switch to other crops much easier. "
The same flexibility and ability to make
changes that are considered when selecting a
growing structure should apply to choosing an
environmental control system.
If a grower is building a high-tech greenhouse,

high-tech and more capable control systems.
" These environmental control systems are
designed in such a way that they are plug-andplay
types of systems. These are monitoring
control systems so as a grower keeps adding
more zones to the greenhouse the control
system can be expanded with more controllers,
input/output modules, relays and actuators as
needed. Considering expansion, growers should
look at a control system that is adjustable,
expandable and scalable in a cost effective
fashion. "
facilities to achieve the production quantity,
quality and resource savings they're expecting. "
Knowing the capabilities of the greenhouse
structure and environmental control system
could also influence future facility expansion.
" When designing and selecting the control
system and the greenhouse structure,
considering expansion would be advantageous
in terms of minimizing initial and future
costs that can be expected, " Kacira says.
" The expansion could be several times more
expensive if it is not considered when the
original facility is constructed. A high-tech
greenhouse system, in many cases, is going to
be a structure that is taller with a higher volume
and more integrated systems. There is more
capacity, more buffer for flexible environmental
controls and to be able to remove or integrate
