Yes, you can. But why!? If I were to use a host plant, I would use Premier Tech's method of mycorrhizal propogation, which someone mentioned above.
With what you mentioned, disturbance of the rootball could slow dwn the life proceses of the plant. Remember, in a natural engironment(which you are trying to create in an organic setup), roots would not jormally be majorly disturbed. Furthermore, you're essentially butchering the mycorrhizal hyphal nework you are tring to maintain.
So why mess with nature?
Well.. growing myco colonies in coffee cans isn't exactly all natural.
Hahaha
don't let me get yeh, I'm just jokin' around.
Mostly because I was too lazy to research Humus..
How much does it usually cost and where would have it?
Also because working with plants is easier/my thing.
Growing fungus in a sterile room isn't quite. Until I start growing Baby Port's.
I was thinking either Basil, Carrots, or Mint.
Since those are easily abundant for me to conduct science experiments on.
Picture an intense growing system of Basil & Mint clones, maybe carrots too.
Which would essentially be a perpetual.
Grow them until rootbound & innoculated,
then take a root ball & cut it in maybe 3-5 portions,
and use those for your transplants/clones.
The network WOULD be pissed, but who knows.
All it needs to do is resume normal growth and it will recover.
