The document discusses using the Ecke Poinsettia Bract Meter tool to help greenhouse growers efficiently manage their poinsettia crops. The Bract Meter allows growers to set greenhouse temperatures based on their desired shipping dates to reduce energy costs while ensuring plants are ready on time. It also describes monitoring plant height and bract development to fine tune temperatures and meet market demands. Using the Bract Meter and On Target tracking tool together helps growers avoid last minute stress and confidently finish their crops at the peak time.

62 F /17 C 41 36 32 27 22 17 13 8 3
starting with 49 days to market, you can
settle on an average daily temperature of 64 F /18 C 35 31 27 23 19 15 11 7 3

4. Saving energy with cold grow poinsettias
Get optimum results with
Eckes exclusive
Poinsettia Bract Meter
Technical recommendations backed by years of experience and research are an Ecke
tradition. We always provide the science behind our recommendations and the Ecke cold
grow program is no different.
Our research into effective cold grow techniques has led to the development of a new
production tool that can help any grower 鍖nd success when they turn their greenhouse
thermostats down and select Eckes energy-ef鍖cient varieties. With the Ecke Poinsettia
Bract Meter , you can eliminate guesswork and take control of pro鍖tability!
SAVE 20 PERCENT OR MORE ON ENERGY COSTS
To evaluate potential energy savings at cooler temperatures, Ecke enlisted help from commercial growers
around North America. The support of these growers has helped us demonstrate the risks and bene鍖ts of
using lower temperatures for production while quantifying the energy savings that are possible.
On average, select Ecke varieties grown colder than traditional programs achieved a savings of 21 percent ADVENTTM RED
(PER2804) PPAF
in an energy-ef鍖cient greenhouse. This number can be double that in a less ef鍖cient greenhouse.
Testing conducted in Europe helped further validate the energy savings potential
by comparing poinsettias from all major breeding companies. These tests
measured the litres of oil per square meter required at different
production regimes.
The results speak for themselves! Freedom Early Red required 23
percent less energy than its nearest competitor. Compared to
more traditional temperatures, cold-growing Freedom
Early Red is nearly 35 percent more fuel-ef鍖cient.
