Using a stir plate

So I am not sure where to put this, but I bought a stir plate and I don't know how to use it to make the starter. I know how to use the physical stir plate but I don't think I want to say, air lock the container with the thing string because air can't get in... or can it but it passes through a water filter? I am use to making starters the old fashioned way and wanted to try something new and fun. I suppose if I have to I can also get the bottle thing which filters the air going into the growler, but I am curious about how you all do it.

Thanks!

Wort, approx. 1.040. Add yeast. Put foil loosely over flask or whatever container you're using. Put on stir plate. Watch your sea monkey propagate.

Right. You don't want to seal the container while using the stir plate. I use a large flask, and simply cover the opening with an overlap of aluminum foil. The foil keeps bugs from drifting into the container, but also allows gas exchange.

AHH! That was my mistake before. I used Serran wrap when I made a starter without a cap. That thing exploded all over the place... aluminum foil... excellent. I will try it this weekend! Thanks!

This is how I make my starters http://www.mrmalty.com/pitching.php
I make starter about 24 hours before pitching.

This is an excellent resource for starter volumes/pitching rates. I use a 2L flask on a stirstarter. I use a foam stopper

but a loose piece of aluminum foil works well to.
