VANCOUVER, Dec. 1, 2016 /CNW/ - Tantalus Labs announces today that it has received the first Water License issued to a cannabis company in British Columbia. Furnished under the Water Sustainability Act (WSA), the license showcases Tantalus Labs' commitment to effective groundwater resource management and sustainably produced cannabis. Tantalus Labs utilizes specialized sungrown cultivation technology, natural odour filtration, and an innovative rainwater collection and filtration system. The team is working to establish its facility, SunLab, as an industry leader in reducing the environmental impact of cannabis production. SunLab was developed to provide plants with the purest natural inputs of water, nutrients, air, and sunlight, at the lowest environmental impact. The facility replaces traditional indoor cannabis cultivation with purpose-built greenhouses, reducing electricity needs by up to 90%. The odour filtration system utilizes a bio-active medium, allowing airflow to be naturally filtered and exhausted odour-free. Irrigation water is primarily captured from rainwater, allowing for an unprecedented level of water use efficiency. SunLab takes advantage of British Columbia's abundant precipitation. The facility's roofing doubles as a rainwater catchment surface, collecting millions of liters of water annually. The rainwater is stored and passed through three stages of filtration for irrigation use through the year. As well, irrigation runoff itself is recaptured and recycled within the facility. SunLab is located on the Agricultural Land Reserve of BC, without access to municipal water lines. As a redundancy to its innovative rainwater recapture system, SunLab maintains access to an artesian well as a possible supplement for its domestic and irrigation water.
