It is possible to cure gel nail polish with plant grow lights, although their effectiveness may be inferior to that of UV or LED nail lamps designed specifically for the purpose.
UV and LED nail lights produce specific wavelengths that trigger the photoinitiators in gel nail polish, speeding up the curing and hardening process. Plant growth lights may not offer the proper amount or wavelength of light needed for the best drying of gel nail polish, even if their light output covers a wider spectrum.
If you use plant grow lights, the gel polish may not cure completely, it may cure unevenly, or it may take longer to cure. Using a UV or LED nail lamp is advised if you want the best results and a long-lasting gel manicure.
