First time stirstarter user question

[benzy4010]

Probably to hard to tell but does this look like enough of a vortex? It's turned up about half way maybe a tad under. How long do I leave it on the plate like this? Brew day is sat

Yeah, it's stiring good enough. You don't need your yeast pulling 5 G's to make a good starter. It should be done by tomorrow, so just shut it off and let the yeast settle. If it's low floc, then throw it in the fridge. You'll know if it's done when it looks milky and smells yeasty.
