Sorry for the delayed posting of pics. We've been trying to help some family in Denham Springs, that got flooded out, as much as we can. We bought a pickup truck's load worth of used furniture and beds to temporarily get them started.
So, here are my pics. Please remember these are experiments to see the benefits of air pruning. I have never tried anything like these pots (or grow-bags) before. I have no results to post. All are recent re-pots and up-pots.
The first pic is of my one suggestion for using the reusable grocery bags. The ones like you could buy at Wal-Mart. But I bought mine off eBay for less than a buck a bag. There are several videos on-line for using these in gardening. For fig trees this would definitely be only for a season or two.
The rest are items that I found at .99 cent stores, dollar stores, etc (my wife loves these places). Basically anything that is the size I want. Then I line them, if the holes are large enough to need it, with landscapers fabric. Items cost from .20 cent to a buck a piece.
I also get square 5 gallon bucket from a local donut franchise for .50 each. I have several design trials of these going too, including a SWP/SIP design.
I will say that all the trees put into the bags, and then kept in a shallow water tray, have exploded in growth.
