Im slightly confused mainly because I can find little to no info on this topic. Currently I handwater in coco and smart pots, mix up 2 gallons of room temperature well water, add nutrients, and feed. I would like to automate feeding 2-4 times a day (system is already built with drip lines and "sprinklers" (they spray a 5" circle gently) My question is if the resevoir needs to have air stones to add dissolved oxygen to the nutrient water, or is the exchange of air in water that happens when you feed plenty for the roots? My pots are also fabric pots so I feel no shortage of oxygen is in the root zone, but I distantly remember being told there are various types of 02. I understand more DO is probably a good thing, but I like simplicity and maybe my 68* degree water already has plenty of DO and is all the plants need, making it moot to add another component to the system I am using generaly hydropoincs flora series, which is not thick and does not settle (atleast in the 15 gallons I mix and use in a week) so I am not interested in adding another pump to this resevoir simply to stir the nutes, as I dont feel that necessary with this nute line. Curious for some opinions!
