In hotter regions keeping your corms dry when dormant is not that all important, given that you have given them good drainage to begin with. I know the books say they demand to be totally dry when dormant, but I have found this not to hold true. But, in cooler climates, regardless of your good drainage I would play it safe and keep the corms dry when dormant. Plants if over watered can rot. Again, by growing from seed, and finding more than just one source, you are allowing for genetic diversity in what you grow.
Nature is very adaptive.
