Well it has some kind of valve system that only gives when needed and just uses gravity for irrigation.Depends on how the container is built. Specifically does it have a built in air gap? I think that may be the system @bobrown14 uses. He grows some monster plants and leaves the garden for extended periods so even if it's not a SIP it seems like a great setup.
I see everyone using buckets or pots so no more air pruning and anti or delayed rootbound measures? as I kinda liked that not growing in round or square plastic.
Could a system be fashioned with root pouches? as I was thinking if you fill the bottom up with perlite or hydro pebbles and then soil and place them in a base like those autopots... that could be an oxygen rich wicking area?
Although with any system I've tried so far where there is a nutrient tank or a vat below the roots, roots have always tried to invade it however they could.
