I installed a package on plastic foundation in wood frames on April 17th this year. I fed sugar syrup and they started drawing the foundation immediately. As of a couple weeks ago, they had one deep completely drawn and a shallow on top of that completely drawn and full of bees, brood, etc. At that point, I stopped feeding and added a 3rd super (another shallow). The third super contained nothing but plastic foundation on wood frames. We have a honey flow on here, and now the 3rd super is about half drawn out and is quickly getting filled up with nectar/honey. So, the plastic foundation in the wood frames seems to be working just fine for me. When you put plastic foundation on, you need to feed them to get them to draw it OR there must be a good honey flow on. I wish you the best!
