Re: Shallow Super
You will be fine. You didnt say if you had bees, so considering you were painting your boxes, by the time you get bees, I doubt you will even fill more than one shallow this year. I use deep hive bodies with shallow supers, much lighter as you mentioned. Get your hive established, and once its booming you may decide you want to use mediums instead. A little unsolicited advice; two hives are better than one, if one is failing, you can almost always save it using brood from your good hive. With one hive, if it fails then it fails.
It takes a family to raise a family, it takes a village to really screw that up... Djei5
