At one point I'd like to try autopots with a living organic soil especially with the ease of watering..Now I know you fill a resevoir and the system is gravity fed..Thing is, I like to give teas once in a while..So if the resevoir is just plain water, I would hand water in the tea like I usually do no? What I mean is I wouldn't want to overwater if the medium is being controlled watering wise by a gravity fed system when I want to add a tea..So that confuses me how I would do that or maybe I'm not thinking right.
