Default Understanding growth rate

I purchased the Mr. Malty calculator on my iPhone, but I'm a bit confused on what the growth rate is. All I see is a number going from 2.00 up to 6.00. What does that mean? I see where the packs and liters change, but it just doesn't make a lot of sense to me.

Thanks

That number is the amount you want to grow the initial yeast. If you set it to a growth rate of 6 the original yeast will be allowed to multiply 6 times.
. Put a ridiculously large brew in (like 20 gallons of a 1.100 wort) and move the slider and you will see the number of yeast vials change.

Ah, ok. That makes more sense now, thanks.

By the way, is there any secret to getting out the stir stick before dumping the yeast starter in the primary?

My secret is to count the cells with a microscope instead of making a starter. :-D Sorry, I don't have a trick for that. Maybe someone else has a good idea.

No worries, I'll start a new thread with that question.

Thanks for the help.

You can use a magnet on the outside of the flask to hold the stir bar. I use my spare stir bar.
