Ventilation is key

Ventilation is a key factor in the success of your grow. Ventilation keeps your temperatures down, relative humidity in check, and ample co2 in your room to keep the girls happy. Looking at the size of your room find a fan that has ample CFM to change the air in the room couple of times a minute. This is another item to consider spending a little bit more on then the cheapo fan because they tend to be pretty noisy. The bigger the better to be more efficient and their speed can always be dialed down with a speed controller. A bigger fan running at half speed is better than a little guy running full speed ahead.
When ventilating the room, make sure that you take appropriate measures to destroy any unwanted odors from giving your grow away to an unwanted audience. Carbon filters are the perfect choice for the task. They come in a range of sizes and the key to picking the right unit is its CFM rating. Make sure it is rated for at least the CFM of your fan to work appropriately.
