Ok so just a question because I think I got it right but making sure. When I assembled my Hive Kit the 2 Full-Size deeps had Black plasticell for one and Yellow for the other. Then my 2 Medium Supers had yellow plasticell. So the Black Plasticell is in the Bottom Deep and yellow in the top deep. So is this because the black is where they like to keep the brood and the yellow makes the bees think Honey?
