The Double Colander ------ is this it's use.

[oddirt]

You know throughout all of this, what came up was, what really limits a tree in a pot ?
Also the air-pot folk grow their trees in pure compost.
We also have some of the larger sized air-pots.

So I wondered if you put a tree into a colander using Bonsai type soil, and later when it had grown in,
what would happen if you then put into the air-pot ?

And so another experiment begins. The compost will drain well in an air-pot and some fertiliser will
help.
Now the tree/s to test, hmm.
Let you know in a year or two.

Hi @Anthony, being a scientist, I’m curious about the outcomes of your experiments. More empirical evidence can only improve the technical aspects of the art.

@oddirt ,

the double colander is for folk who have no ground growing space.

You can add an inorganic or organic that holds more moisture and
nutrients as you add colanders.
The J.B.pine is as conifers go a softwood. A branch extension of 3 feet / 1 m
will add on an inch / 2.5 cm to the trunk. This extension can be top
or side branches.

With our Caribbean /Honduran pine blend [ a hardwood ] those extensions
don't work. Must use open ground.

This information is really for folk who grow from seed.
Good Day
