Got it. Sounds like an internal fixed-minimum air gap that air prunes roots?Yes the air gap has to be enforced whereas it's impossible to violate by filling up the reservoir.
@Azimuth?
@Hashhound?
Ok.In my containers the gap or the ceiling of the reservoir where above the soil sits is hard set to 6 in.
Ok, got it!I however have a hole at the 5 inch mark where any extra water is drained away so it is impossible for my water level to rise up to where the soil is. The air gap is permanent and cannot be violated.
Your model suggests that a SIP is a self-contained unit with an internal permanent-minimum air gap that cannot be violated.
Anyone have anything against that?
