The polymer composition also includes from about 10-60% by weight of an organic drying agent such as a lower alcohol which enhances the quick drying properties thereof. The compositions may also include an amount of boron, and bimodal vinylic polymer made up of quantities of high and low molecular weight (MW) vinylic polymers such as PVA.

Method of hydroponically growing plants

A method of hydroponic growing of plants comprising hydroponically growing the plants in the presence of a controlled release hydroponic fertilizer composition. The hydroponic fertilizer composition comprises a polymerically coated controlled release fertilization nutrient formulation wherein the coated formulation has an N-P-K ratio wherein the N-K ratio is substantially balanced and further comprises micronutrients and optionally chelated iron.

Process and apparatus for coating a controlled release product in a rotating drum

The present invention is directed to a process for coating a substrate in a rotating drum, wherein a pocket is created in a substrate bed into which pocket coating materials are delivered. Also provided is a controlled release product produced according to this process, and an apparatus for carrying out the process.
