Seed information Database ?

[Catwheazle]

Hi,
when sowing, I have some databases with information. Unfortunately, these are only limited to the temperature.
Is there somewhere information whether light or dark germ (e.g. cyclamen) and type of soil (e.g. gentiana): basic or acidic?

Greetings
Bernd
