The price of the device has been steadily increasedâby 32 percent in the past year aloneâbut not because the cost of the raw materials was increasing (a typical dose of epinephrine still costs about a dollar). The profit margin of the EpiPen was 9 percent in 2008. Today itâs 55 percent.
Frost is a form of ice and can only survive at temperatures of 32 degrees Fahrenheit and below. But that doesnât mean the measured air temperature must be 32 or below for frost to form on a surface.
The location of your garden can play a big factor in whether your plants are damaged by a frost or not. Generally, air temperature lowers from 3-5 degrees Fahrenheit with each thousand-foot increase in altitude. Therefore, the higher the elevation of your garden, the more likely your plants will be hit by a frost or freeze. On the other hand, cold air is heavier than warm air and can sink to lower areas, causing frost damage.
