The problem with tipburn is that the physiological disorder caused by low levels of calcium in the leaf tips, but this is not the result of a lack of calcium in the nutrient solution.

Increasing the calcium, if it is already present in adequate quantities in the nutrient solution will have no effect if tipburn is occurring as environmental and internal plant conditions are what causes the problem.

It is the rate of transport of calcium through the xylem tissue conductance has been found in the plants grown with the CALCLEAR units, so this is what causes the lower tipburn incidence in crops treated with the conditioner units.
