Provide as much light as you possibly can for your FLF and hope that it is enough. Don't waste your money on a light meter. The only ones that are reasonably accurate are very expensive. Just keep your plant as close to your sunniest window as possible. No need to know what the footcandles are.
The mister will provide little or no benefit to the FLF, which does just fine in very dry air as long as the roots are kept sufficiently moist.
Hearing aids are very expensive, but well worth it if you can afford them. I know from experience. Todays' technology is so much better allowing for improved hearing with very small, unobtrusive devices. Most folks are not even aware that I have them.
