Answer: This is an interesting question. I would think the butter compartment is okay to use. You could flip it open for just a second or two once a day to assure a little air exchange. (At my house I know that would be safer, less chance of spilling the seed container.) My concern is that it may dry out too much without any covering if stored in a modern, self defrosting refrigerator, but I would think the company would be giving you good directions for its product. I would really suggest you contact the company for more specific instructions where you are not sure. As far as the water goes, the reason for using distilled or rainwater is to avoid introducing chemicals into the closed environment, so definitely use the recommended kind from now on. Here is some more information about growing these from the carnivorous plant society you may find interesting. (Note that different types have different germination needs.)
Good luck with your project!
