Liquid Science PLANT WAX is a water soluble emulsifiable polymer concentrate which can be sprayed on leaves to form a semi-permeable biodegradable layer. Traditionally, horticulturists trim the leaves of cuttings to reduce transpiration and hence losses from dehydration before the clone has time to generate roots and begin to absorb water. Plant Wax reduces the transpiration rate of most plants that are exposed to extreme temperatures. Plant Wax is also ideal in reducing stress throughout the transplant stage. When sprayed on the leaf surface Plant Wax slows down the transpiration rate by as much as 50%, enabling the plant to put more energy into root zone development.
