Optic Foliar

Most plant growers know that the plant leaves are the ‘factories’ where plants produce their own food from carbon dioxide and water in the presence of sunlight or supplemental lighting and chlorophyll. It is the chlorophyll in the leaves (usually green) that absorbs light energy to produce sugars (food) for the plant and oxygen to be released into the atmosphere. The epicenter of the manufacturing facility in the plant leaf is called the palisade mesophyll layer.

The water and nutrients that plants take up from the growing media through their roots, are transported through the stem to the leaves ― to the manufacturing facility of the plant. The main objective of foliar sprays is therefore to apply water and nutrients directly to the leaves where it can be absorbed and used in the manufacturing process virtually immediately. Foliar sprays do not replace the function of the roots and stem, but it supplements this function periodically to enhance plant growth and plant health.
