Ryan, that sounds basically like a hydroponic setup. We do the same thing only our pots are full of soil that goes with the tree like a root ball. Difference between that and the typical burlap root ball is that since our trees are grown from a small root ball into a bigger one and never leave the pot til you plant them there is never any cut roots to stunt the tree. What we do is popular in Australia where they grow trees up to 6 inch caliper in giant 200 gallon pots. Harder to move than a bare root tree but much better survival I imagine.
