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.
Fresh air: Put a fan in the room on low to keep the air circulating. This is surprisingly important. If the air is static the plants will not prosper. Temperature: Seeds need a warm environment to germinate. They will be comfortable with temperatures between 15-21Â°C (60-70F) during the day and will generally tolerate 10-15Â°C (50-60Â°F) overnight. Heating the soil will speed up germination, even though the surrounding air temperature may be chilly. Using seed heating pads or mats, even hot-water bottles and electric blankets under your seed trays, can make it possible to produce soil temperatures in the 80's.
