There are two types of electron microscope, the Scanning Electron Microscope [SEM] and the Transmission Electron Microscope [TEM]. Scanning Electron Microscope shows the external and whole image of a specimen such as a dust mite, or a nit. The Transmission Electron Microscope is literally the opposite.
Combat Extremeâ¢ Southern Zone - is a 3-way mixture of turf type fescue and Hybrid Bluegrass which is heat and drought tolerant enough to be used in USDA Zones 8 - 10 (partial shade recommend for USDA Zone 9 and 10). This mixture is approximately 90% turf type fescue grass seed and 10% hybrid bluegrass seed by weight. By seed count, this makes almost a 50/50 blend of fescue and hybrid drought tolerant bluegrass.
Plant fescues when fall temperature reach about 75 F. The next best time to plant fescue seeds is when rising temperatures in spring reach 60 F. Summer isn't a good time to plant fescue lawns, because fescue grass tends to go dormant during periods of high temperature.
