A DUCT RUN, “ THE THE LONGER MORE RESISTANCE. This resistance reduces the fan’s power and ability to move air.” Ducting Length Another important consideration when setting up a heat recycling ventilation system is the overall length of the exhaust ducting. The longer a duct run, the more resistance. This resistance reduces the fan’s power and ability to move air. Because of this, the most efficient and effective way to recycle heat from one grow space to another is to have the two grow spaces adjacent or very close to each other. If a longer duct run is required, it may be necessary to increase the fan size so it has enough power to adequately move the heated air. Assuming the grower has or can build two adjacent flowering rooms, an additional fan, ducting, and a relay or flip light controller are the only pieces of equipment needed to create a heat recycling system. NEW! CO2 SOLUTIONS FOR GROWERS “Our partnerships with key agriculture industry leaders allowed us to understand their true needs in a safety monitor. This led us to create the CM-7000 with up to 12 remote CO2 sensors all reporting back to a fully customizable touchscreen display.” —Travis Lenander, CEO • Optimize CO2 enrichment, which can boost yield by 30+%! • Accurate & precise CO2 monitoring, 0-10,000pppm • Splash-resistant design Meet the NEW GrowFlux CO2 Sensor. This new device is wireless & connected to the cloud, giving you the ability to monitor your cultivation environment from anywhere!

The ballast connected to a flip-box light controller operates continuously. A 12-hour cycle timer triggers the relay within the flip-box and the ballast’s output power is routed from one lamp to the other. Put another way, every 12 hours, the flip-box lighting controller’s relay switch engages and the light cycles of the two blooming rooms alternate. In addition to the benefit of recycling heat from one growroom to another, flip-box light controllers allow an indoor horticulturist to operate two flowering rooms on half as many ballasts. Essentially, these devices allow two light bulbs, on opposite 12-hour light cycles, to be operated by one ballast. For example, a grower with a 20-light flip-box light controller could operate a maximum of 40 lamps from 20 ballasts. Just about all flip-box light controllers are integrated with, or directly connected to, a timer which ensures the two flowering rooms’ photoperiods will never overlap and remain on perfect 12-hour lights on and 12-hour lights off cycles. Back-Up Cooling Device In the rare instance too much heat is exhausted into the lights off garden space and the temperature exceeds the desired range, another cooling device, such as an air conditioner or an additional exhaust fan, can be used as a fail-safe. A small exhaust fan equipped with a cooling thermostat is all most indoor gardens will need as a backup cooling device. • 9” LCD touchscreen for complete system control • User-configurable control settings for entire system • Field upgrade for number of sensors & gas types 42 Relay or Flip-Box Recycling heat within a dual flowering room setup is one of the best ways an indoor horticulturist, who lives in a cooler climate, can improve his or her garden’s overall efficiency. Instead of redirecting the excess heat outside, a grower can take a few steps to implement a heat recycling system. Sometimes small growroom changes can compound to big savings. When applicable, heat recycling is one of those small changes that can result in immediate benefits. Specialised equipment, such as a flip-box lighting controller, further increases the efficiency of heat recycling dual flowering room setups. Indoor growers are always looking for methods to increase their return on investment through heightened efficiency. For many growers, a dual flowering room, complete with heat recycling and a flip- box lighting controller, is the most effective and efficient method for indoor cultivation during the winter months.
