These containers seem really interesting... Adding air to center of the root system by way of a mesh cone. I suspect they would work well to prevent overwatering but at the same time not dry as fast as root trainer pots or fabric containers. The Youtube videos comparing different designs look good for this one. Has anyone tried with figs? They are probably more designed for annuals, I can see fig roots being hard to remove but maybe it would not be so hard since you can trim them first through the underside of the cone.

Very cool design. Yesterday dave posted air pots. Now,warrior pots. Like the design. May have to one of each. Take a look at daves post about air pots

Richie I did read and comment in Dave's thread already... They have been brought up many times in the past. They never gained much in popularity, probably because of the high cost and funky appearance, they also need more water also which is tough for people in drought prone areas.

I don't really see any benefits to this pot.  There isn't going to be that much air transfer in the middle section there.  The tree is still resting on the ground, meaning that fresh air is never going to get into that section in the first place.  In other words the interior air is stagnant.  Kinda like if you wash a cup and place it face down on a flat surface it never dries. 

Not sure if roots would grow into the space in the middle or not.  They might air prune.  But if it's really humid in that interior cave section they might actually grow through it and into the ground.  Don't see how either would be helpful.  Roots would still circle around the outside edge of the pot like crazy. 

The narrow bottom might help to reduce or eliminate the perched water table phenomenon, but I don't think that is really an issue with figs.

Am I missing something?

When it gets watered that will bring in fresh air as it drains, the air will also expand during the day when it warms and then contract at night when it cools which will suck in a tiny bit. I have a hunch that is one of the reasons fig cuttings do better outside. If it was on a deck or something a small crack would probably be enough to change the air completely once a day.

That is a good point about the roots growing freely into the humid area, I didn't see the bottoms of the container in the videos I watched. It does look like the roots will circle at the bottom to me also.
