How about trying to use words like nursery in your search, that way you may get sites and information from people who actually grow the plants professionally. The thing you wil find is that there may well be conflicting advice out there, it can often be a matter of trial and error to see what suits your plant in your conditions. I have often found that I get the general gist from a couple of nursery sites online, but then find that I need to do something a little different.
Have you tried looking through the "ask the senior members" part of the
forum, as there is a lot of information on this
forum where people have discussed what they do and how it works for them.
