One of the most important things in a medical cannabis greenhouse or indoor farm is to keep the air constantly clean. “There are many risks associated with non-clean air in the growing room,” Joe DiDonato, managing director with Pur Distribution explains. “The most dangerous one is mold of course. We have seen many growers who had their products pulled off the shelves because of mold presence.”
Pur Distribution started its activities in the residential industry, and then decided to bring its indoor air quality solutions to the cannabis industry. “We make air purification systems for the cannabis industry, and also for the residential industry,” Joe says. “Our solutions helped remove all the chemicals and volatile organic compounds produced by construction renovation. Our system was introduced that way, and then we veered to the commercial applications.”
Removing air pollutants
With regards to the cannabis industry, Pur Distribution solutions bring many benefits, according to Joe. “Our system helps remove mold from the crops. Additionally, it helps remove air pollutants,” he points out. “Thanks to our unit’s functions, it can preserve the life expectancy of lights, as there is less build-up. They keep the room clean.” Joe takes care to remark that Pur Distribution’s solutions are suitable not only for growing rooms, but also for “the packaging room and the cutting room, where there are a lot of particles in the air. Our system helps remove them. One of the reasons for mold development is the temperature fluctuations within growing rooms. Part of the room can have mold issues when there is temperature fluctuation,” he explains. “Our system helps to fight the mold. It doesn’t help with the air circulation itself, but it helps remove the mold.”
Joe further explains that Pur Distribution’s units are equipped with a five-stage filtration. “In one unit there is a five-stage filtration concept that keeps the air clean. It has a pre-filter and a HEPA filter; it also has UVC lights – which are non ozone-producing and thus safe for the plant. Then, there is a PCO filter, and a VOC filter.
“Because the prefilter is the first filter, it gets changed periodically as it’s the one that catches the most particles,” Joe points out. “Whatever goes through gets to the HEPA filter. After this, it goes through the UVC lights and then the PCO filter, which is the photocatalytic oxidation one, and finally through the VOC filter.”
Suitable for any sealed confined space
According to Joe, the systems are suitable for both greenhouses and indoor farms. “Our systems can be deployed in any sealed confined space.” Joe further recounts the experience of a Canadian licensed producer (LP) who installed Pur Distribution’s units in their operation. “There was an LP in Canada who had mold issues. He installed 8 units in his room, which was a very large room. Within three weeks he was happy: he was fighting the mold, and he was keeping the air and the light clean.”
