ALTERNATIVE HEATING SYSTEMS is pleased to introduce their latest
product for the commercial greenhouse operator, the
“Germinator”. This energy saving, heating system
promise to put your hard earned heating dollars to best use, at the “Root”
of your problem.
Most
greenhouses operate on the concept of heating the entire air mass of the
building. While this does provide optimum comfort for
employees and consumers during periods of little or no sunlight (ie.
Cloudy days or night time), it is not an efficient way to best serve the
needs of your valuable crops. AHSI has developed a
product that puts your money where it is needed most…at the root system of
your plants. 
“Root
zone” heating has been utilised for years by many growers.
AHSI takes the concept a step further by offering a system that has
significantly more flexibility than the “traditional” root zone heating
products. With the “Germinator”, the grower has the
ability to start hard to root plant stock under optimum root zone
temperature conditions, while significantly decreasing the air
temperature of the greenhouse.
Providing heat to the roots at the early stages of development can
be the difference between an average crop and an outstanding
one.
Once
established, these plants can then be taken off the heating system and
replaced with another crop that is newly potted. In
this manner, the grower can plan the most efficient use of valuable
space.
Alternatively, the grower may elect to keep the crop on the heating
system and thus reduce the duration of the cropping cycle, and
consequently the energy use of the crop in question.
The
flexible nature of this product comes in the form of its
portability. The grower can move this system to any
part of the facility that has a 120V, 15 amp circuit.
The system consists of individual heating pads measuring two feet
by four feet. The units are used with remote
temperature sensing controls. Most temperature
controller can accommodate up to eight individual heating
pads. 
To verify their claims, AHSI teamed up
with The University of Manitoba, Manitoba Hydro and a commercial
greenhouse operator. A research study conducted in the
winter of 2002 showed that it is possible to grow crops at significantly
reduced air temperatures. With the use of the heating
system, the researchers were able to show that geraniums could be grown at
an average night temperature more than Ten Degrees
Celsius cooler than the control.
This study
suggested that two new strategies are available to the
grower. First, plants grown on the heating system
under conventional air temperature can be brought to market
earlier. Second, the air temperature can be
significantly reduced without loss of marketability.
In the second scenario, the crop would be market ready in
approximately the same time as the crop grown under so-called
“traditional” temperatures. Both of these strategies
would result in energy savings to the grower.
