
Hope this helps in some way.
P.S. - still don't know if I can put the supercell in an extractor or not. Dadant doesn't even know what it is.
Later,
John.
