As with general climate, the air distribution within a grow environment can have significant influence over the environment potential and plant growth outcomes.
Air movement is essential for multiple reasons including the venting of hot air and the introduction of cool (or cooled) air, the avoidance of ‘hot spots’, where the distribution of warm air (typically to the top of the grow environment) will lead to temperature differentials, reducing the potential for uniformity of growing conditions. Furthermore, the introduction and distribution of features such as CO2, which can become depleted if not replenished by either the introduction of fresh air, or production using apparatus such as a CO2 generators.
Generally, keeping air moving within a grow environment offers numerous benefits over static air systems. Thus, utilising adequate air handling equipment and technology is essential.
