How important is air flow?
Air flow is arguably one of the most important aspects of a grow room or greenhouse. Not only does it deter mould and fungi developing, but it also provides much needed CO2 for the plants overall growth and development. A well ventilated room will yield more then a room with no ventilation. The only time this is not the case is if the room is controlled with a complete climate control system. In such a room, air-conditioners and CO2 injection system are essential. CO2 is then introduced not by airflow but through a designated injection system. It is important to note that CO2 injection works best in a completely controlled climate. To understand why ventilation is important consider the goal of setting up a greenhouse or grow room. The aim is to mimic the outside environment in a controlled and therefore higher yielding area.
