The regular replacement of fresh, C02 laden air in the growing space is of huge importance, and without it one can expect low yields of low quality product. The Kiwiland Growshop gives professional advice on how to set-up an air-system that will meet your needs and you can read more about this in our tutorials section. A basic rule however is to calculate how many watts you are using, and divide this by 2 to get the approximate amount of cubic metres your exhaust fan needs to be able to pull (then add a little to make up for the carbon filter). For instance a room with 3 lamps x 600Watts is a total of 1800Watts. Divide this by 2 and you get 900. Your required exhaust fan for this room is 900m3. Round this up always to an available size which in this case it would be 1000m3.
Carbon filters are a must for complete piece of mind. Other options are available but nothing else offers the same level of smell suppression. They are big and heavy but once installed they offer a full years smell-free growing or more. Filters come in different m3 sizes just like the fans. Don't skimp and try to use a filter with less capacity than your exhaust fan.
Air circulation is just as important as air replacement and the growroom should be set-up with this in mind. The basic rule is that all the plants should be moving in a breeze every few seconds. This can be achieved with the help of large ground fans and smaller oscillating fans.
