Air circulation can be very important when growing indoors as the environment can create a warm temperature for plants. It also helps with odor control as many plants will create a strong unwanted odor. As well, CO2 is often used with indoor gardening and fans can be necissary for this process to make sure the CO2 is circulated properly. Below are several forms of common fans we suggest for your indoor garden.
Good air exchange and circulation is a vital part of controlled environment gardening. Plants increase humidity and use up available carbon dioxide rapidly. Controlling temperature, humidity, and Co2 availability can be easily achieved with a squirrel cageblower fan and a length of flexible dryer hose.
The fan is hung or mounted closer to the ceiling than the floor,forcing warm stale air out through the dryer hose. Cool Co2 rich air is drawn in through cracks or vents closer to the floor.The fan may be cycled by a timer or connected to a thermostat or environment control device.This allows the grower to give the plants an optimum aerial environment at all times. Blower fans come in a wide variety of sizes, and are rated according to the amount of air the move per minute. A 245 C.F.M. will displace 245 cubic feet of air in one minute.
The AMU squirrel cage fan will solve all of your fan needs. The series are available to handle
75-1100 CFM in a variety of sizes available.
To choose the right fan for your grow room, first determine the size and average temperature range of the area. If a cooling effect is required, which is usually the case; the fan should be large enough to change all the air in the room in about three minutes or less. A 400 C.F.M. fan should be adequate far a 1200 cubic foot area, unless the room gets unusually warm.
In an outdoor garden the CO2 level in the air is about 300 parts per million (ppm). Plants thrive when they are able to take in a higher level of CO2. Growers today monitor their greenhouse CO2 levels with special purpose control monitors, which in turn operate CO2 burners or generators to replenish CO2 consumed by the plants.
