Along with large amounts of water, warmth, and light, cannabis plants require a lot of fresh air. This fact makes ventilation one of the most important parts of a grow room setup. Below, you will find a few useful tricks that will help you make your marijuana plants happier and increase your yields significantly. But first, let us figure out why the health and quality of your garden depends on the grow room ventilation.
Fresh air plays a major role in keeping your marijuana plants strong and healthy. By using the right type of an air ventilation system, you can prevent and/or solve a lot of problems, including:
You can always choose a grow tent setup with a built-in ventilation system or build an effective air exchange system by yourself. Anyway, to create the perfect environment for your cannabis garden, you will need to do two things: make the air move around your grow tent and create an effective air exhaust to vent the old air out of the growing space.
When it comes to placing the grow room fans, remember that you need the air circling both above and under the plants. Plus, you need to make sure that every corner of your grow room gets enough fresh air. It would be better to use a few small oscillating fans since they are cheap and produce a nice breeze. Plus, you will need at least one strong fan to create a working exhaust system.
Just remember never to point a strong fan directly at a plant, otherwise, the leaves and stems will get damaged. Keep an eye on your plants: if you see that the leaves near the fan started to claw, you'd better replace the tent fan.
As for the size of a fan, it totally depends on the size of your grow room or tent. There are three most popular sizes of the exhaust fans: 4″, 6″, and 8″. A 4-inch exhaust fan works perfectly for the smaller spaces like small grow tents or portable grow rooms. Just remember to always check the size of a hold because most air-cooled hoods and ducting have a 6” opening. Otherwise, you will need to buy a special converter.
