Mold+Nep Seedlings=Problem?

I have some germinated nepenthes seedlings in small 3-inch pots that are growing wonderfully. The issue seems to be some grey-ish/white mold growing upon the media. It hasn't caused any problems yet, but I would really like to get rid of it before it does. It is growing on just some dry LFS that I powderized before I sowed the seeds. For a general idea on the size of the plants, they are just starting to get their second carnivorous leaves.

Now, heres the catch. I am an extremely poor college student, with access to a single, poorly stocked ACE Hardware and a Wal-Mart Supercenter in the immediate area. Is there something I can use thats pretty cheap, and that I can get at one of those stores? Thanks guys!

I am having the same problem with some Drosera seedlings. I look forward to an answer.
