DIY Root pruning pots

[AFP]

I like the idea of air pots, and smart pots, but cant obtain them locally.
Making a root pruning pot is pretty simple, this guide shows you how to make one out of landscaping fabric, and a milk crate.

Landscaping fabric is really cheap, and is easy to work with.

Any thoughts?
