In this video post, we will look at how fabric ducting and HVAC can be used in vertical farming operations to help create the right growing conditions for the plants and crops being grown. The main HVAC system connected directly to the fabric ducting, and uses secondary fans at the beginning of each rack to supply the air into the fabric duct and over the plants.The benefit here is that one can speed control the fans and create a different air pattern independently across each bed. This allows for the possibility of growing different products at different rack levels and/or starting and harvesting products at different times in the same facility.
