The evidence suggests that the CALCLEAR units act to enhance xylem conductance, thus allowing the plants to transpire more effectively and therefore moving more Calcium into the leaf tips.

There is also some evidence to suggest that the units can positively influence plant metabolism and they have been shown to reduce the bitter flavour component of lettuce leaves.

The CALCLEAR conditioner treated solution may work to some extent to reduce the polymerisation of glucose molecules into starch crystals, allowing a higher concentration of free sugars within the plant cells, therefore giving a better taste.

Trials are currently underway to test this effect on tomato fruit with both compositional and sensory evaluation.
