I use 3 mediums for my brood area, if the hive is weak, I put on a honey super then when things are going better, I will put on the RRs. If the hive is strong coming out of winter, I put on the RR super on right after the bees have restored their own stores. A few years (not recent years) I was able to put the RRs on twice durning the flow but let the bees determine when you put it on. -Mike
