ABS is sampling from address frames that are usually based, in part, on the USPS files. Although approaches for selecting samples of addresses for mail or in-person surveys have existed for decades, the surveyâs success depends heavily on the availability of a suitable address frame.
Water and water uptake are major factors in keeping cut flowers fresh. A process called hardening ensures maximum water uptake. It simply means placing the freshly cut stem in 110Â° F (43.5Â° C) water (plus preservative). Place in a cool location for an hour or two.
It's quite another to maintain flowers and plants at this temperature. Even if a cooler operates at the right temperature, crops themselves may rest at a different temperature. Thus, proper storage temperatures and effective heat exchange are required. The cooler temperature should be within plus or minus one to two degrees of the ideal flower/plant storage temperature. Check the average cooler temperature by measuring the water temperature in a five gallon bucket held in the cooler. All coolers should have at least two thermometers to obtain temperature ranges within the cooler. Use one thermometer as a control for the other.
