It is possible to produce fruiting buds and nodes with less than half the distance between them than what is common. This is true for many different crops.
Shoot length is determined by the amount of vegetative growth energy that is present within the plant. The node spacing is determined by the amount of reproductive growth energy, and the balance between the two forms of energy.
It is possible to produce an eighteen-inch long blueberry shoot with 24 buds along those eighteen inches. Or with only six buds on those same eighteen inches. Imagine the difference in future yield potential.
The same concept is true for most reproductive crops, tree fruit, nuts, vegetables, grains. Basically, any crop that has the capacity to produce multiple buds per node, or vary node spacing.
Learning to manage vegetative vs reproductive growth energy, and the mineral balances that determine this balance can result in some very high returns on knowledge.
