They blow instead of suck! Seriously, White uses a low volume of positive air pressure (2-3 oz) to push the seed into a pocket in the disc, whereas the vacs suck the seed to the disc. White meters are very accurate when the correct seed size is available. The reason I didn’t like the one I had is I rarely got the seed size I ordered and it was a pia. Vacs are much more forgiving in that respect.
