Mabre Air Systems is focused on creating the optimaal environment in cannabis cultivations from the top to the bottom. “We bring simple, cost effective solutions for growers who want to be successful,” says Mike Neutel with Mabre Air Systems.
“We offer a complete line of solutions for cannabis producers including; forced air heating and cooling equipment; air distribution for commercial greenhouses, indoor, and tiered system facilities; turn-key stationary or mobile cannabis/hemp dryers; and we are the North American distributor for Cannabusters - the Odor Stopper.”
“Mabre North America is backed by Mabre Italy with 45 years of experience providing heating and drying equipment in 53 countries. Since serving the global greenhouse industry with decades of experience, time tested products and customer service; we bring that perspective and understanding to the cannabis market.”
“The Mabre team is always educating growers on the importance of air distribution.” Mike states. “if air is not moving properly within a given environment, issues can come up anytime! Air distribution is one of the most important things, but it’s often overlooked,”
He also noted, “Many things contribute to an optimum climate in a cannabis grow. Even with the best HVAC equipment in the world, if the climatized air is not delivered properly - the result will be unwanted microclimates that can cause breeding grounds for mildews, funguses and molds. Poor air distribution will inevitably compromise the success of an operation and cause substantial revenue loss.”
“We understand air movement and how plant materials react to it, we are experts in creating the best air distribution in any cannabis cultivation” Mike points out.
Looking closer at plant transpiration, here’s what happens when the lights go out for the night: cannabis/hemp plants dump a lot of moisture under the leaf. “How much moisture is transpired depends on the plant variety, spacing and age of the crop,” Mike further explains. “But some calculations show that 3 sqare feet of cannabis can transpire as much as 3 lbs of water! That’s a lot of moisture on the leaf surface. The longer the moisture remains on the leaf surface without adequate climatized airflow, the better the chance for mildew issues.”
Moving Air- The Proper Way
According to Mike, to achieve optimum growing conditions, climatized air temp and humidity must be delivered through your plant canopy with air. “This air movement through your canopy is the “absorption pad and delivery system” that sucks up transpirational moisture from the leaf surface and returns it to your HVAC or ventilation equipment. Traditionally, HAF fans are used to move air in a grow facility, but they only affect air movement in the upper section of the canopy. It is in the lower parts of your plant canopy where dead spots and microclimates develop and problems grow. HAF fans are also not effective in removing transpirational moisture from the lower canopy leaf surface.”
“Mabre moves air evenly by spraying climatized air from the bottom to the top, throughout the canopy. Employing fabric or poly duct tubes with precise hole patterns, engineered blowers and pressure/flow adjustments, the climatized air is distributed evenly throughout the plant canopy and microclimates are eliminated. “our systems are an excellent way to deliver CO2 to your canopy as well.” noted Mike.
“Mabre blowers are VFD driven with advanced european technology. They move high volumes of air with low power consumption, reducing HVAC equipment and labour costs during construction and during operations. Mabre’s blowers also allow HVAC equipment to be kept in one location. Fewer, larger HVAC units save money because Mabre Blowers are far more cost effective as compared to more HVAC equipment.”
Mabre Humidity Control in a cannabis greenhouse
Humidity is a huge issue issue in cannabis, here is how Mabre approaches humidity correction.
“The Mabre unit creates a little heat (through indirect combustion) and moves that super dry, high flow air through the greenhouse with our duct socks,” Mike explains. “We create evaporation by chugging the super dry air and plant moisture is evaporated. Next, a slight temperature rise in the greenhouse occurs from the heat in the humidity correction cycle. The temperature increase then triggers exhaust fans or roof vents to exhaust this warmer, moister air. Humidity now drops amazingly fast as climatized, fresh and dry air takes its place through our duct sock distribution system. This process keeps the humidity at target levels, very quickly and economically.”
“It works like a hand dryer,” he points out. “If it’s blowing cold air, you will wait for your hands to dry. But, if it’s blowing warm air, your hands are dry in 10 seconds. Warm air holds a lot more moisture than cool air, and dries much faster”
