Okay that was going to be another of my questions, how often to spritz or if you need to change out the vermiculite for new moist vermiculite if the other dries out or how you maintain that. I wonder how much water I would put into a wine chiller to keep the air humid without making it too much so that it hurts the eggs. I think I am going to end up running this thing for months before the eggs come to make sure I have all the temps and everything right lol.
