Top quality medical
marijuana grower and
dispensary gets LED-wise
for increase yields, energy savings, and
improved quality.
Strainwise is a top-tier medical marijuana grow facility and dispensary
with 6 locations in the Denver metro area and an additional 2 in the Rocky
Mountains. They also have the distinction of being the recipient of the
very first recreational marijuana sales license in Colorado. Strainwise is
committed to consistently producing the highest quality product and strains,
and the greatest value for their patients.
CHALLENGE
For the owners of Strainwise, reducing the costs of production via energy
savings are an important part of their business model. In an increasingly
competitive MMJ market, business owners need an energy saving solution
in order to compete by lowering operational costs, increase yields, and
not affect quality of their product. There has been a significant black-eye
syndrome with regard to LED technology for grow applications. This is a
result of poorly performing fixtures, erroneous or misleading marketing
claims, and the lack of experience and knowledge from manufacturers
on what and how to measure light in the correct units for plant lighting
applications. Lighting Science has invested in providing top engineering
and photobiological expertise in the development and support of their
GrowAdvantage product line. After discussing the potential energy savings

their operation could achieve by converting
1000W HPS lamps to an LED solution,
Strainwise put the LSGC GrowAdvantage
highbay fixture to the test.
SOLUTION
Lighting Science GrowAdvantage Highbay
fixture was selected as the best solution for
the flowering room installation-for both the
highest light output and highest efficiency LED
grow fixture on the market. Additionally,
Lighting Science provided subject matter
expertise in the conversion from the energywasteful HPS lighting to the LED solution as
well as participate in the optimization of the
installation for maximum benefit.
Two tests were performed consisting of 40
strains grown under 12 1000W HPS or 23
390W Lighting Science LED fixtures during
the 60 day flowering cycle. Each lighting test
was performed on a 8’ x 24’ table. The number
of strains, and number of plants per strain
tested, varied among the lighting tests and are
summarized in Table 1.

By replacing half the fixtures in a typical Strainwise flowering room,
an average 24% increase in dry bud yield was observed while using
47% less electricity to create the light. A significant 83% increase in
efficiency was also observed (g/kWh). An additional energy savings
for heat removal further adds to the overall ROI.
