Please explain if both pots have drainage holes? What really are the advantages of the below ground method especially in the tropics. I understand they would be more stable but above ground pots can be staked off & trees acting as wind breakers planted around the area. This method to my mind doesn't prevent rootboundness it allows dwarfing of the tree by containerising the football as does above container planting. Again irrigation can be applied via drip irrigation similarly effectively & efficiently mulching to minimize . waterloss . Hmmm it's to me kinda overkill but maybe I am missing something.
usda zone 5b grower here. Main reason for pot in pot growing system is reducing season extremes. Most of commercially available plastic containers are black so in hot summer they might warm up to 55-60C which usually decimates roots on south facing side. In winter, it protects roots from freezing, so no overwintering structures are necessary which is quite time saving to be honest. And a nice bonus is plants staying upright and not getting blown over.
A lot of growers use a copper spray-lined pot that kills the sensitive root tips as they reach the pot, and some are switching to root bags or other air pruning pots.

Very informative. Thanks for producing this video!
Would this work small scale in a garden with a raised bed (instead of drainage underneath).

Ok thanks I've never seen this methodology before thanks for explaining
That's so much Pot that I thought this was the University of California or something!
What is in the substrate?
좋은정보 공유 감사합니다
Thanks
Do you have a source for the pots?

All the links are provided at the end of the video
ditto thanks
And since they are not letting those inner pots air prune the roots, all those "BIG" trees are permanently rootbound by the time they are sold

I have heard that if you line the production pot with landscape fabric and that will prevent the trees from becoming root bound.

That's cool thanks
I saw UK and thought UK ..... (United Kingdom :-) )
Pot-ception!
This is a very bad idea on the long term. The trees communication is totally blocked by having the trees in pots.
It isn't for long term its for sale of trees
