They will not bloom without appropriate light whether they are mature or not-- that's the first thing. In "the wild" so called, when they get maximum light levels, they tend to grow faster and thus bloom faster. So for faster results, higher light. They also need calcium and other minerals that are not found in potting mix or in many brands of fertilizer. The strap leafed paphs are generally lithophytes, or semi-terrestrial, and grow on cliff faces in overcast sun.
Oh, it is easy to get frustrated with "strap leafed" paphs and so on due to slow growth. I don't think that is any reason not to try to grow them. I don't think that orchids are "instant gratification" type plants.
