Yeast starter blew over questions

[crbice]

My yeast starter blew over and there is sediment in the airlock is that yeast and should I pitch it?

It should just be yeast in the airlock. I would pitch the stuff that didn't blow out.

1) Best practice is to not use an airlock on a starter. You are growing yeast not brewing beer and they need oxygen to do that-hence aerating, shaking, stir plate, etc.
2) Do not pitch what is in the airlock, just what is still in your flask/ bottle as what is in the airlock is not protected from contamination

So next time leave the flask open? I just built a stir plate to set it on would you recommend leaving it open for the whole 24hr process?

Don't leave it open, but cover with a sanitized piece of foil. Bugs, bacteria, and wild yeast can't climb, they just float around and can fall in. The foil allows your stir plate to draw O2 in and let CO2 out while keeping the wild things out
