Indoor growing of cannabis plants has become popular due to the relaxation of laws governing marijuana use. Both cannabis enthusiasts and commercial growers prefer indoor growing as it gives them better control of the growing operations. Growing cannabis indoors can bring a slew of problems because of the absence of the type of ventilation available in an outdoor growing environment. To approximate outdoor growing conditions, inline booster fans must be installed in the growing area.
Indoor growing of cannabis plants
Cannabis plants growing in the wild love fresh air and a nice breeze. The growth environment is drastically changed when cannabis plants are grown indoors, where there is no natural air circulation. The use of an exhaust fan is necessary to create a perfect indoor environment for your cannabis plants that mimics the conditions in nature.
Growing cannabis indoors without any exhaust for heat can make the grow area way too humid and hot, even when the grower uses only a small grow lights. Too much heat and humidity in the grow room can lead to many issues, including root problems, heartburn, and white powdery mildew. The same conditions could also lead to spider mites, bud rot, and fungus gnats, and a slew of unpleasant guests in the grow area.
Installing an exhaust fan that will draw the air out of the growing area will lead to the cannabis plants grow faster and many random problems disappearing. Indoor cannabis growers may be unintentionally hurting their plants by missing out on a few important points about air circulation and installing inline exhaust fans to vent out the heat and humidity.
Air circulation in the grow room
The way air moves around in the grow space is an essential ingredient in creating a perfect growing environment for cannabis. Indoor growers of cannabis need to create a better-than-nature environment for their plants. The way the air moves has a big impact on how cannabis plants will grow.
When growing cannabis indoors, the plants will be in a relatively sealed environment bereft of regular access to wind, causing some problems compared to growing outdoors. Good air circulation benefits the cannabis plants in the following ways:
- Air circulation protects cannabis plants against bud rot, mold, and white powdery mildew
- Air circulation will make the cannabis plants less likely to get fungus gnats and spider mites
infestation - Air circulation strengthens the plants’ stems by allowing them to sway and bend like in
nature - Air circulation helps control heat and humidity to create a perfect growing environment
As air blows over the cannabis leaves, it carries away moisture released during transpiration, allowing the plants to drink more water and pull in more nutrients at the roots. The regular removal of moisture on the leaves lowers the chance of the plant running into a mold, while powdery mildew, or bud rot.
Temperature and Humidity Control
Good air circulation combined brought about by an exhaust system will help disperse heat and water vapor evenly throughout the growing area. Oscillating fans that blow above and below the canopy of the plant will help equalize the air, eliminating hot or humid spots.
Inline Exhaust Fan
Every indoor cannabis grower knows that getting the right equipment is a necessity but the challenge lies in the number of variations for the same equipment. Indoor growers will not question the need for an exhaust fan but choosing the right one out of the many brands and sizes will require recommendations from experts.
A good quality booster fan is the most important equipment indoor growers could buy. The inline booster fan will ensure that enough CO2 will be available for the plants. Having a carbon filter fan combo also helps in circulation, as well as improve the odor in the room. It will also ensure that the air is kept circulating and constantly replaced with fresh air frequently.
There are different sizes of inline fans. The type of fan to use depends on the grow tent as well as the number of plants. You can use 4-inch fan for smaller tents, or with only a couple of plants Larger tents require more than one 6-inch fans.
