Eight frame wooden bee hive equipment is lighter than 10 frame equipment by approximately 20 percent. When full of honey, a full 8 frame medium super will weigh 40 to 48 pounds while a full 10 frame medium will weigh 50 to 60 pounds. Some feel that overwintering is better in taller 8 frame bee hives than 10 frame boxes because the cluster can move up more readily through honey stores in a smaller 8 frame hives.
A Beginner kit is a hive plus a book, smoker, hive tool and some basic protective clothing, like a veil and gloves. Essentials kits have hive equipment for the brood nest. An Increase kit is hive equipment. It is what you may want if you have a hive, clothing and a smoker and want to add other hives. Supering kits are to add honey supers to an Essentials kit or an established hive. It's possible after a year or two of having honey comb created (or 'drawn out') that a strong hive will need 4 supers from then on.
