Does the pierco seem as sturdy as wooden frames or a little better? I too like that they are out of the box and into the hive. I am just getting started and waunt to buy quality equipment to start with.
I use Pierco if I have to buy foundation. I have some miscellanous wooden frames acquired through nuc purchases, plus some that I have used to insert comb within when doing a colony transfer from a feral state to a regular hive enviroment.
The Pierco is very sturdy and will take some punishment; As much as is needed for a beehive.
The bees will build comb IF and WHEN they need to and that has been my "short" experience. They WILL draw out the Pierco readily when there is a honey flow, and for me they did a beautiful job last year in a nine frame/medium honey super
You should pay attention to the time of the year " season " to get an accurate assement of what YOUR bees are doing in YOUR locale.
I discussed the Pierco with long time beekeepers and some think it's OK and some prefer all wax. The Pierco is dipped in wax and smells and feels like wax. Plus, no work to assembly.
Of course there are many oponions on the subject but some are wrong.
as in all things.
