This is the first of two videos looking at ventilation and air filtration/odour control. In this video we look at the 4 reasons for ventilation and get an idea how often you need to change the air in a grow space. Later it covers the different types of fans (axial and radial) and the strengths and weaknesses of both types.
The second video will cover air filters and the different types of activated carbon (charcoal) used in them and the difference between the types and which is most suitable for grow space odour removal. Finally you will get to see a revolutionary new ventilation system from Plant Photonics which has been designed from the ground up for tent and small cab growers.
