Tried the search function but couldn’t find an answer. I am doing my first starter right now. How do you know if it’s doing anything/ growing? I made a 1 liter starter in a 2 liter flask and it’s on a stir plate with a decent whirlpool in the center. The opening is plugged with a foam stopper. I plan to pitch it (WLP004) late tonight into an Irish Stout ≈1.044 OG. It should be 24+ hours since it was started. The pure pitch packet was not quite 3 months old and the brewer’s friend calculator says a 1 liter starter should still be large enough.
Thanks
