I just made a yeast started and just realized i didnt have an airlock for it so i am using tin foil. Is this ok for a yeast started? I have never used tin foil for a yeast started but my LHB shop is closed for the weekend and i have no choice now.

I only use tin foil as a cover for my starters.

I just spritz with Star san and put on snugly.
It won't blow off, the gases fermentation creates build slowly and just leak out.
I often had trouble with the airlock getting stuck in the neck of my flask from any residual sticky wort, the foil stops that also.

I made one in a growler and just loosened the lid a little, about a half turn. Worked great!

+1 to the foil. I use it every time and just spray with sanitizer before securing it on there. Not sure if this is true, but I feel like it allows oxygen to get in that an airlock would not allow. Oxygen would be a good thing in the case of starters.

That's a good point. I will occasionally grab the flask by the neck so I hold the foil in place and give a good swirl whenever I happen to walk by. You want there to be air exchange to help the yeast go.

I've never used an airlock for a yeast starter, only sanitized foil.
