Don't!
You don't need to agree with how I do it, but no two people will get the same results, so we each need to do it how it works for us. I don't lid my FF. I don't store it outside either. I keep it temperature controlled inside, I keep it on the dry side, I feed it anywhere from 24 hrs to 5 days old, and I reuse the same dirty jar for the next batch. That's what works for me.
