just wondering if anyone has experienced this or has any insight. Im in the process of setting up my first HPA system and as ive seen nuts settle in the bottom of a reservoir, it seems like this could happen in the bottom of an acc. tank over time. Which depending on the position of your tank, could give a very diluted or concentrated spray to your roots! Unless the high pressure inside the tank prevents this? I know the size of the tank and flow rate of your nozzles comes into play with how often the pump kicks on and stirs things up, I have a 14g tank with 5.5L/hr nozzles x 16, 1 sec on 2 min off. experienced input would be appreciated. thanks!
