For those of you that know me, my goal with aquaponics as of right now is to learn by experience (my own personal system) in hopes that in the future, I will be able to operate a commercial farm of some kind. As I wait and learn, my mind is considering various aspects of one day owning/operating a business. One concern I thought up was the issue of neighboring commercial farms and the effect of their pesticides on my "organic" plants (whether they be certified or not). Does anybody have any thoughts on greenhouse location with surrounding commercial farms as a factor? Is it best just to avoid being by them altogether or can air filtration be an effective solution? Or is it even a concern?
Good point, it's improbable that you are going to be able to exclude every form of synthetic chemical and pesticide. It's going to come in from somewhere. I'm not really anal about the "purity" of my system as much as I would like to cut out as many harmful chemicals as is practical. Growing organic is a process/lifestyle, not a guarantee that there are no synthetic chemicals. It has to do with matching nature in the way it was designed to produce food by allowing life's processes to do their job and not messing with them in a way that would be harmful to get maximum production.
