Simply put, the more precisely the greenhouse can
offer ideal growing conditions, the more robust the crop.
Heating and cooling are the basest levels of greenhouse
automation. The set points offer bandwidths for the
best growing environment. Too much water will be
highly detrimental.
" The equipment becomes like an orchestra where
certain pieces are responding, and in a very specific
order, " said Julie Dean, vice president, Wadsworth Control
Systems. " It's all about the sensors. They can determine
when to open a roof vent to dehumidify or when to close
a curtain due to an exterior light level that is too low for
the heat it's taking to keep the greenhouse within the set
point range. "
" In low-light conditions, our systems gradually engage
dimmable LED grow lights to achieve the required light
levels. This dynamic adjustment promotes consistent
growth, reduces crop stress and prevents losses, all
while optimizing energy use, " said Nick Earls, sales
representative at Wadsworth Control Systems.
PRECISION LIGHTING
One of the main challenges with greenhouse lighting
is the tendency for growers to rely on static timers
or manual switches. This often results in overuse or
underuse of lighting, which can negatively affect crop
yields and increase energy costs.
Wadsworth's controls address this by providing lightbased
automation. " Our systems integrate PAR sensors
and dimmable lighting technology, enabling precise light
management. During cloudy days, the system increases
supplemental light levels, while on sunny days, it reduces
artificial lighting to conserve energy. This improves plant
health by delivering consistent light levels tailored to
crop needs and reduces energy consumption, " added
Brent DeArmond, sales representative for Wadsworth
Control Systems.
Finally, TITAN Atom by Argus is a Canadian-based
control system that precisely commands temperature,
humidity, CO2 levels and light to mimic the exact natural
conditions plants need to thrive. Designed to scale as
needed alongside existing operations, its modular nature
enables easy expansion, accommodating increases in
scale or modifications in farming practices without the
need for extensive system overhauls.
The modular setup of the TITAN Atom control system
by Argus allows for easy expansion as it is designed to
scale alongside existing operations.
