@HIAZ_urbanbudfarmer, That's right , spraying with 0.5mm misting nozzles. At pressure i am using nutrient solution is come from nozzle completely white, like gypsum in water...lots off dissolved oxygen from high pressure. Solution color come back in normal after 30-60s. For recirculation its best system, less water mean less need for water chiller to work, so everything is cheaper to run
