So far the tree still looks perfectly healthy. I'm going to put a bunch more in the ground.

Basically, the technique involves germinating rootstock seeds in test tubes, then decapitating them at a couple of months of age to insert a tiny bud into a small, vertical incision into the decapitated stem. Within another couple of months, the newly budded plant will have achieved typical liner size for transplanting into the field or into a container to be grown on to acceptable size for ultimate use
"The Micro-budding process begins with rootstock, a small plant with approximately two-millimeter diameter stem germinated from a seed in a controlled environment," Skaria explained. "Buds from desirable mother trees are then hand-grafted onto the rootstock, using proprietary technologies. In less than six weeks, the buds have sprouted and are ready to be planted in the field."As far as I can tell the claim for denser plantings is simply based on the trees costing less, rather than a difference in growth.
“The whole idea is to create a system that reduces costs to a point where you can plant more trees and get higher returns, especially in the first 10 years of the grove’s life,” says Skaria. “Research has proven that if you plant more trees, you will get higher returns. Now, we have a system that makes it affordable to plant more citrus trees, resulting from drastically reduced tree and planting costs.”
Skaria refers to his program as a “bailout” for Florida citrus that is bending under the weight of greening. Micro-budding is based on a modified cleft graft. This is generally difficult to do on young tissue, but a Texas nursery has developed a system to make citrus trees on a commercial scale.more on cleft grafting: http://www.fruitmentor.com/grafting-citrus-trees-cleft-graft
