Feeder roots begin near the surface, not in the depths. The first 4 -6" of the rootzone are the most important, and what everyone calls the tap root is seeking water not O2 and nutrients.
Here's a quote from Dutch Passion's blog

Q. What is the cannabis tap root and why is it so important
- The tap root is the strong main root which emerges from a germinated cannabis seed. Experienced growers know it is important not to damage the tap root, doing so will slow down plant growth. But contrary to popular opinion the tap root is not essential to cannabis growth, plants grown from cuttings don’t have a traditional tap root yet they still produce large plants which are genetically identical to the mother plant.
My point is I don't see where the length of the tap root has any bearing on plant size. I find no science to support your conjecture. I want to see a comparative grow of seedlings allowed to stretch this much VS normally grown plants. And one of each is not a valid test.
i never made any inference to it being hard to do, i question the validity of doing so.
And a myth is is a story told to you by anyone else that has no supporting evidence. And I didn't say you started a myth, but that you may be spreading one. If we were to believe every old tale told by old time cannabis growers, we'd all be planting according to the signs of the Zodiac and pissing on our plants while chanting and dancing backwards.....
back up your words with evidence, not hostility. What I post isn't put out there to annoy you, i don't know you and have no reason to. I post replies to stimulate a discussion that may or may not bring out facts to support or deny a statement. If that offends you, it wasn't meant to. i'll not however apologize for stating an opinion, injecting factual information, or questioning anyone's assertions regarding how plants function.
