Re: Plastic Drone Foundation Sheets
You will have the problem of keeping the queen off of them. Plastic foundation is easier to get drawn out with no queen excluder, but if the queen lays in that drone comb you can have one hell of a lot of drones being raised. Your problem is probably thick honey, which is easier to extract with a tangential extractor. Yes, get it as warm as possible.
All of my opinions and suggestions are based on my five decades of actual beekeeping,
not so much on book learning, watching YouTube videos nor reading internet sites.
