---------------Original Message--------------- REGARDING Plastic frame usage I have used a limited number of Pierco plastic frames for a number of years in the honey supers, but never in the brood nest. I think your missing a great management tool, by not using them in the brood nest. They worked well for me after the first season, when the bees had to be coaxed into using them. They are very easy to uncap, either with knives, planes or automatic uncappers. The main drawback I see is that they are quite heavy compared with wood and beeswax comb frames. Actually, empty they are lighter than wood and wax, but when they are full of honey they are heavier, as they hold 15% more honey. Just a few notes I thought I might add. I would be willing to respond to any questions you might have. Ted Fischer TPLR HONEY FARMS Tim Townsend RR 1 Stony Plain Alberta [log in to unmask]
