I remember growing a starter over 20 years ago and abandoning the poor thing. Now I am older and wiser and want to make another go of it all. I have been reading these related threads til the wee hours and have yet to find an answer to my remaining question before I get started.
When you are feeding your young starter and it is setting out at room temperature do you cover it in any way? Loosely? With paper towel? Plastic wrap? Or tightly as with a jar lid or a plastic food storage container?

I didn't want to hijack the other question where BROTKUNST suggested a turkey roaster cover so I thought I would start another thread.
