Air Movement

Air movement within the grow room. A simple guide

     I have been asked to write a blog on my experiences within the ‘indoor gardening’ world. For the purpose of these blogs my name is Star Dawg. I hope these blogs will offer help and advice to beginners and or experienced growers

    A common misconception is that plants need to be moved via air movement. People argue that when the plant moves from side to side it is made stronger. This isn’t the case every time a plant moves, it has to readjust to the new environment using up energy that it should be using to grow.

   The use of wall mounted fans is to move the hot air between the lamp and the top of the plant. The fan should be raised as the plant grows and should never be blowing directly onto the plant. 

Using an Air Dump System:

   The best way to combat air stratification is with a system called an ‘air dump system’. For an air dump system you will need 1 x 100mm RVK fan and 5m of combi ducting to suit. At the half way point of the room, screw the fan to the wall 1m above the floor, cut a piece of duct, long enough to reach the floor and allow 1m to lay on the floor surface. Install the rest of the duct to the other end of the fan and fix it onto the wall and ceiling and let it hang down in the middle of 2 lights, 500mm from the ceiling. The idea is to suck the cooler Co2 enriched air from low down and let it drop onto the plant canopy causing a continuous movement of air and also giving the plants access to cooler air and Co2. Co2 being denser than oxygen will fall to the floor with the inclusion of an air dump system the Co2 is being continuously recirculated and allowed to fall over the top of the plants. This system works really well in closed systems such as Opticlimate and also works with in and out systems.
