Sure.
Some points....
* Seedlings which have there radicle (tap root) removed never (or very rarely) develop another one and subsequent growth of roots is mainly lateral
* Cutting grown plants have only lateral growth in their roots so there's no problem with them.
* It is vital for the main roots (future surface roots) to leave the trunk at a 45 degree angle. This way, as they grow, the nebari will expand with them and develop good taper.
* Placing a young plant on a tile with it's roots horizontally, they will grow closer to 90 degrees and this results in the nebari NOT expanding and the surface roots growing in an unnatural manner. Also it may develop useless roots which must be removed.
* Placing advanced material on tiles in probably of no consequence as the main roots are already set into position.
* Ground grown plants - depending on species - need to be dug and strongly root pruned every 2 years or so. During this time it is very easy to select the good roots growing at the correct angle and to remove the rest.
* When root pruning, we also remove most if not all roots growing downwards directly beneath the trunk.
* For good quality control, young material should be pot grown for the first 3 years. During this time, you can do root pruning and selection every year, (pines every 2 years) after which putting them in the ground to add wood is easy to manage and there will be no surprises.
* I have been ground growing for more than 25 years and have not seen any advantage to placing trees on tiles. In fact I consider it unnecessarily boring and time consuming.
