One of these Aztec agricultural techniques is starting seedlings in soil blocks, which does what we now call "air pruning" to avoid seedlings becoming pot-bound.
I'm wondering if jute twine could provide sufficient wicking of water in such a system of soil blocking?
Yeah has taken years for me to wrap my brain around air prunning, and a bit longer for me to test if what I thought was happening really happening.
The best thing to do is to test different wicking materials cotton will work, but it will rot out about every 3 months and has to be replaced.
I have tried soil blocking, but it takes expensive soil mix to make it work for me, this method works with my soil mix and saves me $$$.
I love experimenting....
