I think the bacteria is small enough but the fungi spores will most likely not make it. In the book "Adding Biology" by Dr. Elaine Ingham there is a part about the use of active aerated compost teas as a foliar and it is pointed out that even pumps with the common magnetic driven propeller will damage fungi due to their longer size compared to bacteria. I always thought the purpose of an atomizer/ fogger was to create very small particles, some even use heat and pressure to do this maybe even killing the bacteria. If I were using high grade bennies which im sure you are I would do everything possible to keep them alive. Why go to an internet forrum, get something better than the top shelf at the hydro store, wait for it to arrive, then kill it. The only sure way to test a sprayer is to make a batch of bennies and put it under a microscope for a basic life count ( if youve tried this you know why I say basic count) . Then use your sprayer into a jar and put it back under the scope, in theory any less life was caused by the sprayer.
