Making a starter for Brett

How slowly would Brett grow on a stir plate? Planning to do an entire beer fermented with nothing but Brett 8)

I’ve had brett starters from Orval dregs ready in 4 or 5 days without a stir plate, others took a lot longer depending on the bottling date.  If you’re using White abs or wyeast  it shouldn’t take much longer than any other yeast.

Great ;D
