I've found this to be more a case of genetics...

I'm not doing a small grow... I'm doing a normal grow in small pots.

I can understand that I may not have explained this properly enough...

It is my belief that roots are merely a mechanism for the plant to uptake nutrients. Their role stops there. That's it.

If it were the case that plants emulate their root systems then my plants wouldn't look anything like they do at the moment.
