or their community. Proudly representing Cannabis crops grown in Colorado by Coloradoans, their belief is that the crops they grow are a means to improve the lives of their patients. To be “Strain-wise” is to be knowledgable. It is this philosophy that provides their customers assurance that their medical Cannabis provider is a source that not only offers a consistent variety of quality product, but also a provider that cares to create a professional experience and comfortable environment for its diversified community of patients. Whether it’s through pain management, appetite stimulation, or control over anxiety and insomnia, Strainwise is a provider that can achieve their patient’s goals.


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

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 strains and number of plants per strain tested varied among the lighting tests and are summarized in Tables 1 and 2.

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 The Ryall Group chose the Lighting Science GrowAdvantage Highbay fixture 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 energy-wasteful HPS lighting to the LED solution as well as participate in the optimization of the installation for maximum benefit.

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. In the head-to-head strain comparison, all but one strain showed 100% increase in conversion efficiency (g/kWh). The increase in revenue potential with the yield increase for LED comfortably made the ROI less than four months. An additional energy savings for heat removal further adds to the overall ROI.

“We were at first skeptical about testing LED technology in our grow facility. We had little experience with it before and knew or heard about it was that it didn’t live up to the performance claims. We were impressed with the expertise Lighting Science brought to the test and the data shows tremendous results” said Rob Jany, Head of Cultivation - Genetic Resource Mgmt. at Strainwise “The projection of yield improvements and visual quality of the product is something we are very interested in for our future plans. We are pleasantly surprised by the results.”
