If I see small roots coming up

A customer has a question and I hope we can get some opinions on it, thanks

if I see small roots coming up
Through dirt at base of plant should I add more dirt to bucket?

Yes, roots should not be exposed to light. They like it dark. Hope that helps!

Yes but need pick you could be out growing container

with a large lack of information: hard to give informed answer.
however, adding media to main stem will encourage new root growth there.
