Environment & Lights

Cultivar Farms uses a variety of lighting technologies well-suited for indoor cultivation. Our vegetative rooms utilize a combination of multi-spectrum Ceramic Metal Halide (“CMH”) and Light Emitting Diodes (“LED”) fixtures. Both of these technologies provide our plants with ideal Photosynthetically Active Radiation (PAR) for enhanced growth, along with offering the latest in grow light energy efficiencies. High-Pressure Sodium (“HPS”) lamps have been the standard in the flowering stage of cannabis for nearly 50 years. With the introduction of the double ended HPS lamp in 2010, this technology made a significant advancement in energy efficiency and overall performance. Over the last decade the industry has continued to see the introduction of other lighting technologies, “LED”, “CMH”, Plasma and Induction, that all seek to dethrone the “HPS” lamp as the king. Over the last decade we have continually devoted time and energy towards performing R&D with all have these newer technologies, individually as well as integrated together in various combinations. As of 2017, our research concluded that based on performance, affordability and energy efficiencies, (17% reduction of wattage per square foot of canopy), achieving a comprehensive mixed spectrum of reds, greens and blues was best archived through the combination of 1000-watt HPS lamps and 630-watt CMH fixture. HPS lamps provide an unmatched intensity of reds and greens that ensure beautifully dense flowers with pronounced calyxs, low leaf ratios, and high cannabinoid percentages. CMH lamps round out the light spectrum by providing the blues (UVB) which have proven to enhance production of essential oils and terpenes.

As of 2018, we are utilizing some of the newer LED designs for cannabis flowering rooms as well, and are excited about their potential for use in regards to vertical multi-level flower room gardening.
