The cultural information should be used as a guide only, I have found a number of different sowing techniques for the same seed from different sources there does not seem to be a standard. With this in mind you should use this website as a guide only, you probably already have a tried and tested way of sowing different seeds. As a rule of thumb the larger the seed size the more cover it requires, and fine seed like Lobelia, Begonia etc requires no cover.
