have to work as hard, and that an equilibrium between temperature
and humidity level can be more easily achieved and maintained.
This factor has been one of the primary contributors to the record
harvests being seen regularly at The Grove. Looking at how Fohse's
A3i 1500-watt fixtures compare to standard 1000-watt DE HPS
fixtures in an " apples to apples " comparison reveals just how in sync
these intelligent fixtures are with cannabis. The numbers from a
recent, late fall harvest at The Grove tell an impressive tale.
In the now-typical example above from Fall 2020, the A3i system
generated an average of 27 percent more light as compared to
the HPS fixtures. This additional light led to an increase in dry yield
harvest weights by a whopping 65 percent. All of this, while using
16 percent less energy than the HPS lighting it was compared to
and in the same physical footprint of space with the same number
of plants.
Remarkable results like those at The Grove are not a fluke or an
accident and they are not restricted to Mike Howard and his team
