Remember, too, that humidity varies over the diurnal cycle. In a natural environment, it will be higher at night when it is cooler. So if you let that natural process operate, so that the plants have a chance to dry out during the day, experiencing a cooler, damper night, I think that you greatly improve the chance of not running into fungal issues.
