Yes, the easiest thing to do is find the beams. You can purchase a "stud finder" at any hardware store. Once you find the beam(s), use a drill to drill a small hole into the beam. Thread the hooks into the holes, make sure you then test to see that the hooks are secure. An inexpensive drill can be purchased at the hardware store as well as the drill bit you will need to drill the holes.
You can always tell the sales clerk that you are hanging a large plant and ask for help in locating the items to do so.

I never thought of it but, I would imagine that quite a few of us have "hanging plants" in our bedrooms.
