I'm using coco/perlite and I think I might want to do a flush or two.
I know it should not be done in the trays. So do you just lift them out, keep the air lines on and put in another tray and flush with water and let them sit? What about the nute feed? Turn off the rez? Or can I leave it on and the trays will not overflow?
