First off I have a 5.7v power adapter. While that spins the bar fast while alone on my stir plate, when its it my 2L flask it only makes about a 1" dimple in the water. The spin seems to be fairly balanced and isn't being thrown.
My question is do I need a big vortex to get great starters? And because I simply want one anyway, do you think its my power supply or perhaps my magnets.
I have worked with the spacing and I beleive that is about as good as it will get. Thanks in adavance
No vortex necessary, but I like one anyway. I pull a tornado-like vortex all the way down my 4L flask. You can do this with any size stir bar. But you need the bar to spin fast. So, try some higher-voltage supplies on your plate.
I agree, small vortex is all that is needed. there is a link in my sig for my build and you can see the vortex is small. I used this last week and it ran for days with no issue and produced quite the population of yeast compared to the "swirl it every time i walk by" method.
