Hi G3 and Barry
Because I haven't had any hands on experience with any other hives other than my own for the last three years, I've had to learn some stuff the hard way. From what I understand about my top deep, is that the frames were not spaced correctly and a bit crooked allowing the bees to form comb in all different directions. I'm in the process of slowly correcting this problem this season.
Barry, before I trasferred my small patio hive into the standard lang, I read that nine frames in a 10 frame lang.. leaves room for the grooming bees to drop varroa mites down thru the frames, thru the screen bottom board, and onto the sticky board, suggesting another way to manage mites. Boy! was that a bunch of malarkey! Hense my first and formost problem to solve this season, my fourth.
I'm also in the process of swapping out all the plastic, and my implants.. to all wood frames and wired wax foundation. It might even take a couple of years. But I'm not in a hurry, and my hive is healthy and bustling. And so I continue to learn ~
