What unit of photometry is used to assess plant growth? Is there a catalog that lists plants and the required light exposure? I'm looking at more detailed indicators than "a lot of light" or "not too much light".

    This question appears to be off-topic because it is not a topic covered by this site (see the help center). I would ask it at biology.stackexchange.com.
