The finest re-fillable mister I've found comes on a product made by Neutrogena to treat dandruff overnight- it's their salycilic acid anti-inflammatory spray ("Neutrogena T-Gel Overnight Dandruff Treatment") and has a weird-lookin' nozzle on it that supposedly gives a VERY fine mist for a non-aerosol product. Hang on let me see if I can find a pic of the shit. There. Lots of specialty hair products come with very high-quality, low-droplet-size misters. I'm not saying they are as good as an ultrasonic mister but certainly better than a regular spray bottle for small applications.
Come to think about it i remember growing up a hair spray that came out with a pump instead of aerosol. It also had a decently fine mist.

I take it you've used this neutrogena bottle before?

I bet something like this would work equally as well since this is going to be a foliar application. I could setup a bottle with a fan/cap/hose at the top to be able to mist the plants.

Cheaper Mister

crap I don't remember if we aren't allowed to link or if that is just for seed banks and stuff. This place is a science supply store. If it's not supposed to be there I apologize and a mod can remove it.
