Polystyrene Nucleus Hive Made from a very high density, 100g/litre material that is upto 3 times stronger than the material used for packaging. Lightweight, durable insulation properties make it especially suitable for nucs and small colonies as fewer bees are required to maintain the heat required for effective brood rearing. | | National Bee Hive Totally compatible with both our wooden National hives and Poly National hive components. This gives you the ability to use your existing wooden supers on the top, or use poly supers on top of your existing wooden brood box. |
