So here is my bonchi-trial project
It grows lots of leaves.
The Root is not as nice as it had to survive a hard thunderstorm in july with big hail.
But I love it, it grows.
Next steps are getting the roots out of the foil and  wireing the leaves...

So, ill post some pics later this afternoon, but one of my two bonchis survived
The Chupetinha died, but the NuMex Twilight one survived, grows lots of leaves, AND it already starts to flower 
Ill post a pic, i didnt care about the roots first, so i guess what you tried to say before is you can "dig out" the roots afterwards, after the bonchi survived ?

When do you start to attach them ?
Which tools do you use to attach them together ?
Will they merge ?

Thx an BR

Thanks
One last question:
How do you get those "snaky" stems ?
Do you attach some small plants to each other while you grow them ?

Thx

"You have to prune all the small roots and leave only the big ones, there are definitely some a bit thicker ones hiding under the small roots.."
So you mean after digging out the stem after cutting it to "bonchi" size, i should remove ALL of the small roots ?

Will the remaining "few" keep it alive ?

Hi
Fascinated by your bonchis I tried to follow your instructions yesterday and cut down one chinense (chupetinha) and annuum (numex twilight).
Now the stems look promising, only the roots look very thin compared to yours.
Any hints how to thicken them ?
Any hints for next season to grow thick stems ?

I have some baccatums with nice stems, but the first branches are way to "high" so you can not cut them down for a bonchi.

Thanks for your help in advance
